More than 80 percent of the earth's surface originated from volcanoes. The 16th lesson in a 20-part series introduces the shape and development of volcanoes. It begins with a demonstration using a balloon and flour to illustrate the development of caldera. To finish, scholars use pudding and jello to show the movement of magma as it erupts onto the surface.
