Across
- 2. / lat-topped, steep-sided towers of rock smaller than plateaus and mesas.
- 5. / the laying down or settling of eroded material.
- 9. Weathering / the process that changes the composition of rocks and minerals to exposure to the environment.
- 10. Stress / thermal stress is created by changes in the temperature of a rock causing it to expand and contract. These stresses can lead to breaking of rocks.
- 11. / a depression, or dip, in the Earth's surface.
- 12. / a naturally raised area of land, not as high or craggy as a mountain.
- 13. / a large mass of ice, formed by snow accumulation on land, that moves slowly across Earth's surface.
- 17. / the grinding away of rock or other surfaces as particles carried by wind, water or ice scrape against them.
- 18. / the process that combines the element oxygen with other elements or molecules.
Down
- 1. / a large deposit of sediment that forms where a stream enters a large body of water.
- 3. / weathered material that settles to the bottom of a river, lake, or ocean.
- 4. / a large natural elevation of the earth's surface rising abruptly from the surrounding level; a large steep hill.
- 6. / the mechanical and chemical processes that change Earth's surface over time.
- 7. Weathering / physical processes that naturally breaks rocks into smaller pieces.
- 8. Wedging / Ice wedging is a form of physical weathering in which cracks in rock or other surfaces fill with water, freeze and expand, causing the cracks to enlarge and eventually break.
- 14. / the moving of weathered material, or sediment, from one location to another.
- 15. / an area of relatively level high ground.
- 16. / a natural feature of the earth's surface like mountains, hills, plateaus, buttes, and basins.
