Across
- 2. The Mechanical or physical breakdown of rock into Smaller pieces sediments), without a change in the minerals composition.
- 3. The process by which chemicals break down rock through a change in the minerals composition.
- 4. The physical and chemical breakdown of the rocks at or near surface
- 9. Chemical Sedimentary rocks are formed when water dissolves minerals and deposits them elsewhere.
- 10. Occurs when water combines with carbon dioxide in the air to form carbonic acid
- 12. Biochemical sedimentary rocks 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 (think Limestone)
- 13. The tendency for currents of air or water to separate sediments.
- 14. The wearing away of soil or rock by water, wind, or ice.
- 15. The process of gluing the compacted materials together by minerals that filter down through the sediment.
- 16. The process of removing empty spaces between minerals by the weight of the over-lining sediment.
- 17. Occurs when oxygen from the air combines with iron-rich minerals of the rock.
- 18. The material that will end up being transported by water wind gravity and ice.
Down
- 1. water combines with minerals such as mica and feldspar found in granite,to form clay, the rock weakens andcrumbles apart.
- 5. Parent material has been carried from elsewhere and deposited.
- 6. 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.
- 7. Pieces of rock collide with each other due to transportation by wind, ice, water, and gravity.
- 8. soil is formed from the parent material and is of the same composition.
- 9. Clastic rocks are produced by Mechanical weathering and are classified by grain size, sorting and angularity.
- 11. The water freezes in a crack of the rock surface expanding and splitting the rock.
- 14. Layers of rock peel off the main body of the rock.
