The earth’s mantle is made of a dense thick material that causes movement of crustal plates. Crustal plate movement occurs because the mantle flows as a result of uneven heating inside the mantle. Very hot material deep in the mantle creates _____________ that rise, then cool, then sink, and then heat again, with the cycle repeating.

Question

Responses
A magma flowsmagma flows
B magma currentsmagma currents
C magnetic wavesmagnetic waves
D convection currents

Answer 1

The correct response is:

D convection currents

Convection currents in the mantle are responsible for the movement of crustal plates due to the cycle of heating, rising, cooling, and sinking of the material.
