What are Geysers and how are they formed

A geyser is a hot spring that periodically erupts, throwing water into the air. Generally all geyser field sites are located near active volcanic areas. Their formation requires the combination of 3 specific geologic conditions that are usually found in volcanic terrain: 1- heat, 2- water, 3- a plumbing system. Superheated water is needed in order for geysers to form. The heat comes from a buried magma chamber in a volcanic setting. Water is more easily obtained than the heat. The water comes from the groundwater system in the geyser basin. In order for the heated water to form a geyser basin. In order for the heated water to form a geyser a plumbing system is needed. This includes a reservoir to hold the water while it is heated. The geyser plumbing system is probably formed by a combination of spots of porous rock.
