GEOLOGY

Detailed explanation-1: -These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly. Geothermal energy has been used for thousands of years in some countries for cooking and heating. It is simply power derived from the Earth’s internal heat.

Detailed explanation-2: -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. Their heat can be captured and used directly for heat, or their steam can be used to generate electricity.

Detailed explanation-3: -Geothermal energy comes from deep inside the earth An outer core of hot molten rock called magma that is about 1, 500 miles thick. A mantle of magma and rock surrounding the outer core that is about 1, 800 miles thick.

Detailed explanation-4: -Geothermal power plants draw fluids from underground reservoirs to the surface to produce steam. This steam then drives turbines that generate electricity. There are three main types of geothermal power plant technologies: dry steam, flash steam, and binary cycle.

Detailed explanation-5: -Geothermal energy is heat energy from the earth-Geo (earth) + thermal (heat). Geothermal resources are reservoirs of hot water that exist or are human made at varying temperatures and depths below the Earth’s surface.
