Across
- 3. Process that breaks down rocks and minerals into smaller pieces but does not involve any change in their composition
- 6. Chemical weathering process where acid reacts with limestone and breaks it down
- 7. Transport of weathered materials from one location to another by agents such as water, wind, glaciers, and gravity
- 9. Physical weathering process that occurs when water repeatedly freezes and thaws in cracks in rock, eventually splitting the rock apart
- 10. Process by which rocks and minerals undergo changes in their composition due to chemical reactions with agents such as acids, water, oxygen, and carbon dioxide
Down
- 1. Occurs when eroded materials are dropped off in another location and settle there
- 2. Physical weathering process where the outer layers of a rock peel or flake off due to extreme fluctuations in temperature
- 4. Physical weathering process where rocks get grinded down by sediments or other rocks, often carried by water or wind
- 5. Physical weathering where roots grow into cracks in rocks, then expand, breaking the rock apart
- 8. Chemical reaction between oxygen and other substances - in rocks it occurs mainly with iron
