Question

understanding convection currents
which statement accurately describes the movement of earths plates due to convection currents?
material near the core cools as heat is transferred toward the crust.
heated materials become denser, causing them to rise toward the surface.
as heated material gets closer to the surface, it begins to cool.
as materials cool, they become less dense and sink back toward the core.

Explanation:

In convection currents in Earth's mantle, heated material rises, and as it gets closer to the surface, it cools. Material near the core heats up, not cools as heat is transferred outward. Heated materials become less - dense and rise. Cooled materials become denser and sink.

Answer:

As heated material gets closer to the surface, it begins to cool.
