Continental Drift & Plate Tectonics
Across
- 2. Earth's crust is broken up into pieces called _________.
- 4. preserved remains or traces of organisms that lived in the past
- 6. appears to be a large crack along the land with a river running through it
- 7. large flat area of land
- 10. Plate boundary that is created when two plates slide past each other
- 14. high points of land with a flat top
- 15. This theory believes that the continents only move because they are on top of the plates that are actually moving
- 16. caused by divergent plate boundary when they separate from each other on land
- 17. drift a) the continents used to be together/connnected (Pangea)b) the continents are moving and are still moving from old locations to new locations
- 19. caused by divergent plate boundary when they separate from each other in the ocean
Down
- 1. low point between two mountains
- 3. caused by a convergent plate boundary when they collide
- 5. made of compressed tropical plants
- 6. Plate boundary that is created when two plates collide
- 8. Plate boundary _____________ causes landforms and events to occur.
- 9. cracks where one plate touches another plate
- 11. Plate boundary that is created when two plates divide/separate
- 12. caused by transform plate boundary when they slide past each other
- 13. height of land above or below sea level
- 18. deep points below the ocean along the sea floor
