Across
- 5. vents in earth's crust through which molten rock flows
- 8. The process that occurs when one tectonic plate moves under another tectonic plate
- 9. The material formed from rocks broken down by weathering
- 11. The mechanical and chemical process that changes earth's surface over time
- 12. the partial melted portion of the mantle below the lithosphere
- 14. The downhill movement of a large mass of rocks or soil due to gravity
- 15. A boundary where two plates move away from each other
- 17. The process of breaking down rocks without changing the composition of the rock
- 20. Large masses of ice, formed by snow accumulation on land, that move slowly across Earth's surface
- 21. Two plates that slide past each other
- 22. tectonics Earth's surface is broken into large rigid pieces that move with respect to each other
Down
- 1. The circulation of fluids caused by differences in density and thermal energy
- 2. Long narrow mountains formed by magma
- 3. A boundary where two plates move towards each other]
- 4. The vibrations caused by the rupture and sudden movement of rocks along a break or crack in earth's crust
- 6. The crust and uppermost part of the mantle
- 7. The process that changes the composition of rocks
- 10. The moving of weathered material or sediment
- 13. A crack or a fracture in earth's crust along which movement occurs
- 16. molten rock stored beneath earth's surface
- 18. Magma that erupts onto Earth's surface
