Energy derived from the heat within the earth is known as?

The energy derived from the heat within the Earth is known as geothermal energy. This form of energy is harnessed from the natural heat that is present in the Earth's crust. It can be generated by tapping into hot springs, steam vents, or by drilling deep wells to access the high temperatures found several kilometers underground. Geothermal energy is a renewable resource as it relies on the Earth's internal heat, making it a sustainable option for generating electricity and providing direct heating.

In contrast, solar power involves converting sunlight into electricity or heat. Hydraulic energy refers to energy generated by the movement of water, typically through dams or rivers, while tidal power harnesses energy from the gravitational pull between the Earth, moon, and sun, creating tides in ocean bodies. These alternate energy sources do not derive energy from the Earth's internal heat, distinguishing them from geothermal energy.
