Quiz 7: Unit 4. Part 2. Question 8. Watch the Unit 4 Part 2 lecture video and answer the following question: Why is the asthenosphere the weakest region in the mantle? a. Because it is the closest to its melting temperature b. Because it is at the top of the mantle where pressures are least c. Because it is at the bottom of the mantle where temperatures are greatest d. Because it is the lithosphere is on top it
Because it is the closest to its melting temperature

Quiz 7: Unit 4. Part 2. Question 9. Watch the Unit 4 Part 2 lecture video and answer the following question: The Earth's mantle below the lithosphere is a solid (it has a crystalline structure), but it is also close to its melting temperature, so it flows like a fluid. How does heat transfer through the mantle? a. Conduction b. Convection c. Radiative Heat Transfer
Convection
