A:
Energy harvest from coal
B:
Energy harvest from petroleum
C:
Energy harvest from thermal plants
D:
Energy harvest from natural heat produced in the earth
Explanation
The correct answer is (D) Energy harvest from natural heat produced in the earth.
Geothermal energy refers to the utilization of the natural heat generated within the Earth's crust. It involves extracting heat from hot rocks, magma, or geothermal reservoirs deep beneath the Earth's surface. This heat can be harnessed for various purposes, such as generating electricity or providing heating and cooling for buildings.
Unlike options (A) Energy harvest from coal, (B) Energy harvest from petroleum, and (C) Energy harvest from thermal plants, geothermal energy is not derived from fossil fuels or thermal plants, but rather from the Earth's internal heat sources.
