What was not a source of heat for early earth?
bombardmant by meteorites and asteroids.
What is the source of earths internal heat?
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 is Geothermal source?
A geothermal source is, quite literally, a source of heat from the earth. (Geo means the earth, and thermal means heat.)
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 a source of external heat energy for the earth?
the sun? Yes, I am pretty sure the Sun is a major source of heat for the Earth
Was not a source of heat for early Earth?
hydrothermal energy
What was not a source of heat for early earth?
bombardmant by meteorites and asteroids.
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 produced by heat within earth?

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. 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 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 caused by the decay.
