What was not a source of heat for early earth?
One source of heat for early Earth that is not considered likely is nuclear fission, as it requires very specific conditions and materials. Other sources of heat for early Earth include primordial heat from the planet's formation and the decay of radioactive elements.
What is the source of heat in the mantle?
The source of heat in the mantle primarily comes from the decay of radioactive elements like uranium, thorium, and potassium. This process releases energy in the form of heat which contributes to the high temperatures within the Earth's mantle.
Is the sun the heat source for the convection currents in the mantle?
The heat in the Earth's interior comes from two main sources: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust and the primordial heat left over from the formation of the Earth.
What is the source of earths internal heat?
Oh, honey, the Earth's internal heat comes from a combination of radioactive decay, residual heat from when the planet formed billions of years ago, and a sprinkle of leftover energy from all those fiery collisions during its early days. So, yeah, it's basically a hot mess down there, but that's what keeps things interesting on the surface.
What is the heat source that drives convection current Inside earth?
The heat source that drives convection currents inside the Earth is primarily from the decay of radioactive elements within the Earth's core. This heat causes the material in the mantle to become less dense and rise, creating convection currents that drive the movement of tectonic plates.

What are the two main sources from within the earth?
The most important source of heat from within the earth comes from the decay of radioactive isotopes, such as those of Uranium, Thorium and Potassium. It contributes approximately 75-90% of all heat that reaches the surface. The second source of heat is secular cooling. This "primordial" heat was formed in the early history of Earth by accretion and differentiation, and in fact, is still being generated by the gravitational partitioning of iron in the core. It accounts for ~10-15% of heat that reaches the surface.
What is the internal heat of the earth?
The source of the Earth's internal heat is a result of gravitational compression and to a much lesser extent, the decay of radioactive isotopes.The heat present in the Earth is due to several factors.The first source of heat is from the remnants of heat from impacts with planetesimals early in Earth's history. Impacts with large bodies such as these (including the impact which led to the formation of the moon) trapped the thermal energy of the collision in the surrounding rock of the planet, and may have been enough in certain circumstances to completely melt the early Earth.The second source of heat is also a remnant of an early Earth event known as the Iron Catastrophe. With much of early Earth still molten, denser metals, particularly iron and nickel, migrated to the center of the planet. Tremendous amounts of frictional heat was created, enough to completely melt the planet once again.The third source of heat in the Earth is from compression due to gravity.The fourth and final source of heat in the Earth is from the decay of radioactive elements. This source of heat is gradually declining due the decreasing amounts of radioactive isotopes, the decrease being caused by the decay.
What causes heat below the Earth's surface?
Aside from the sun, the heat present in the Earth is due to several factors. The first source of heat is from the remnants of heat from impacts with planetesimals early in Earth's history.

The fourth and final source of heat in the Earth is from the decay of radioactive elements.

What is produced by heat within earth?
Heat within the Earth produces geothermal energy, which can be harnessed for various purposes such as generating electricity, heating buildings, and greenhouse agriculture. This heat is generated from the decay of radioactive elements, residual heat from Earth's formation, and the heat from the Earth's core.

What makes the earths core so hot?
Heavy radioactive elements sunk to the center of the earth when it was molten because they were the most dense. Things like Uranium are responsible for the ongoing heat of the earth's core.
