Court surfaces refer to the materials used to create the playing area for various sports, such as tennis, basketball, and volleyball. Different surfaces can affect the speed and bounce of the ball, influencing gameplay. Common types include hard courts, made of asphalt or concrete, clay courts, which are composed of crushed brick or stone, and grass courts, known for their natural turf. Each surface has its own characteristics. For example, hard courts provide a consistent bounce and are often used in professional tournaments like the US Open. In contrast, clay courts slow down the ball and allow for longer rallies, while grass courts offer a faster game with a lower bounce.
