What is a destructive force caused by the convention in the mantle?

A destructive force caused by convection in the mantle is plate tectonics, which can lead to earthquakes and volcanic eruptions. As the mantle's convection currents move, they can cause tectonic plates to shift, collide, or pull apart. This movement generates stress along fault lines, resulting in seismic activity, while subduction zones can create volcanic activity as one plate descends beneath another. Both phenomena can cause significant destruction to the environment and human structures.
