Step 1Let's solve this step by step:
Step 2: Understand Mantle Convection
Mantle convection is a fundamental process in Earth's interior where heat drives the movement of material in the mantle. This process is similar to how heat causes movement in a pot of boiling water.
Final Answer
Cooler, denser material moves down, while warmer, less dense material moves up, creating a circular convection current in the mantle.
