Unformatted text preview: Geosciences Unit 2 Plate Tectonics I, Yelowstone Yellostone is Shaking evidence indicates that there is a body of melted rock under the park the rocks are anomalously hot at shallow depth park recieves an abundant rainfall and snowfall the water circulates deeply through rocks broken by numerous earthquakes, and he water is heated from below in some places, the water is heated all the way to steam and emerges from holes (fumaroles) hot water bubbles to springs if the bubbling mixes in enough mud, then mud volcanoes develop at times, cold colder on the top holds the water down putting pressure preventing boiling eventually the boiling manages to get rid of the water above, reducing the pressure, which causes more boiling, causing a geyser to erupt these geysers require heat, water, and a tight plubing system to hold the hot water and withstand the high pressures the volcanic rocks are rich of silica, which is dissolved and re-precipitated by the hot waters...
