Earth Science - Geology - Learning Points. Caves are natural underground holes carved by water. Sea caves are formed by the power of the ocean. Acidic rainwater dissolves limestone to form caverns. Stalactites are formed as chemical-rich water deposits calcium carbonate that runs through the rock and from the roof. Stalagmites are formed as calcium carbonate collects on the ground. A Twig Context Film. Reinforce and extend the learning required by the curriculum. Twig’s context films show abstract concepts in action in the real world.\n
