Across
- 5. a storm system rotating around an area of low pressure which produces strong winds and heavy rain
- 6. the area where the ocean touches land
- 7. occurs when particles, or sediment, are left behind in a new place
- 11. land that rises above the land around it leaving a peak
- 12. a deep valley with very steep sides; running water wears away rock leaving deep groves byhind
- 14. occurs when wind, water or ice carry small pieces of dirt or rock, or sediment, from one place to another
- 17. these are formed when water dissolves rock, usually limestone; and leaves behind an open area underground
- 19. a body of land that has water all around it
- 20. a flat area on Earth's surface; it is formed when the rock making up the land gradually is worn by wind and water
- 21. a series of enormous waves created by volcanic eruptions, submarine landslides and large asteroids
Down
- 1. usually triangular shaped deposits of sediment at the mouth of a river; as a river loses energy, it drops dirt and sediment to create these
- 2. breaks in the rock/ Earth where slabs can move
- 3. this has to happen before erosion because rocks have to be broken down before they can be carried away
- 4. a place on Earth's surface that is much higher than the land around it; often has a peak
- 8. vibration of Earth caused by a release of built up energy that has been stored along a fault
- 9. wedging water can freeze in cracks of rock and cause the rock to break; this is a form of weathering
- 10. a low area between higher lands such as mountains; they are created when water and ice cut through the land
- 13. the breaking down of rock on the surface of the Earth by wind water or ice
- 15. one cause of a tsunami
- 16. the natural structures or features on the Earth's surface
- 18. dune land shaped by blowing winds, usually made of sand
