What is the relationship between the mantle and the crust of Earth?
A) The crust sits motionless on top of the mantle and does not interact with it.
B) Convection in the mantle moves the continents around, but there is no transfer of material from the mantle to the crust or vice versa.
C) New layers of crust are formed when magma from the mantle flows out over old crust, and this old crust remains as the lowest level of the crust.
D) New crust is formed by magma rising from the mantle in some places, and old crust is pushed back down into the mantle in other places.

The mantle's convection currents drive the movement of tectonic plates, leading to the formation of new crust as magma rises and solidifies at mid-ocean ridges, and the subduction of old crust back into the mantle at convergent boundaries.
