GEOLOGY

Detailed explanation-1: -hot spring, also called thermal spring, spring with water at temperatures substantially higher than the air temperature of the surrounding region. Most hot springs discharge groundwater that is heated by shallow intrusions of magma (molten rock) in volcanic areas.

Detailed explanation-2: -A hot spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma (molten rock) or by circulation through faults to hot rock deep in the Earth’s crust.

Detailed explanation-3: -Magma heats nearby rocks and underground aquifers. Hot water can be released through geysers, hot springs, steam vents, underwater hydrothermal vents, and mud pots. These are all sources of geothermal energy.

Detailed explanation-4: -Water heated below ground that rises through a crack to the surface creates a hot spring.

Detailed explanation-5: -When magma heats groundwater, it may come to the surface as a hot spring or a geyser. Geysers erupt because the water is trapped. The water becomes superheated until finally the pressure builds enough for it to break the seal. Yellowstone is famous for its geysers.
