Unit 7-Weathering/Erosion/Deposition and Landforms

3. Process that breaks down rocks through chemical changes
4. Process that occurs when the agents of erosion deposit, or lay down, sediment
5. The grinding away of rock by other rock particles carried in water, ice, or wind
6. Process that moves weathered material (sediment) from one place to another
10. A mound of sand built up by wind
13. Process in which a chemical substance changes because of the addition of oxygen
14. A triangular or fan shaped landform made of sediment that is deposited where a river flows into an ocean or lake
16. Breaking down rocks and minerals into smaller pieces without changing their chemical composition
17. A large mass of ice that moves slowly over land

1. A natural feature of the solid surface of the Earth
2. Any form of precipitation with acidic components
7. A large stream of water that flows across land along a channel
8. A region of increased elevation on Earth’s surface that rises to a peak
9. Water gets into cracks of rocks, freezes, and expands, breaking the rock
11. Basin of fresh or salt water surrounded by land
12. The boundary between land and ocean (or a lake)
15. Rock, minerals, and organic matter that has been broken down into small pieces by weathering Breakdown of rocks and mineral matter through physical or chemical processes
