Across
- 7. pieces of rock collide with each other due to transportation by the wind, ice, water and gravity
- 8. are formed when water dissolves minerals and deposits them elsewhere
- 9. occurs when oxygen from the air combines with iron-rich minerals of the rock
- 11. layers of rock peel off the main body of the rock
- 13. material that ends up being transported by mediums and left in different landmasses
- 14. the wearing away of soil or rock by water, wind or ice
- 15. the physical and chemical breakdown of rocks at or near the surface
- 16. the collisions cause the particles to change size and shape
- 17. the mechanical or physical breakdown of rock into smaller pieces, without a change in the mineral's chemical composition
- 19. occurs when water combines with carbon dioxide in the air to form carbonic acid
- 20. the process of removing empty spaces between minerals by the weight of overlying sediment
Down
- 1. soil is formed from the parent material and is of the same composition
- 2. are produced by mechanical weathering and are classified by grain size, sorting, and angularity
- 3. parent material has been carried from elsewhere and deposited
- 4. the process of "gluing" the compacted minerals together by minerals that filter through the sediment
- 5. the process by which chemicals break down rock through a change in the mineral's composition, happens fastest in a hot, moist climate
- 6. are formed by the action of organisms as they build shells and other body parts by extracting chemical companies from the water in which they live
- 10. the tendency for currents of air or water to separate sediments according to size
- 12. water freezes in a crack of the rock surface, expanding and splitting the rock
- 18. water combines with minerals such as mica and feldspar found in granite, to form clay, the rock weakens and crumbles apart
