Across
- 1. of fragments of pre-existing rock that have been transported some distance from their points of origin
- 2. Oxidation,A biochemical reaction involving the transfer of a negatively charged electron from one organic compound to another organic compound or to oxygen
- 6. soil,landform that was produced as the remains of an ancient landscape, escaping burial or destruction to remain as part of the present landscape
- 8. dome,a process in which large flat or curved sheets of rock fracture and are detached from the outcrop due to pressure release
- 9. Weathering,a process that causes the disintegration of rocks, mineral, and soils without chemical change
- 11. the laying down of sediment carried by wind, flowing water, the sea or ice
- 14. soil,soils have been transported in from somewhere else.
- 15. the precipitation of a binding material around grains, thereby filling the pores of a sediment
- 16. grouping objects or events according to their similarities
- 17. interaction of rock with mineral solutions (chemicals) to change the composition of rocks.
Down
- 1. the decrease in the volume of a fixed mass of sediment
- 3. physical process of rubbing, scouring, or scraping whereby particles of rock (usually microscopic) are eroded away by friction.
- 4. breakdown of rock by acidic water to produce clay and soluble salts.
- 5. Weathering, the interaction of rock with mineral solutions (chemicals) to change the composition of rocks.
- 7. the process of wearing or being worn by long exposure to the atmosphere.
- 8. the process of eroding or being eroded by wind, water, or other natural agents.
- 10. the mixing of water with carbon dioxide to make carbonic acid.
- 12. action,the process of alternate freezing and thawing of moisture in soil, rock and other materials, and the resulting effects on materials and on structures placed on, or in, the ground.
- 13. a surface between overlying, young, flat rocks and underlying, older, tilted rocks.
