Description: Portrays the function of underground water in producing geysers and caverns. Utilizes animation to illustrate underground water, the water table, movement of underground water, re-entrance of underground water on the surface (springs), and re-entrance of water below the level of the underground water (lakes). Discusses the work of water in producing stalactites, stalagmites, columns, cave pearls, helictites, rimstone, curtains, and flowstones in caverns. Uses animation to show the water cycle for the eruption of geysers., Illustrates how underground water is constantly changing our earth: dissolving limestone to form caverns, volcanic heating to cause hot springs and geysers. Shows how geothermal energy may help us in the future.
