Where does convection occur in the Earth?

• Crust

• Core

• Mesosphere

• Mantle

What is convection?

• The circular motion that happens when cooler air or liquid — which has slower moving molecules, making it more dense

• The circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense

• The circular motion that happens when extremely hot air or liquid — which has faster moving molecules, making it very, very dense.

• None of the above
