Question

1. which of these is responsible for moving the giant plates that make up earths crust and cause the continents to drift?

a) ocean waves
b) convection in the mantle (hot, moving rock beneath the crust)
c) tornadoes
d) wind

Explanation:

The movement of Earth's tectonic plates and continental drift are caused by convection currents in the mantle. Hot, semi - molten rock (magma) in the mantle rises, cools, and then sinks, creating a cycle of movement that exerts force on the plates above. Ocean waves, tornadoes, and wind do not have the power to move tectonic plates.

Answer:

B. Convection in the mantle (hot, moving rock beneath the crust)
