Key concepts
3 concepts
- 1
The two types of Earth's crust are continental and oceanic, with oceanic crust being more dense.
- 2
The Earth's mantle is a solid, but malleable layer that convects like a lava lamp, transferring heat to the surface.
- 3
The Earth's magnetic field is generated by the geodynamo effect in the liquid outer core, and the solid inner core helps stabilize this field.
Part 3 of 4
Practice
3 questions
Describe the process of mantle convection and its role in transferring heat from Earth's interior to its surface.
Explain how the D’’ layer contributes to heat transfer within Earth and discuss one hypothesis about its composition or function.

Quick comprehension check
“Describe how heat is transferred from Earth's core to the mantle, and explain the effect of this heat transfer on the mantle's properties.”
