Across
- 3. boundary where 2 plates pull apart
- 5. rock that is formed when a rock is exposed to intense pressure and heat without melting
- 7. forms when an oceanic plate collides with another plate
- 9. this happens to rock and turns into magma or lava
- 12. forms when two continental plates collide
- 13. moves rocks and sediment
- 14. pieces of rock created that have been broken down
- 16. rock formed when magma and lava cools and hardens
- 17. Earth layer made of solid iron and nickel
- 19. boundary where 2 plates move past each other
- 20. occurs when plants are lost due to climate change and cutting down trees leading to increased temperatures and little to no rainfall
- 21. Earth layer made of liquid iron and nickel
Down
- 1. middle layer of Earth between the crust and the core
- 2. creates sediment
- 4. occurs when large numbers of trees are removed from one area at the same time
- 6. type of rock formed when sediment is compacted and cemented
- 8. occurs when the population of an area increases drastically
- 10. surface layer of Earth that is made of the crust and upper mantle and is divided into pieces
- 11. event that can happen at any boundary but are most common at transform boundaries
- 15. drops sediment in a new location
- 18. boundary where 2 plates collide
