Earth Convection Currents

Convection currents in the Earth's mantle are caused by:

• Less dense hot magma moving downward

• Less dense hot magma moving upward

• Tectonic plate movement

• More dense cooler magma moving upward

Convection currents occur when ______________________ energy transfers between a fluid.

• potential

• kinetic

• thermal/heat

• electric
