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