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