Three surfaces on which Tennis is played

There are five types of court surface used in professional play. Each surface is different in the speed and height of the bounce of the ball. The same surface plays faster indoors than outdoors.

Clay	Examples are red clay (used at the French Open and many other tournaments, especially in Europe and Latin America) and green clay (an example of which is Har-Tru and used mainly in the U.S.). Clay courts normally have a slower paced ball and a fairly true bounce with more spin.
Hard	Examples are acrylic (e.g. Plexicushion used at the Australian Open, DecoTurf used at the US Open), asphalt, and concrete. Hardcourts typically have a faster-paced ball with a very true bounce.
Grass	Used at Wimbledon. Grass courts usually have a faster-paced ball, and a more erratic bounce. Wimbledon has slowed its courts over the years.
