It bounces up for the same reason it hurts your hand when you punch a wall. It is a law of physics that for every action there is an equal and opposite reaction. With your hand, the force used to punch the wall comes back and hits you right in the fist. With the ball, the force comes back and shoots the ball back up again. This may make you wonder, why doesn't your hand bounce off the wall. That is because of elasticity and the fact that the Basketball is hollow. The material in the ball can stretch to allow it to bounce. Your hand is solid and has non-stretching bone inside.
