How does the slow movement of hot and cold rock in the mantle, called mantle convection, cause the movement of tectonic plates?
As mantle rock moves under the crust, it pulls the tectonic plates above it along for the ride. This is the concept known as Slab Pull theory.

A sample of rock is extracted from the ground. Scientists know that the ground where the rock was extracted is experiencing compression forces.
What would you expect to happen to the rock sample as it sits on the scientist's desk?
The rock sample will expand, because it is no longer being compressed by the rock around it.

How does the density of the rock at point A compare to the density of the rock at point C?
The rock at point A is less dense than at point C.
