SOLAR SYSTEM

Detailed explanation-1: -Geothermal heat in deep-sea vents and on land provides energy for unique ecosystems with organisms that evolved to live in these areas. Heat inside the Earth from radioactive decay of elements and residual heat leftover from Earth’s formation. This heat drives plate tectonics and parts of the rock cycle.

Detailed explanation-2: -Sources of heat About 50% of the Earth’s internal heat originates from radioactive decay. Four radioactive isotopes are responsible for the majority of radiogenic heat because of their enrichment relative to other radioactive isotopes: uranium-238 (238U), uranium-235 (235U), thorium-232 (232Th), and potassium-40 (40K).

Detailed explanation-3: -Many of the rocks in Earth’s crust and interior undergo this process of radioactive decay . This process produces subatomic particles that zip away, and later collide with surrounding material inside the Earth. Their energy of motion is converted to heat.

Detailed explanation-4: -There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.
