Question 1 of 8 • CMS Summer 2026 Earth and Environmental Science CREDIT RECOVERY

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.
