GEYSER
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 degree F for every sixty feet under the earth’s surface, and pressure increases with depth, water that seeps down in cracks and fissures until it reaches very hot rocks in the earth’ interior becomes heated to temperature in excess of 290 degree F. Because of the greater pressure, it 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 re-supplying water after an eruption.
Favorable conditions for geyser exits in regions of the world : New Zealand, Iceland, and the Yellowstone National Park area of the United States. The most famous geyser in the world is Old Faithful in Yellow Park. Old Faithful erupts almost every hour, rising to a height of 125 to 170 feet and expelling more than ten thousand gallons during each eruption.

BalasHapusThe formation of geysers is due to particular hydrogeological conditions, which exist in only a few places on Earth, so they are a fairly rare phenomenon. Generally all geyser field sites are located near active volcanic areas, and the geyser effect is due to the proximity of magma. Generally, surface water works its way down to an average depth of around 2,000 metres (6,600 ft) where it contacts hot rocks. The resultant boiling of the pressurized water results in the geyser effect of hot water and steam spraying out of the geyser's surface vent (a hydrothermal explosion).
