Geysers


Geysers are jets of boiling water and steam that erupt from beneath the ground where water is heated by volcanic activity. The name geysers comes from a hot spring called Geysir at Haukadalur ,Iceland. Yellowstone National Park,Wyoming, USA has more geysers than anywhere else. There are 500 active ones including Steamboat geyser, which erupts to a height of 120m and old faithful geyser which erupts about every 91 minute.
