Crust
Mantle
Outer Core
Inner Core
2. Which layer is the thinnest and makes up the Earth's surface?
Crust
Mantle
Outer Core
Inner Core
3. The Earth's outermost layer, the , is rigid and brittle.
4. Convection currents within the are responsible for plate tectonics.
5. The extreme pressure in the keeps it solid despite its high temperature.
6. The Earth's magnetic field is generated by the solid inner core.
True
False
7. Oceanic crust is generally thicker and less dense than continental crust.
True
False
8. Describe the primary differences in composition and state of matter between the outer core and the inner core.
9. Explain the role of the mantle in the movement of tectonic plates.
