Across
  1. 1. a type of mass movement where a slope is undercut by erosion (e.g.: base of cliff eroded by waves)
  2. 4. forms when carbon dioxide combines with water (bubbles in soda)
  3. 6. caused by the tilt of Earth's axis and Earth's revolution
  4. 7. erosion where wind blows across loose sediment, leaving behind big particles

  11. 22. erosion the forms U-shaped valleys
  12. 23. the changes in the way the moon appears from Earth
  13. 25. causes night and day
  14. 26. can result after a massive star produces a supernova

  11. 20. causes rocks to weather to a reddish color
  12. 24. erosion that produces smooth, polished surfaces
  13. 25. water that flows over Earth's surface
  14. 27. movement of rock or sediment because of gravity, water, and wind
