Across
- 2. heat transfer by the movement of currents in a liquid
- 3. the theory that states that pieces of the Earth's lithosphere are in slow, constant motion driven by convection currents in the mantle
- 5. Liquids rise and fall in a convection current because of this
- 9. a single section of the lithosphere
- 12. A soft sublayer of the mantle
- 14. the place where two plates collide
- 15. core The solid sublayer of the core

Down
- 1. the place where two plates move away from each other
- 2. The innermost layer of the Earth
- 4. The uppermost layer of the mantle and the crust
