Across
- 5. layer of mostly granite
- 6. shear wave that can't move through liquid
- 7. this guy came up with continental drift theory
- 9. solid and really dense
- 11. layer of mostly basalt
- 12. hot, partially melted slowly flowing layer of upper mantle
Down
- 1. like the asthenosphere but more dense and flows way slower
- 2. cool rigid outer layer
- 3. compression wave that can move through liquid
- 4. this boundary has deeper earthquakes where movement is deep in earth and thick layer of sediment and old crust
- 8. this boundary has shallow earthquakes happen here and thin layer of sediment and young crust
- 10. dense, viscous liquid
