Weathering, erosion, soil

3. a vertical sequence of soil layers
5. loose covering of weathered rock and decayed organic material overlying earth's bedrock
6. distinct layer within a soil profile
8. solution containing a substance that produces hydrogen ions [H+] in water
11. weathering process that breaks down rocks and minerals into smaller pieces but does not involve any change in their composition
13. soil soil that has been moved from its parent material by water, wind, gravity, or glacier
15. mechanical weathering process that occurs when water repeatedly freezes and thaws in the cracks of rocks, often resulting in rocks splitting
16. erosion in which water running down the side of a slope carves a small stream channel

1. occurs when eroded materials are dropped in another location
2. chemical or mechanical process that breaks down and changes rocks on or near Earth's surface
4. mechanical weathering process in which outer rock layers are stripped away, often resulting in dome-shaped formations
7. chemical reaction of oxygen with other substances
9. process by which rocks and minerals undergo changes to their composition due to chemical processes
10. erosion that occurs when a rill channel widens and deepens
12. soil that develops from parent material which is similar to local bedrock
14. removal and transport of weathered material from one location to another by agents such as water, wind, glaciers, and gravity
