Detailed explanation-1: -Hot springs are heated by geothermal heat-heat from the Earth’s interior. In volcanic areas, water may come into contact with very hot rock heated by magma.
Detailed explanation-2: -Geothermal energy exists in all rocks deep in the earth’s crust. Hot igneous rock at moderately shallow deptlis makes it possible to utilize geothermal energy because these bodies bring high temperatures within reach of the drill.
Detailed explanation-3: -What makes a geyser erupt? Water percolating down from above is warmed by geothermal heat from below, forming pressurized steam in an underground cavity. The high pressure causes the water to become superheated above its usual boiling point of 212 degrees F (100 degrees C).
Detailed explanation-4: -Origin of Hot Springs Hot springs develop when rain and melted snow waters infiltrate into the ground. This ground water then sinks deep into the earth and is warmed by the heat contained in the earth’s interior.
Detailed explanation-5: -Geothermal power plants use hot water to generate steam to turn a turbine for electricity generation. Since the heat of the water is the essential component of a geothermal power plant, these active systems are typically located where hydrothermal reservoirs exist.
