Across
- 5. a process that displaces rock layers when surfaces on either side of a crack in the Earth's surface shift
- 6. any changes to the Earth's crust that result from two tectonic plates converging
- 11. circular movement of molten magma in the mantle that causes tectonic plates to shift
- 14. plate boundary where two plates collide into each other
- 16. processes that help build, shape, or initiate geologic features like mountains and volcanoes
- 17. the area extending from a stream to its valley walls; where sediment is deposited when the stream overflows
- 19. type of geologic activity that is measured on the Richter Scale
- 20. extremely small particles of sand, rock, or dirt that are removed from the Earth's surface and deposited elsewhere
- 21. the slow, broad, upward movement of the Earth's surface
Down
- 1. is the feature that forms when sediment from a stream or river flows into a larger body of water
- 2. slope of a river or stream
- 3. type of rock known for its small crystals and striations(layers)
- 4. the feature that forms where a stream or river ends and deposits sediment on land
- 7. the process that occurs when two plates converge, causing the crust to fold over onto itself
- 8. type of rock characterized by its large air pockets and crystals; formed by lava cooling
- 9. processes that break down or wash away the surfaces of geologic features
- 10. to get pulled under the other tectonic plate at a convergent plate boundary
- 12. a landform that results when increased pressure is put on rock layers causing them to fold downward
- 13. a landform that results when increased pressure is put on rock layers, causing them to fold upward
- 15. transportation of sediment through mediums like water and air
- 18. type of rock known for containing fossils
