The correct statement about the movement of plates that sit on top of the mantle is: They regularly move because of the convection currents of magma.
The correct statement about the movement of plates that sit on top of the mantle is that they regularly move because of the convection currents of magma.
To arrive at this answer, we can eliminate the first two options as they are identical and not accurate. The plates do indeed move, so these options are incorrect.
The last option states that the movement of the plates is due to the convection currents of magma, which is the correct explanation. The movement of the plates is a result of the convection currents in the Earth's mantle. As the hot magma rises and cools, it spreads out and pushes the plates apart. Similarly, as the cool magma sinks, it pulls the plates together. This continuous movement of the plates is responsible for various geological phenomena, such as earthquakes, volcanic activity, and the formation of mountains.
