slab-pull
The main source of downward convection flow in the mantle is called "slab pull." This process occurs when a denser oceanic plate sinks into the mantle at a subduction zone, pulling the rest of the plate behind it. This movement helps drive the overall convective flow in the mantle.
The difference in temperature and density is the cause of convection currents in the earths mantle. Convection currents are the flow that transfers heat within a fluid.

The heat source for the convection currents in the mantle is primarily the heat leftover from Earth's formation and the heat produced by radioactive decay of elements within the mantle. The heat from the Sun does not directly drive mantle convection, although it does play a role in surface processes like weather and climate.
Bad grammar.
False.
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.

No. It's radioactive decay within the planet.
