Across
- 7. magma that reaches the surface
- 8. cutting down trees, lack of roots leads to erosion, increase in carbon dioxide levels
- 9. breaking down of sediments over time
- 11. small particle size, hard for water to go through
- 12. cannot renew in a timely manner
- 13. if water temperatures are ---- water becomes more dense
- 14. excess pollution, decreases ground water, soil erosion from clearing trees
Down
- 1. replenish and can be reused in a short amount of time
- 2. plates slip past each other causing a earthquake
- 3. best soil for growing plants
- 4. surface water seeps into the soil
- 5. plates pull apart and magma rises in between to make new crust
- 6. movement of weathered materials
- 10. molten rock underground
