What is Geothermal energy?
Answers
Answer: What is geothermal energy?
Geothermal energy is heat within the earth. The word geothermal comes from the Greek words geo (earth) and therme (heat). Geothermal energy is a renewable energy source because heat is continuously produced inside the earth. People use geothermal heat for bathing, to heat buildings, and to generate electricity.
Geothermal energy comes from deep inside the earth
Image of the earth's interior, from the outside to the inside, with the crust, the mantle of magma and rock, the outer core of magma, and the innermost core of iron.
The slow decay of radioactive particles in the earth's core, a process that happens in all rocks, produces geothermal energy.
The earth has four major parts or layers:
An inner core of solid iron that is about 1,500 miles in diameter
An outer core of hot molten rock called magma that is about 1,500 miles thick.
A mantle of magma and rock surrounding the outer core that is about 1,800 miles thick
A crust of solid rock that forms the continents and ocean floors that is 15 to 35 miles thick under the continents and 3 to 5 miles thick under the oceans
The earth's crust is broken into pieces called tectonic plates. Magma comes close to the earth's surface near the edges of these plates, which is where many volcanoes occur. The lava that erupts from volcanoes is partly magma. Rocks and water absorb heat from magma deep underground.
Answer:
Geothermal energy is energy generated and stored in earth... The adjective geothermal energy orgnitics from the Greek . Earth internal heat is thermal energy generated from radioactive decy and continue heat loss from earth's information.......
