Clay Court
A clay court is one of the types of tennis court on which the sport of tennis, originally known as "lawn tennis", is played. Clay courts are made of crushed stone, brick, shale, or other unbound mineral aggregate depending on the tournament. The French Open uses clay courts, the only Grand Slam tournament to do so. Clay courts are more common in Continental Europe and Latin America than in North America, Asia-Pacific 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. Play Clay courts are considered "slow" because the balls bounce relatively high and lose much of their initial speed when contacting the surface, making it more difficult for a player to deliver an unreturnable shot. Points are usually longer as there are fewer winners ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topspin
In ball sports, topspin or overspin is a property of a ball that rotates forwards as it is moving. Topspin on a ball propelled through the air imparts a downward force that causes the ball to drop, due to its interaction with the air (see Magnus effect). Topspin is the opposite of backspin. Baseball In baseball, the curveball, a type of pitch which usually has downward movement, is thrown in such a way as to put topspin on the ball. Its close relatives are the slider and the slurve. The "curve" of the ball varies from pitcher to pitcher. Cue sports In snooker, pocket billiards and billiards, players use topspin to keep the cue ball moving, including after it hits other balls. They get top spin by hitting the cue against the top of the ball. Cricket In cricket, a top-spinner is a type of delivery bowled by a cricketer bowling either wrist spin or finger spin. In either case, the bowler imparts the ball with top spin by twisting it with his or her fingers prior to delivery. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Hard Court Championships
World Hard Court Championships was an annual major tennis tournament sanctioned by the International Lawn Tennis Federation and held from 1912 to 1923. It was principally held in Paris, on clay courts of the Stade Français in the Paris suburb of Saint-Cloud, with one exception when they were held at the Royal Leopold Club in Brussels, Belgium, in 1922. The name of the event referred to its venues that were surfaced with clay, which at the time was customarily transcribed as "hard court" in English. It was open to all international amateur players from all nationalities, unlike the French Championships, which were open only to tennis players who were members of clubs in France through 1924; because of this the World Hard Court Championships is sometimes considered as the proper precursor to the French Open. The French Championships were also held at a different venue at the time, the Racing Club de France, Paris. At an annual general meeting held on 16 March 1923 in Paris, France ...

US Men's Clay Court Championships
The U.S. Men's Clay Court Championships is an annual ATP Tour tennis tournament that started in 1910. It is the last remaining ATP World Tour-level tournament in the United States to be played on clay courts. The tournament began in 1910 when the Western Lawn Tennis Association (a section of the United States Lawn Tennis Association now known as the USTA/Midwest) lobbied the USLTA that a National Clay Court Championship would help promote the establishment of more clay courts in the West. Clay courts were more economical to install and maintain than grass courts, and the hope was that the lower costs associated with court construction would allow for a more rapid expansion of the game. The first National Clay Court Championships were held at the Omaha Field Club with a crowd of 5,000 watching the finals. Participation and play on clay grew as a result of the event and others, and in 1914 the event was moved to the Cincinnati Tennis Club. It has since been played in numerous cities, ...

Amphibolite
Amphibolite () is a metamorphic rock that contains amphibole, especially hornblende and actinolite, as well as plagioclase feldspar, but with little or no quartz. It is typically dark-colored and dense, with a weakly foliated or schistose (flaky) structure. The small flakes of black and white in the rock often give it a salt-and-pepper appearance. Amphibolite frequently forms by metamorphism of mafic igneous rocks, such as basalt. However, because metamorphism creates minerals entirely based upon the chemistry of the protolith, certain 'dirty marls' and volcanic sediments may also metamorphose to an amphibolite assemblage. Deposits containing dolomite and siderite also readily yield amphibolite (tremolite-schist, grunerite-schist, and others) especially where there has been a certain amount of contact metamorphism by adjacent granitic masses. Metamorphosed basalt (metabasalt) creates ''ortho-amphibolite'' and other chemically appropriate lithologies create ''para-amphibolite''. ...
