Convection in the Earth's Mantle

Convection in the Earth's Mantle

Read each question carefully and answer to the best of your ability. Refer to the diagram of Earth's layers when needed.

Observe the diagram of Earth's layers below:

1. What is the primary method of heat transfer within the Earth's mantle?

2. Which layer of the Earth is responsible for generating convection currents?

3. Convection occurs when hotter, less dense material  , and cooler, denser material  .

4. The movement of tectonic plates is driven by   in the mantle.

5. The Earth's mantle is a completely liquid layer.

6. Convection currents in the mantle are responsible for volcanic activity and earthquakes.

7. Briefly explain how convection currents in the mantle contribute to the movement of tectonic plates.
