Question

Geothermal energy is the thermal energy present ______________.
A. On the surface of the earth
B. In the interior of the earth
C. On the surface of the ocean
D. None of these

Answer 1

Hint:- Geothermal energy is a type of energy transfer in which heat energy is collected and harnessed from within the Earth for cooking, bathing, space heating, producing electricity, and other uses.

Complete answer:
Heat produces surface phenomena from the interior of the Earth, such as lava flows, geysers, fumaroles, hot springs, and mud pots. The heat is produced primarily by the radioactive oxidation of potassium, thorium, and uranium in the crust and mantle of the Earth, as well as by friction along the margins of continental plates. The resulting low-grade annual heat transfer to the surface worldwide averages between 50 and 70 milliwatts (mW) per square meter.
Geothermal energy refers to the heat and electricity produced from the Earth's interior by the use of heat. Geothermal energy refers to the heat and electricity produced from the Earth's interior by the use of heat. Groundwater absorbs heat from the rocks in such areas and becomes hot. It is so hot that it converts into steam as it comes to the surface of the planet. To drive turbines and produce electricity, this steam is used.

Therefore the correct option is (b) In the interior of the earth.

Note :- The oldest method of geothermal technology is dry steam, which takes the steam out of the ground and uses it to drive a turbine directly. Although binary plants move hot water into a second liquid with a lower boiling point, which transforms to vapor to drive the turbine, flash plants use high-pressure hot water in cold, low-pressure water.
