Today in English For IT II I learned a lot about Geyser and the following is a summary of the material I’ve learned :
A geyser is a result of underground water temperature rose about 1 ° F for every sixty feet below the surface of the Earth, and increasing pressure with depth is very hot in the interior of the Earth to about 290 ° F.
but the geysers, the weight of water near the surface pressure over the geyser reaches higher temperatures than water at the top.
Favorable conditions for the fountain in the area geologically recent volcanic activity, especially in areas of more than average rainfall. For the most part, the geysers in the three regions of the world: New Zealand, Iceland, and Yellowstone National Park area the United States. The world’s most famous geyser is Old Faithful in Yellowstone Park. Old Faithful erupts every hour, up to a height of 125-170 feet,
unlike most geysers, never fails to erupt on schedule even once in eight years of observation.
As the water becomes warmer, lighter and consequently, a sudden rise to the surface and bud out from the surface in the form of steam and hot water. In the end create more explosions. Soon after, the water flows back into the underground reservoir, heating begins, and the process repeated. To function, then, the geyser must have a heat source, a reservoir where water can be stored until the temperature rises to a stable point.
