Earth's Layers and Convection Currents Quiz

What are convection currents?

• The movement of fluids due to differences in pressure and volume.

• Movement of fluids due to differences in temperature and density.

• The movement of solids due to differences in temperature and density.

• The movement of gases due to differences in color and texture.
