Geysers Eric Angat teacher

What is a Geyser? A geyser is a vent in Earth's surface that periodically ejects a column of hot water and steam. Even a small geyser is an amazing phenomenon; however some geysers have eruptions that blast thousands of gallons of boiling hot water up to a few hundred feet in the air. Old Faithful is the world's best known geyser. It is located in Yellowstone National Park (USA). Old Faithful erupts every 60 to 90 minutes and blasts a few thousand gallons of boiling hot water between 100 and 200 feet into the air.

Countries With Many Active Geysers 1)United States – Yellowstone National Park 2) Russia - Dolina Geiserov 3) Chile - El Tatio 4) New Zealand - Taupo Volcanic Zone 5) Iceland - Many locations
