Across
- 2. breaking down rocks by factors such as pressure, temperature, water, and ice
- 4. when sediments are deposited (dropped off) in a different location
- 7. wearing down of rock particles by friction due to water or wind or ice
- 9. weathering caused by water going into a crack in a rock; the water freezes and makes the crack even bigger when it expands and turns to ice
- 10. process when oxygen combines with an element, changing the element
Down
- 1. weathering caused by plants growing in the cracks of a rock - roots spread the crack until the rock breaks
- 3. water droplets that are acidic due to the polluted atmosphere
- 5. breaking down rocks though some sort of chemical reaction
- 6. moving of smaller pieces of broken rock by natural forces, such as wind, water, or ice
- 8. an underground layer where the ground contains water
