Geothermal Energy Notes

• Geothermal energy-is heat deep underground that can produce electricity
• We will never run out of geothermal energy because it is a renewable energy source
• Geothermal energy is everywhere underground
• Geothermal energy has been used for thousands of years
• The electricity geothermal energy uses is called geothermal power
• Power plants make electrical power by using energy
• The word geothermal comes from the words geo meaning Earth and therme meaning heat
• Gethermal energy is a renewable energy source because the heat is continuosly making this energy in the Earth
• Magma from the core comes up to the Earth's crust,this is how a volcanoe happens
• The Earth's crust is in broken pieces called plates
• Geothermal resvoirs are usually deep underground with no clues that show above ground
• Geothermal energy can come up in the form of a volcanoe,furmarole,geyser,and hot spring
• Gethermal activity usually occurs in an area called the "Ring of Fire"
• Hydrothermal happens when magma comes close to the Earth's surface and heats the ground water that is trapped in porous rock
• There are three types of power plants called Dry Steam Plants,Flash Steam Plants,and Binary Cycle Power
• Geothermal energy doesn't pollute the Earth which makes it better for the enviorment
