Across
  1. 1. type of rock formed from the compaction of sediment
  2. 5. type of physical weathering where pressure changes cause a rock to break into sheets
  3. 7. movement of sediment
  4. 8. type of physical weathering where a rock cracks due to heating up and cooling down
  5. 10. fossil fuel formed from plants like ferns
  6. 11. will break rocks physically without changing the rocks chemistry
  7. 12. sulfur and nitrogen mix with water in the atmosphere and rain down
  8. 13. chemical weathering where oxygen reacts with iron forming rust
  9. 15. physical weathering where a substance gets into a crack in a rock and breaks it apart
  10. 16. type of rock formed through heat and pressure
  11. 17. type of chemical weathering where a rock absorbs water and becomes soft
Down
  1. 2. when sediment is dropped into a new location
  2. 3. type of chemical weathering where carbonic acid and groundwater react to form caves
  3. 4. break a rock by changing its chemistry
  4. 6. type of physical weathering where rocks or tiny particles hit against other rocks causing them to smooth
  5. 9. breaking of rock into sediment
  6. 14. type of rock most resistant to weathering
