"Water that lurks beneath the Earths surface is usually far easier to ignore than the water that covers it, until that water bursts forth above ground as geysers and hot springs. This ... volume explains to young readers where this water comes from and its relationship to volcanic activity underground. They will also learn where on Earth these spectacular eruptions are found, how geothermal energy can be harnessed for our use, and much more"--Amazon.com.

Explores the nature, location, and causes of hot springs, including those that gush hot water and steam into the air and are called geysers.
