Geyser Gazing

What Causes a Geyser?

A geyser is caused by water on the surface of the Earth seeping down toward the center of the Earth where it contacts magma-heated rock that causes it to boil and erupt back up to the Earth’s surface by the process of convection. A tremendous
column of a geyser eruption is often the result of the process which repeats itself over and over again through the geyser’s vent.
