Geyser

Geyser is a kind of hot springs that burst periodically, removing the hot water and steam into the air. The name geyser comes from Geysir in Haukadalur, Iceland. The word became a verb gjósa Icelandic language, "gush".

Geyser formation depends on the specific hydrogeological conditions are found only in a few places on Earth, and therefore Geysers is a rare phenomenon. About 1000 exist around the world, about half of Yellowstone National Park, USA. Bursts of activity of the geysers may stop due to precipitation of minerals in the geysers, earthquakes, and human intervention.

Ejection of liquid nitrogen has been observed on the moon of Neptune, Triton. In addition at the south pole of Mars is covered with ice, there is the possibility of carbon dioxide sembuaran. This phenomenon is also often called the Geysers, but not caused by geothermal energy, but heating by the sun and the greenhouse effect. On Triton, the nitrogen can be sprayed with a height of 8 km.
