Across
- 2. Occurs when oxygen from the air combines with iron rich minerals of the rocks. (= Rust)
- 5. The lithification of organic material into things like coal.
- 8. When a rock is transported by wind, water, or ice, and put elsewhere.
- 9. The physical and chemical breakdown of rocks at or near the surface.
- 11. The mechanical or physical breakdown of rock into smaller pieces.
- 12. Parent material has been carried from elsewhere and deposited.
- 13. The process of removing empty spaces between minerals by the weight of the overlying sediment.
- 15. Water freezes in a crack of the rock surface, expanding and splitting the rock.
- 16. Formed by the action of organisms as they build shells and other body parts by extracting chemical components.
- 17. Layers of rock peel off the main body of the rock.
- 19. When water combines with minerals such as mica and feldspar found in granite, to form clay, the rock weakens and crumbles apart.
Down
- 1. As sediment is transported from its source to where it is deposited, the particles collide with each other and with other objects in their path.
- 3. The tendency for currents of air or water to separate sediments according to size.
- 4. Soil formed from the parent material and is of the same composition.
- 6. Pieces of rock collide with each other due to transportation by wind, ice, water, and gravity.
- 7. The process of “gluing” the compacted minerals together by minerals that filter through the sediment.
- 10. The process by which chemicals break down rock through a change in the mineral’s composition.
- 11. Occurs when water combines with carbon dioxide in the air to form carbonic acid.
- 14. When water dissolved minerals and deposits them elsewhere.
- 18. The wearing away of soil or rock by water, wind, or ice.
