Answer 1

The best answer is:

It is made possible by heat and pressure.

Convection currents are driven by the heat from the Earth's interior, which causes the movement of molten rock in the mantle. While convection currents play a role in geological processes, they do not happen in all layers of the Earth, and they do not directly cause earthquakes or the formation of valleys and hills in all cases.
