explain geothermal?

Question

explain

Answer 1

geo= earth
thermal = heat or energy

so geothermal is energy from the earth, like Old Faithful

Answer 2

Geothermal is a name used to describe an energy supply that is taken from geological formations. That is, deep underground there are pockets of trapped liquid, that because of the pressure and depth the liquids are very hot. This geothermal energy can be extracted by drilling into the formation and taking the hot underground water (known as brine) and using this hot brine to heat water to produce steam. It is not generally used directly, because the brine is very corrosive, but if the metallurgy is designed correctly you can use the hot brine directly by letting it come out of the ground to a lower pressure and thus produce steam which in turn is used to drive turbins in electric generators.

Again remember geo means geological formations, and thermal means heat energy.

Answer 3

Geothermal usually refers to hot water coming out of the ground, which happens in some places. Heat is always being produced inside the earth by slow radioactive decay, but near the surface the heat doesn't stick around. It radiates into the atmosphere and into space.

Answer 4

Utilizing the heat produced from hot springs ,volcanoes and geysers to produce electricity for the community or an industry in the vicinity of such geothermal source.
