Answer 1

Answer:

You've probably seen or heard of lava flows, geysers, fumaroles, and hot springs. These are natural displays of geothermal energy. For example, hot springs are heated by geothermal heat. When water comes into contact with hot rocks deep in the Earth's crust, it can rise to the surface to form springs.
