Clay is a finely-grained natural rock or soil material that combines one or more clay minerals with possible traces of quartz (SiO2), metal oxides (Al2O3 , MgO etc.) and organic matter. Geologic clay deposits are mostly composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure. Clays are plastic due to particle size and geometry as well as water content, and become hard, brittle and non–plastic upon drying or firing. Depending on the soil's content in which it is found, clay can appear in various colours from white to dull grey or brown to deep orange-red.
Although many naturally occurring deposits include both silts and clay, clays are distinguished from other fine-grained soils by differences in size and mineralogy. Silts, which are fine-grained soils that do not include clay minerals, tend to have larger particle sizes than clays. There is, however, some overlap in particle size and other physical properties. The distinction between silt and clay varies by discipline. Geologists and soil scientists usually consider the separation to occur at a particle size of 2 µm (clays being finer than silts), sedimentologists often use 4–5 μm, and colloid chemists use 1 μm. Geotechnical engineers distinguish between silts and clays based on the plasticity properties of the soil, as measured by the soils' Atterberg limits. ISO 14688 grades clay particles as being smaller than 2 μm and silt particles as being larger.
Clay minerals typically form over long periods of time as a result of the gradual chemical weathering of rocks, usually silicate-bearing, by low concentrations of carbonic acid and other diluted solvents. These solvents, usually acidic, migrate through the weathering rock after leaching through upper weathered layers. In addition to the weathering process, some clay minerals are formed through hydrothermal activity. There are two types of clay deposits: primary and secondary. Primary clays form as residual deposits in soil and remain at the site of formation. Secondary clays are clays that have been transported from their original location by water erosion and deposited in a new sedimentary deposit. Clay deposits are typically associated with very low energy depositional environments such as large lakes and marine basins.
Depending on the academic source, there are three or four main groups of clays: kaolinite, montmorillonite-smectite, illite, and chlorite. Chlorites are not always considered to be a clay, sometimes being classified as a separate group within the phyllosilicates. There are approximately 30 different types of "pure" clays in these categories, but most "natural" clay deposits are mixtures of these different types, along with other weathered minerals.
Varve (or varved clay) is clay with visible annual layers, which are formed by seasonal deposition of those layers and are marked by differences in erosion and organic content. This type of deposit is common in former glacial lakes. When fine sediments are delivered into the calm waters of these glacial lake basins away from the shoreline, they settle to the lake bed. The resulting seasonal layering is preserved in an even distribution of clay sediment banding.
Quick clay is a unique type of marine clay indigenous to the glaciated terrains of Norway, Canada, Northern Ireland, and Sweden. It is a highly sensitive clay, prone to liquefaction, which has been involved in several deadly landslides.
Powder X-ray diffraction can be used to identify clays.
Clays exhibit plasticity when mixed with water in certain proportions. However, when dry, clay becomes firm and when fired in a kiln, permanent physical and chemical changes occur. These changes convert the clay into a ceramic material. Because of these properties, clay is used for making pottery, both utilitarian and decorative, and construction products, such as bricks, wall and floor tiles. Different types of clay, when used with different minerals and firing conditions, are used to produce earthenware, stoneware, and porcelain. Prehistoric humans discovered the useful properties of clay. Some of the earliest pottery shards recovered are from central Honshu, Japan. They are associated with the Jōmon culture and deposits they were recovered from have been dated to around 14,000 BC.
Clay tablets were the first known writing medium. Scribes wrote by inscribing them with cuneiform script using a blunt reed called a stylus. Purpose-made clay balls were also used as sling ammunition.
Clays sintered in fire were the first form of ceramic. Bricks, cooking pots, art objects, dishware, smoking pipes, and even musical instruments such as the ocarina can all be shaped from clay before being fired. Clay is also used in many industrial processes, such as paper making, cement production, and chemical filtering. Until the late 20th century, bentonite clay was widely used as a mold binder in the manufacture of sand castings.
Clay, being relatively impermeable to water, is also used where natural seals are needed, such as in the cores of dams, or as a barrier in landfills against toxic seepage (lining the landfill, preferably in combination with geotextiles). (See puddling.)
Traditional uses of clay as medicine goes back to prehistoric times. An example is Armenian bole, which is used to soothe an upset stomach. Some animals such as parrots and pigs ingest clay for similar reasons. Kaolin clay and attapulgite have been used as anti-diarrheal medicines.
Clay as the defining ingredient of loam is one of the oldest building materials on Earth, among other ancient, naturally-occurring geologic materials such as stone and organic materials like wood. Between one-half and two-thirds of the world's population, in both traditional societies as well as developed countries, still live or work in buildings made with clay, often baked into brick, as an essential part of its load-bearing structure. Also a primary ingredient in many natural building techniques, clay is used to create adobe, cob, cordwood, and rammed earth structures and building elements such as wattle and daub, clay plaster, clay render case, clay floors and clay paints and ceramic building material. Clay was used as a mortar in brick chimneys and stone walls where protected from water.
13 Reasons Why (stylized onscreen as TH1RTEEN R3ASONS WHY) is an American teen drama web television series developed for Netflix by Brian Yorkey, based on the 2007 novel Thirteen Reasons Why by Jay Asher. The series revolves around seventeen-year-old high school student, Clay Jensen, and his deceased friend Hannah Baker, who has killed herself after having to face a culture of gossip and sexual assault at her high school and a lack of support from her friends and her school. A box of cassette tapes recorded by Hannah in the lead up to her suicide detail thirteen reasons why she ended her life. The series is produced by July Moon Productions, Kicked to the Curb Productions, Anonymous Content and Paramount Television, with Yorkey and Diana Son serving as showrunners.
Dylan Minnette stars as Clay, while Katherine Langford plays Hannah. Christian Navarro, Alisha Boe, Brandon Flynn, Justin Prentice, Miles Heizer, Ross Butler, Devin Druid, Amy Hargreaves, Derek Luke, Kate Walsh, and Brian d'Arcy James also star. A film from Universal Pictures based on Thirteen Reasons Why began development in February 2011, with Selena Gomez set to star as Hannah, before being shelved in favor of a television series and Netflix ordering it straight to series in October 2015, with Gomez instead serving as an executive producer.
The first season was released on Netflix on March 31, 2017. It received positive reviews from critics and audiences, who praised its subject matter and acting, particularly the performances of Minnette and Langford. For her performance, Langford received a Golden Globe Award nomination for Best Actress in a Drama Series. However, its graphic depiction of issues such as suicide and rape, along with other mature content prompted concerns from mental health professionals. In response, Netflix added a warning card and from March 2018, a video that plays at the start of each season warning viewers about its themes.In May 2017, Netflix renewed 13 Reasons Why for a second season; filming began the next month and concluded that December. The second season was released on May 18, 2018, and received negative reviews from critics and mixed reviews from audiences. A third season was ordered in June 2018 and is set to be released in 2019. Critical and audience reaction to the series has been divided, with the program generating controversy between audiences and industry reviewers.2019 ATP Tour
The 2019 ATP Tour is the global elite men's professional tennis circuit organised by the Association of Tennis Professionals (ATP) for the 2019 tennis season. The 2019 ATP Tour calendar comprises the Grand Slam tournaments (supervised by the International Tennis Federation (ITF)), the ATP World Tour Masters 1000, the ATP World Tour 500 series, the ATP World Tour 250 series, the Davis Cup (organised by the ITF), and the ATP Finals. Also included in the 2019 calendar are the Hopman Cup and the Next Gen ATP Finals which do not distribute ranking points.Andrew Dice Clay
Andrew Dice Clay (born Andrew Clay Silverstein; September 29, 1957) is an American stand-up comedian, actor, musician, and producer. He rose to prominence in the late 1980s with a brash, macho, offensive persona known as "The Diceman". In 1990, he became the first stand-up comedian to sell out Madison Square Garden for two consecutive nights. That same year, he played the lead role in the comedy-mystery film The Adventures of Ford Fairlane.
Clay has appeared in several films and television shows and released a number of stand-up comedy albums. He continues to focus on acting while still touring and performing stand-up. He launched his new podcast, I'm Ova Hea' Now, in September 2018.Bentonite
Bentonite (/ˈbɛntənʌɪt/) is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite. It was named by Wilbur C. Knight in 1898 after the Cretaceous Benton Shale near Rock River, Wyoming.The different types of bentonite are each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al). Experts debate a number of nomenclatorial problems with the classification of bentonite clays. Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, has been used to describe clay beds of uncertain origin. For industrial purposes, two main classes of bentonite exist: sodium and calcium bentonite. In stratigraphy and tephrochronology, completely devitrified (weathered volcanic glass) ash-fall beds are commonly referred to as K-bentonites when the dominant clay species is illite. In addition to montmorillonite and illite another common clay species that is sometimes dominant is kaolinite. Kaolinite-dominated clays are commonly referred to as tonsteins and are typically associated with coal.Building material
Building material is any material which is used for construction purposes. Many naturally occurring substances, such as clay, rocks, sand, and wood, even twigs and leaves, have been used to construct buildings. Apart from naturally occurring materials, many man-made products are in use, some more and some less synthetic. The manufacturing of building materials is an established industry in many countries and the use of these materials is typically segmented into specific specialty trades, such as carpentry, insulation, plumbing, and roofing work. They provide the make-up of habitats and structures including homes.Clay Aiken
Clayton Holmes "Clay" Aiken (born Clayton Holmes Grissom; November 30, 1978) is an American singer, television personality, actor, politician, and activist. He first gained fame when he came in second place on the second season of the reality singing competition American Idol in 2003. His debut album, Measure of a Man, released in October 2003, went multi-platinum. He released four more albums on the RCA label: Merry Christmas with Love (2004), A Thousand Different Ways (2006), the Christmas EP All is Well (2006), and On My Way Here (2008). Since then he has released two more albums, both with Decca Records: Tried and True (2010) and Steadfast (2012). Aiken has also had eleven tours in support of his albums. In all, he has sold over 5 million albums, and is the fourth-highest-selling American Idol alumnus.Aiken co-wrote a bestselling memoir in 2004, Learning to Sing. In 2004 he also had a televised Christmas special, A Clay Aiken Christmas. During much of 2008 he appeared on Broadway in the musical comedy Spamalot, in the role of Sir Robin. In 2010 he hosted the PBS special Tried & True Live!. He has also had numerous cameo and guest appearances on TV shows. In 2012 he competed in the fifth season of The Celebrity Apprentice, coming in second to Arsenio Hall.
With Diane Bubel, Aiken created the Bubel/Aiken Foundation in 2003, which was later renamed the National Inclusion Project. In 2004 he became a UNICEF ambassador, a position he held until 2013 when he gave it up in order to run for Congress. He traveled extensively in this role. In 2006, he was appointed for a two-year term to the Presidential Committee for People with Intellectual Disabilities.In 2014, Aiken ran for Congress in North Carolina's 2nd congressional district. He won the Democratic primary, but lost to Republican incumbent Renee Ellmers in the general election.Clay court
A clay court is one of many different types of tennis court. Clay courts are made of crushed shale, stone, brick, or other unbound mineral aggregates. The French Open uses clay courts, making it unique among the Grand Slam tournaments. Clay courts are more common in Continental Europe and Latin America than in North America, Asia or Britain. Two main types exist: red clay, the more common variety, and green clay, also known as "rubico", which is a harder surface. Although less expensive to construct than other types of tennis courts, the maintenance costs of clay are high as the surface must be rolled to preserve flatness.Democratic-Republican Party
The Democratic-Republican Party (formally the Republican Party) was an American political party formed by Thomas Jefferson and James Madison around 1792 to oppose the centralizing policies of the new Federalist Party run by Alexander Hamilton, who was Secretary of the Treasury and chief architect of George Washington's administration. From 1801 to 1825, the new party controlled the presidency and Congress as well as most states during the First Party System. It began in 1791 as one faction in Congress and included many politicians who had been opposed to the new constitution. They called themselves Republicans after their ideology, republicanism. They distrusted the Federalist tendency to centralize and loosely interpret the Constitution, believing these policies were signs of monarchism and anti-republican values. The party splintered in 1824, with the faction loyal to Andrew Jackson coalescing into the Jacksonian movement (which would soon acquire the name Democratic Party), the faction led by John Quincy Adams and Henry Clay forming the National Republican Party and some other groups going on to form the Anti-Masonic Party. The National Republicans, Anti-Masons, and other opponents of Andrew Jackson later formed themselves into the Whig Party.During the time that this party existed, it was usually referred to as the Republican Party. To distinguish it from the modern Republican Party (founded in 1854), historians, political scientists and pundits often refer to this party as the Democratic-Republican Party or the Jeffersonian Republican Party. The modern Republican Party founded in 1854 deliberately chose to name itself after the Jeffersonians. Modern Democratic politicians claim Jefferson as their founder.The party arose from the Anti-Administration faction which met secretly in the national capital (Philadelphia) to oppose Alexander Hamilton's financial programs (see the American School and the Hamiltonian economic program). Jefferson denounced the programs as leading to monarchy and subversive of republicanism. Jefferson needed to have a nationwide party to challenge the Federalists, which Hamilton was building up with allies in major cities. Foreign affairs took a leading role in 1794–1795 as the Republicans vigorously opposed the Jay Treaty with the United Kingdom, which was then at war with France. Republicans saw France as more democratic after its Revolution while the United Kingdom represented the hated monarchy. The party denounced many of Hamilton's measures as unconstitutional, especially the national bank.
The party was strongest in the South and weakest in the Northeast. It demanded states' rights as expressed by the "Principles of 1798" articulated in the Kentucky and Virginia Resolutions that would allow states to nullify a federal law. Above all, the party stood for the primacy of the yeoman farmers. Republicans were deeply committed to the principles of republicanism, which they feared were threatened by the supposed monarchical tendencies of the Hamiltonian Federalists. The party came to power in 1801 with the election of Jefferson in the 1800 presidential election. The Federalists—too elitist to appeal to most people—faded away and totally collapsed after 1815. Despite internal divisions, the Republicans dominated the First Party System until partisanship itself withered away during the Era of Good Feelings after 1816.
The party selected its presidential candidates in a caucus of members of Congress. They included Thomas Jefferson (nominated 1796; elected 1800–1801, 1804), James Madison (1808, 1812) and James Monroe (1816, 1820). By 1824, the caucus system had practically collapsed. After 1800, the party dominated Congress and most state governments outside New England. By 1824, the party was also split four ways and lacked a center as the First Party System collapsed. The emergence of the Second Party System in the 1820s and 30s realigned the old factions. One remnant followed Andrew Jackson and Martin Van Buren into the new Democratic Party by 1828. Another remnant, led by John Quincy Adams and Henry Clay, formed the National Republican Party in 1824 while some remaining smaller factions formed the Anti-Masonic Party, which along with some National Republican groups developed into the Whig Party by 1836. Most remaining National Republicans would soon after go on to be a part of the Free Soil and modern Republican parties in the 1840s and 1850s.Henry Clay
Henry Clay Sr. (April 12, 1777 – June 29, 1852) was an American attorney and statesman who represented Kentucky in both the United States Senate and United States House of Representatives, served as 7th speaker of the U.S. House of Representatives, and served as the 9th U.S. secretary of state. He received electoral votes for president in the 1824, 1832, and 1844 presidential elections and helped found both the National Republican Party and the Whig Party. For his role in defusing sectional crises, he earned the appellation of the "Great Compromiser."
Clay was born in Hanover County, Virginia in 1777 and launched a legal career in Lexington, Kentucky in 1797. As a member of the Democratic-Republican Party, Clay won election to the Kentucky state legislature in 1803 and to the U.S. House of Representatives in 1810. He was chosen as speaker of the House in early 1811 and, along with President James Madison, led the United States into the War of 1812 against Britain. In 1814, he helped negotiate the Treaty of Ghent, which brought an end to the War of 1812. After the war, Clay returned to his position as speaker of the House and developed the American System, which called for federal infrastructure investments, support for the national bank, and protective tariff rates. In 1820, he helped bring an end to a sectional crisis over slavery by leading the passage of the Missouri Compromise.
Clay finished with the fourth-most electoral votes in the multi-candidate 1824 presidential election, and he helped John Quincy Adams win the contingent election held to select the president. President Adams appointed Clay to the prestigious position of secretary of state; critics alleged that the two had agreed to a "corrupt bargain." Despite receiving support from Clay and other National Republicans, Adams was defeated by Democrat Andrew Jackson in the 1828 presidential election. Clay won election to the Senate in 1831 and ran as the National Republican nominee in the 1832 presidential election, but he was defeated by President Jackson. After the 1832 election, Clay helped bring an end to the Nullification Crisis by leading passage of the Tariff of 1833. During Jackson's second term, opponents of the president coalesced into the Whig Party, and Clay became a leading congressional Whig.
Clay sought the presidency in the 1840 election but was defeated at the Whig National Convention by William Henry Harrison. He clashed with Harrison's running mate and successor, John Tyler, who broke with Clay and other congressional Whigs after taking office in 1841. Clay resigned from the Senate in 1842 and won the 1844 Whig presidential nomination, but he was defeated in the general election by Democrat James K. Polk, who made the annexation of the Republic of Texas his key issue. Clay strongly criticized the subsequent Mexican–American War and sought the Whig presidential nomination in 1848, but was defeated by General Zachary Taylor. After returning to the Senate in 1849, Clay played a key role in passing the Compromise of 1850, which resolved a crisis over the status of slavery in the territories. Clay is generally regarded as one of the most important and influential political figures of his era.Kaolinite
Kaolinite () is a clay mineral, part of the group of industrial minerals, with the chemical composition Al2Si2O5(OH)4. It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO4) linked through oxygen atoms to one octahedral sheet of alumina (AlO6) octahedra. Rocks that are rich in kaolinite are known as kaolin or china clay.The name "kaolin" is derived from "Gaoling" (Chinese: 高嶺; pinyin: Gāolǐng; literally: "High Ridge"), a Chinese village near Jingdezhen in southeastern China's Jiangxi Province. The name entered English in 1727 from the French version of the word: kaolin, following François Xavier d'Entrecolles's reports on the making of Jingdezhen porcelain.Kaolinite has a low shrink–swell capacity and a low cation-exchange capacity (1–15 meq/100 g). It is a soft, earthy, usually white, mineral (dioctahedral phyllosilicate clay), produced by the chemical weathering of aluminium silicate minerals like feldspar. In many parts of the world it is colored pink-orange-red by iron oxide, giving it a distinct rust hue. Lighter concentrations yield white, yellow, or light orange colors. Alternating layers are sometimes found, as at Providence Canyon State Park in Georgia, United States. Commercial grades of kaolin are supplied and transported as dry powder, semi-dry noodle or as liquid slurry.Loam
Loam is soil composed mostly of sand (particle size > 63 µm), silt (particle size > 2 µm), and a smaller amount of clay (particle size < 2 µm). By weight, its mineral composition is about 40–40–20% concentration of sand-silt-clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the USDA textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and humus than sandy soils, have better drainage and infiltration of water and air than silt and clay-rich soils, and are easier to till than clay soils. The different types of loam soils each have slightly different characteristics, with some draining liquids more efficiently than others. The soil's texture, especially its ability to retain nutrients and water are crucial. Loam soil is suitable for growing most plant varieties.
Bricks made of loam, mud, sand, and water, with an added binding material such as rice husks or straw, have been used in construction since ancient times.Muhammad Ali
Muhammad Ali (; born Cassius Marcellus Clay Jr.; January 17, 1942 – June 3, 2016) was an American professional boxer, activist, and philanthropist. Nicknamed "The Greatest", he is widely regarded as one of the most significant and celebrated sports figures of the 20th century and one of the greatest boxers of all time.
He was born and raised in Louisville, Kentucky, and began training as an amateur boxer when he was 12 years old. At the age of 18, he won a gold medal in the light heavyweight division at the 1960 Summer Olympics in Rome, then turned professional later that year, before converting to Islam after 1961. At the age of 22, in 1964, he won the world heavyweight championship from Sonny Liston in a major upset. He then changed his name from Cassius Clay, which he called his "slave name", to Muhammad Ali. He set an example of racial pride for African Americans and resistance to white domination during the Civil Rights Movement.In 1966, two years after winning the heavyweight title, Ali further antagonized the white establishment by refusing to be drafted into the U.S. military, citing his religious beliefs, and opposition to American involvement in the Vietnam War. He was eventually arrested, found guilty of draft evasion charges, and stripped of his boxing titles. He successfully appealed the decision to the U.S. Supreme Court, which overturned his conviction in 1971, by which time he had not fought for nearly four years and thereby lost a period of peak performance as an athlete. Ali's actions as a conscientious objector to the war made him an icon for the larger counterculture generation.Ali was one of the leading heavyweight boxers of the 20th century, and remains the only three-time lineal champion of that division. His records of beating 21 boxers for the world heavyweight title (shared with Joe Louis), as well as winning 14 unified title bouts (shared with former welterweight champion José Napoles), were unbeaten for 35 years. Ali is the only boxer to be named The Ring magazine Fighter of the Year six times. He has been ranked the greatest heavyweight boxer of all time. He was also ranked as the greatest athlete of the 20th century by Sports Illustrated, the Sports Personality of the Century by the BBC, and the third greatest athlete of the 20th century by ESPN SportsCentury. Nicknamed "The Greatest", he was involved in several historic boxing matches. Notable among these were the Liston fights; the "Fight of the Century", "Super Fight II" and the "Thrilla in Manila" against his rival Joe Frazier; and The Rumble in the Jungle against George Foreman.
At a time when most fighters let their managers do the talking, Ali thrived in and indeed craved the spotlight, where he was often provocative and outlandish. He was known for trash-talking, and often freestyled with rhyme schemes and spoken word poetry, both for his trash-talking in boxing and as political poetry for his activism, anticipating elements of rap and hip hop music. As a musician, Ali recorded two spoken word albums and a rhythm and blues song, receiving two Grammy nominations. As an actor, he performed in several films and a Broadway musical. Ali wrote two autobiographies, one during and one after his boxing career.
As a Muslim, Ali was initially affiliated with Elijah Muhammad's Nation of Islam (NOI) and advocated their black separatist ideology. He later disavowed the NOI, adhering to Sunni Islam, practicing Sufism, and supporting racial integration, like his former mentor Malcolm X.
After retiring from boxing in 1981, at the age of 39, Ali focused on religion and charity. In 1984, he was diagnosed with Parkinson's syndrome, which some reports attribute to boxing-related injuries, though both Ali and his physician disputed the claim. As his condition worsened, Ali made limited public appearances, and was cared for by his family until his death on June 3, 2016, in Scottsdale, Arizona.National Register of Historic Places listings in Clay County, North Carolina

Pottery is the process of forming vessels and other objects with clay and other ceramic materials, which are fired to give them a hard, durable form. Major types include earthenware, stoneware and porcelain. The place where such wares are made by a potter is also called a pottery (plural "potteries"). The definition of pottery used by the American Society for Testing and Materials (ASTM), is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products." A different definition, used within the field of ceramics, is "everything which is not porcelain". In archaeology, especially of ancient and prehistoric periods, "pottery" often means vessels only, and figures etc. of the same material are called "terracottas". Clay as a part of the materials used is required by some definitions.
Pottery is one of the oldest human inventions, originating before the Neolithic period, with ceramic objects like the Gravettian culture Venus of Dolní Věstonice figurine discovered in the Czech Republic dating back to 29,000–25,000 BC, and pottery vessels that were discovered in Jiangxi, China, which date back to 18,000 BC. Early Neolithic pottery artefacts have been found in places such as Jōmon Japan (10,500 BC), the Russian Far East (14,000 BC), Sub-Saharan Africa and South America.
Pottery is made by forming a ceramic (often clay) body into objects of a required shape and heating them to high temperatures in a kiln which removes all the water from the clay, which induces reactions that lead to permanent changes including increasing their strength and hardening and setting their shape. A clay body can be decorated before or after firing; however, prior to some shaping processes, clay must be prepared. Kneading helps to ensure an even moisture content throughout the body. Air trapped within the clay body needs to be removed. This is called de-airing and can be accomplished either by a machine called a vacuum pug or manually by wedging. Wedging can also help produce an even moisture content. Once a clay body has been kneaded and de-aired or wedged, it is shaped by a variety of techniques. After it has been shaped, it is dried and then fired.Rafael Nadal
Rafael Nadal Parera (Catalan: [rəf(ə)ˈɛl nəˈðal pəˈɾeɾə], Spanish: [rafaˈel naˈðal paˈɾeɾa]; born 3 June 1986) is a Spanish professional tennis player, currently world No. 2 in men's singles tennis by the Association of Tennis Professionals (ATP).Nadal has won 17 Grand Slam singles titles, the second most in history for a male player, as well as a record 33 ATP World Tour Masters 1000 titles, 20 ATP World Tour 500 tournaments, and the 2008 Olympic gold medal in singles. In addition, Nadal has held the number one ranking for a total of 196 weeks. In majors, Nadal has won a record 11 French Open titles, three US Open titles, two Wimbledon titles, and one Australian Open title. Nadal has also won 57 clay court titles, including his 11 French Open titles, the most of any player in the Open Era. With 81 consecutive match wins on clay, Nadal has the longest single surface win streak of any player in the Open Era.
He was also a member of the winning Spain Davis Cup team in 2004, 2008, 2009, and 2011. In 2010, he became the seventh male player in history and youngest of five in the Open Era to achieve the Career Grand Slam at age 24. He is the second male player, after Andre Agassi, to complete the singles Career Golden Slam. In 2011, Nadal was named the Laureus World Sportsman of the Year.Soil
Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Earth's body of soil is the pedosphere, which has four important functions: it is a medium for plant growth; it is a means of water storage, supply and purification; it is a modifier of Earth's atmosphere; it is a habitat for organisms; all of which, in turn, modify the soil.
The pedosphere interfaces with the lithosphere, the hydrosphere, the atmosphere, and the biosphere. The term pedolith, used commonly to refer to the soil, translates to ground stone. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soils are often treated as a three-state system of solids, liquids, and gases.Soil is a product of the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and its parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, it is considered an ecosystem by soil ecologists.Most soils have a dry bulk density (density of soil taking into account voids when dry) between 1.1 and 1.6 g/cm3, while the soil particle density is much higher, in the range of 2.6 to 2.7 g/cm3. Little of the soil of planet Earth is older than the Pleistocene and none is older than the Cenozoic, although fossilized soils are preserved from as far back as the Archean.Soil science has two basic branches of study: edaphology and pedology. Edaphology is concerned with the influence of soils on living things. Pedology is focused on the formation, description (morphology), and classification of soils in their natural environment. In engineering terms, soil is included in the broader concept of regolith, which also includes other loose material that lies above the bedrock, as can be found on the Moon and other celestial objects, as well. Soil is also commonly referred to as earth or dirt; some scientific definitions distinguish dirt from soil by restricting the former term specifically to the displaced soil.Tennis court
A tennis court is the venue where the sport of tennis is played. It is a firm rectangular surface with a low net stretched across the center. The same surface can be used to play both doubles and singles matches. A variety of surfaces can be used to create a tennis court, each with its own characteristics which affect the playing style of the game.Terracotta Army
The Terracotta Army is a collection of terracotta sculptures depicting the armies of Qin Shi Huang, the first Emperor of China. It is a form of funerary art buried with the emperor in 210–209 BCE with the purpose of protecting the emperor in his afterlife.
The figures, dating from approximately the late third century BCE, were discovered in 1974 by local farmers in Lintong District, Xi'an, People's Republic of China, Shaanxi province. The figures vary in height according to their roles, with the tallest being the generals. The figures include warriors, chariots and horses. Estimates from 2007 were that the three pits containing the Terracotta Army held more than 8,000 soldiers, 130 chariots with 520 horses, and 150 cavalry horses, the majority of which remained buried in the pits near Qin Shi Huang's mausoleum. Other terracotta non-military figures were found in other pits, including officials, acrobats, strongmen, and musicians.Tyrus (wrestler)
