Convection Currents in the Mantle

Front

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

Back

They rise up.

Front

What causes convection currents in the mantle?

Back

Differences in temperature and density.

Front

What is the primary heat source for convection in the mantle?

Back

The Core.

Front

At which layer does heated material begin to cool down and become more dense?

Back

The Crust.

Front

Define convection currents.

Back

Convection currents are the movement of fluid caused by differences in temperature and density.

What role does the Core play in mantle convection?

Back

The Core provides the heat that drives convection currents in the mantle.

Front

Explain why less dense materials rise in the mantle.

Back

Less dense materials rise because they are lighter than the surrounding denser materials.

Front

What is the relationship between temperature and density in the mantle?

Back

As temperature increases, density generally decreases, causing materials to rise.
