Geysers

Geysers are natural hot springs that spray water and steam into the air at regular or irregular intervals. They form in areas where underground water is heated by magma close to Earth's surface. When this water becomes superheated, it expands and bursts out through narrow passages in the ground. Geysers are rare an...

In some places, water doesn’t just flow; it erupts. These rare geological features are called geysers. Geysers form when heated groundwater becomes trapped in rock. As pressure builds, the water erupts through a crack in the ground.

Below the surface, magma heats this trapped water until it becomes extremely hot. The water can’t boil becau...
