The correct answer is: Geothermal energy.
Geothermal energy is the heat energy generated within the Earth. It is a form of renewable energy that can be used to generate electricity, heat homes and businesses, and provide hot water.
Geothermal energy is produced by the decay of radioactive elements in the Earth’s core. This decay releases heat, which travels through the Earth’s crust and mantle. The heat can be tapped at various depths, depending on the location.
Geothermal energy is a clean and sustainable form of energy. It does not produce greenhouse gases or other pollutants. It is also a reliable source of energy, as it is not affected by the weather.
Geothermal energy is a promising source of energy for the future. It has the potential to meet a significant portion of the world’s energy needs.
The other options are incorrect because they do not describe the energy stored within the earth.
- Mechanical energy is the energy of motion. It is the energy that is possessed by an object due to its motion.
- Wind energy is the energy of the wind. It is the energy that is possessed by the wind due to its motion.
- Thermal energy is the energy of heat. It is the energy that is possessed by an object due to its temperature.
