  2. 5. A low-lying wet grassy land of vegetation
  3. 6. where deposition takes place
  4. 9. the dropping of sediments
  5. 10. A type of weathering where the composition is not changed
  6. 11. soil particles moving slowly downhill
  7. 12. When acid rain reacts with rock--forming minerals such as feldspar to produce clay.
  8. 13. a chemical change in which a substance combines with oxygen, as when iron oxidizes, forming rust - Chemical Weathering
  9. 14. sediment that was deposited by a glacier
  10. 15. Where erosion takes place
Down
  1. 1. When CO2 dissolves in rain water and creates carbonic acid and weathers limestone to form caves and sink holes - Chemical Weathering
  2. 3. when wind erosion piles up sand(deposition)
  3. 4. rain, sleet, or snow that contains a high concentration of acids - Chemical Weathering
  4. 7. the moving of sediments from one place to another
