Geyser, an Unique Nature Phenomena
A geyser is the result of
underground water under the combined conditions of high
temperatures and
increased pressure beneath the surface of the earth. Since temperature rises
approximately 1° F for every sixty feet under the earth’s surface, and pressure
increases with depth, the water that seeps down in crack and fissures until it
reaches very hot rock in the earth interior becomes heated to temperature in
excess of 290° F. because of the greater pressure, the water shoots out of the
surface in the form of steam and hot water. The result is a geyser, in order to
function, then a geyser must have a source of heat, reservoir where water can
be stored until the temperature rises to an unstable point, an opening through which
the hot water and steam can escape, and underground channels for resupplying
water after an eruption.
Favorable conditions for geyser exist in some regions of the world
including New Zealand, Iceland, and the Yellowstone National Park area of the
United States. The almost every hour, rising to a height of 125 to 170 feet and
expelling more than ten thousand gallons during each eruption.
