The correct statement about the movement of plates that sit on top of the mantle is that they move due to the convection currents in the underlying mantle.
The correct statement about the movement of plates that sit on top of the mantle is that they move due to the process of plate tectonics. This theory explains how the Earth's lithosphere, which is composed of several large and small plates, moves and interacts with each other. The movement occurs because the lithosphere, which includes the crust and uppermost part of the mantle, is broken into several pieces known as tectonic plates. These plates move slowly over time, driven by convection currents in the underlying semi-fluid asthenosphere of the mantle. The movement of these plates can cause various geological phenomena, such as earthquakes, volcanic activity, and the formation of mountains and oceanic trenches.
