A chapter from the book "Water" is presented. It discusses the sources of water that can be found beneath the Earth's surface. It notes that 25 percent of Earth's fresh water flows underground to form wells and springs. It explains that the level of Earth's ground water rises and falls with the seasons. The chapter also mentions how caves, stalactites, and stalagmites are formed by streams of acidic rainwater that flow underground.
