Geothermal energy is used to supply heat for industrial purposes. It may also be used to promote agricultural and aquaculture production in cold climates by heating soils, aquaculture ponds and greenhouses. In addition, high-temperature geothermal energy is used to generate electricity.Continue Reading
Geothermal energy has been used for many years in various parts of the world for cooking and heating. Since time immemorial, humankind has utilized the geothermal energy that flows freely from underground reservoirs to the Earth’s surface. For instance, geothermal water was used by the Romans to treat different kinds of diseases, and to heat the city of Pompeii. For more than 10,000 years, the indigenous North Americans used geothermal water for cooking, as well as for medicinal purposes. Geothermal springs have been used for washing and bathing in Iceland. Modern uses of geothermal energy includes heating and cooling of buildings. This is achieved through the use of geothermal pumps that make use of shallow resources. Geothermal energy is also used to directly heat structures.
The word “geothermal” is derived from two Greek words: “geo” which means "Earth" and “thermal” which means "heat." Geothermal energy is a source of power derived from the Earth’s internal heat. It is contained within the rocks and fluids beneath Earth’s crust. Geothermal energy may be obtained anywhere from shallow ground to several miles beneath the surface. Other renewable energy sources include wind, wave, biomass and solar power.Learn more about Earth Science
Earth's climate is determined by the amount of incoming solar radiation that reaches the planet and the amount of reflected heat energy that radiates back into space. There are also a number of lesser factors that affect the average weather conditions that compose the various regional climates found across the globe.Full Answer >
Geothermal energy is derived from the heat naturally emitted from the Earth's interior. This form of energy may be harnessed from underground steam and water sources and heat from solid rock and magma. It is a renewable energy source that may be used in many applications instead of fossil fuels.Full Answer >
Thermal energy moves from one object to another through heat energy. Heat energy moves through convection, conduction and radiation. The internal movement of atoms generates energy in matter. As the temperature of matter increases, the internal movement also increases.Full Answer >
The sun provides the Earth with energy in the form of heat, which it uses to warm the Earth's surface, oceans and atmosphere. The heat energy found in the atmosphere is one of the major components of the Earth's climate and climate change, according to Windows to the Universe.Full Answer >
