Igneous Landforms and Geothermal Activity
... Geysers are also created by water that is heated beneath the Earth’s surface. The water may become superheated by magma. It becomes trapped in a narrow passageway. The heat and pressure build as more water is added. When the pressure is too much, the superheated water bursts out onto the surface. Th ...
