Answer 2

The answer is 1 – C. This region of the earth is called the mantle. This region is composed of ‘plastic’ rock. The plasticity is due to the fact that the temperatures are high enough to make the rocks liquid but they remain solid because of the high pressure in the region. The convection currents of the mantle are responsible for dragging along the continental plates of the earth’s crust, hence the tectonic movements.
