Because the hard surface doesn't absorb any of the energy of the tennis ball - thus the ball bounces higher than if it was dropped on a softer surface.

A tennis ball bounces higher on harder surfaces because hard surfaces are less able to absorb the energy of the ball when it hits, resulting in more of the ball's energy being converted directly into upward motion. Softer surfaces absorb more of the energy, causing the ball to bounce lower.
Tennis balls bounce higher depending on factors like their internal pressure, felt quality, and core material. New balls with higher pressure and less wear will bounce higher compared to older balls with lower pressure and more wear. The type of surface and conditions where the ball is being used can also affect its bounce height.
A tennis ball is made of materials that are more elastic than a basketball, allowing it to deform and rebound quicker upon impact, resulting in a higher bounce. Additionally, the size and weight difference between a tennis ball and a basketball also contribute to the tennis ball bouncing higher.
New tennis balls bounce higher than old tennis balls because they have more elasticity and air pressure which allows them to compress and decompress more easily upon impact with the ground. As tennis balls are used, the felt covering wears out and the air inside the ball escapes, leading to less bounce.
A tennis ball is larger and lighter than a golf ball, allowing it to store and release more kinetic energy upon impact with the ground. This results in a higher bounce compared to a denser and heavier golf ball that absorbs more of the impact energy.
The temperature of a tennis ball can affect its bounce height. As temperature increases, the air molecules inside the ball expand, causing it to bounce higher. Conversely, at lower temperatures, the ball may not bounce as high due to decreased air pressure.
