Question

Heat energy obtained from the earth is called ________

Answer 1

Hint: Energy is the quantitative property that must be transferred to a body or physical system to perform work on it or to heat it, according to physics. Energy is a conserved quantity, meaning it can be converted in form but not created or destroyed, according to the law of conservation of energy.

Complete answer:
Heat energy exists in all matter. Heat energy is produced by the movement of minute particles known as atoms, molecules, or ions in liquids, solids, and gases. Heat energy can be transferred from one substance to another, and heat is defined as the flow of energy caused by a temperature difference between two objects.
Geothermal energy is the heat energy derived from the earth's interior and hot rocks. Geothermal energy is the thermal energy in the Earth's crust that comes from both the planet's formation and the radioactive decay of materials in currently unknown but possibly roughly equal proportions.
Geothermal heating, such as using hot spring water for bathing, has been used for bathing since Paleolithic times and space heating since ancient Roman times, but geothermal power, the term for the generation of electricity from geothermal energy, has recently gained in popularity.
The earth's geothermal resources are estimated to be more than sufficient to meet humanity's energy needs, though only a small fraction is currently profitably exploited, often in areas near tectonic plate boundaries.
Thus, Heat energy obtained from the earth is called Geothermal energy.

Note:
Magma heats nearby rocks and aquifers underground. Geysers, hot springs, steam vents, underwater hydrothermal vents, and mud pots can all release hot water. All of these are geothermal energy sources. Their heat can be captured and used to generate electricity, or their steam can be used to generate electricity.
