The convection currents within a mantle are one of the reason plate movements of the earth. Explain how?

Yes.

Explanation:

Yes, the convection currents within a mantle are one of the reason plate movements of the earth because in the convection current, the heated mantle material is rising from deep inside the mantle, whereas cooler mantle material sinks. Convection current is the process in which the hotter mantle moves from deep to the upper side and the upper mantle sinks which leads to the movement of plate inside the earth that causes earthquake.
