Down
- 1. Thicker and less dense type of crust found under the continents
- 2. Currents in the mantle that drive the movement of tectonic plates
- 3. Weak, plastic layer of the upper mantle beneath the lithosphere
- 4. Waves that travel through the Earth's layers during an earthquake
- 6. Lower layer of the mantle, between the asthenosphere and outer core
- 9. Layer between the crust and core, made of hot, dense rock
- 10. Shaking of the Earth's surface caused by movement along a fault
- 12. Plates that make up the Earth's lithosphere and move slowly over time
