Beakman's World: Cave Formation
00:12:10 - 00:19:54
Beakman explains how caves are formed by acid dissolving limestone and he uses a model to show how this happens. He explains there are two major sections of a cave called the twilight zone (little light reaches in) and the dark zone (no light reaches). Beakman describes the different animals that live there and their features. They also talk about stalagmites and stalagtites and then make their own.
