Back

Convection.

What is the role of the mantle in Earth's structure?

Back

The mantle is a thick layer of rock between the Earth's crust and core, involved in convection currents.

Front

What is the effect of temperature on the density of materials in the mantle?

Back

As temperature increases, materials become less dense and rise; as they cool, they become denser and sink.

What is conduction?

Back

Conduction is the transfer of heat through a solid material without the movement of the material itself.
