Geothermal Heat

Geothermal heat refers to the heat energy that is generated and stored within the Earth. This heat is derived from the radioactive decay of minerals, as well as from the original formation of the planet. It manifests itself in various forms, including geysers, hot springs, and volcanoes. Geothermal energy can be harnessed for various purposes, such as electricity generation, heating, and industrial processes.

Key Concepts

1. Geothermal Energy: The heat energy stored within the Earth that can be harnessed for human use.
2. Geothermal Gradient: The rate at which temperature increases with depth within the Earth's crust.
3. Geothermal Resources: Natural reservoirs of steam, hot water, and hot rocks that can be utilized for energy production.
4. Geothermal Power Plants: Facilities that convert geothermal energy into electricity.
5. Geothermal Heating Systems: Utilize geothermal energy to heat buildings and water.
