  1. 4. Refers to the shape of sediment particles, specifically how rounded or angular they are, which can provide clues about the distance and intensity of their transportation.
  2. 7. (as type of sedimentary rock): Sedimentary rock formed from the precipitation of minerals dissolved in water, often through processes like evaporation or chemical reactions.
  3. 9. action: The mechanical weathering process where water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart.
  4. 13. A chemical reaction where a substance combines with oxygen, often leading to changes in the substance's properties or appearance.
  5. 14. The chemical reaction of minerals with water, resulting in the breakdown of minerals and the formation of new substances.
  6. 15. The chemical reaction of carbonate minerals with water containing carbon dioxide, resulting in the dissolution of minerals like limestone.
  7. 17. Weathering: The breakdown of rocks into smaller pieces without altering their chemical composition, often caused by physical forces like temperature changes, ice formation, or pressure.
  8. 18. The mechanical wearing away of rock surfaces by friction or impact during transportation by natural agents like water, wind, or ice.
  9. 19. Weathering: The breakdown or alteration of rocks through chemical processes like dissolution, oxidation, or hydrolysis, changing the composition of the rocks.
  10. 20. dome: A landform resulting from the weathering process, where curved layers of rock peel or flake off due to pressure release, often forming dome-like structures.

  1. 1. The separation of sediment particles by size, typically occurring during transportation by agents like water or wind, resulting in layers of sediments with similar particle sizes.
  2. 2. The process in which sediments are squeezed and compacted by the weight of overlying materials, reducing pore space and solidifying sediment into rock.
  3. 3. soil: Soil formed by the weathering of underlying bedrock in place, without being transported away.
  4. 5. The process by which rocks and minerals are broken down or altered at or near the Earth's surface due to various physical, chemical, or biological processes.
  5. 6. The process in which minerals precipitate in the pore spaces between sediment grains, binding them together to form a solid rock.
  6. 8. soil: Soil that has been moved from its original location by natural agents like water, wind, or glaciers and deposited elsewhere.
  7. 10. The movement of weathered materials (such as rocks, soil, and sediment) by natural agents like water, wind, ice, or gravity.
  8. 11. (as type of sedimentary rock): Sedimentary rock composed of fragments of pre-existing rocks or minerals, called clasts, which are cemented together.
  9. 12. sedimentary (as type of sedimentary rock): Sedimentary rock formed from the accumulation and lithification of organic materials, such as shells or plant debris.
  10. 16. The process by which eroded materials are laid down or deposited in a new location by natural agents like water, wind, ice, or gravity.
