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