Geyser field. Steam rising from hot pools in a geyser field. Geysers are deep natural wells in geothermal rock fissures. Their water lies in a large chamber at the well's base. The water is heated by surrounding rocks until it is well over its normal boiling point,but is prevented from boiling by hydrostatic pressure. At a critical temperature,the superheated water spontaneously boils,causing an eruption. Photographed in Chile | |
