Convection Currents in the Mantle

Front

What happens to molecules that are less dense than the surrounding particles?

Back

They are pushed up by more dense particles.

Front

What occurs to molten material when it is heated in the mantle?

Back

What is density?

Back

Density is the mass of a substance divided by its volume.

Front

Explain how heating affects the density of materials in the mantle.

Back

Heating causes materials to expand, making them less dense.
