Which statement is correct about movement of plates that sit on top of the mantle?

Question

1.They never move because they are connected to Earth's crust.
2.They regularly move because of the convection currents of oceans.
3.They never move because they are connected to mountains.
4.They regularly move because of the convection currents of magma.

Answer 1

The correct statement about the movement of plates that sit on top of the mantle is:

4. They regularly move because of the convection currents of magma.

Tectonic plates are situated on the semi-fluid asthenosphere of the mantle, and their movement is driven by convection currents caused by the heat from the Earth’s interior, which results in the movement of magma.
