Question 1 of 3 • (OC27) Earth/Space Sci-2001310-S1-Nelson

Which statement explains how convection currents affect the movement of plates?

Answer

A

Gravity pulls one edge of a plate down into the mantle, which causes the rest of the plate to move as well.

B

Heat from Earth’s interior causes lithospheric plates to collide at convergent plate boundaries, causing volcanoes.

C

Heat from Earth’s interior causes currents of hot rising magma and cooler sinking magma to flow, moving the crust along with them.

D

As convection currents drift across the oceans, they bring the pieces of Earth’s crust with them as the supercontinent breaks apart.
