the mantle plume There are two source of heat in the earth's interior. The main two sources are fire and breathing heat.
The main source of the Earth's external heat is the Sun. Solar radiation is absorbed by the Earth's surface, leading to an increase in temperature and driving various processes on our planet. Additionally, heat from the Earth's interior, generated by radioactive decay and leftover heat from the planet's formation, also contributes to the overall heat budget.
What needs a heat source to begin evaporating. Normally the sun is the heat source that evaporates water on the earths surface.
Any external heat source can provide the required energy.
Yes they are - the need an external heat source to raise their temperature.
The sun as it is the most powerful heat source in our solar system.
