3. Measure of void spaces in a material
5. The freezing and de thawing of water
6. The mechanical breakdown of rocks into smaller pieces that is caused by natural processes and that does not change the chemical composition of the rock material
8. The flow of a mass of mud or rock and soil mixed with a large amount of water
9. The rock material carried and deposited by glaciers
12. Large glaciers that grow in valleys
13. Rain, sleet, or snow that contain high amounts of acid
15. WEATHERING The chemical breakdown and decomposition of rocks by natural processes in the environment
17. The process in which material is laid down
19. The process by which wind, water, ice, of gravity transporte soil and sediment from one location to another
20. The natural process by which atmospheric and environmental agents, such as wind, rain, and temperature changes, disintegrate and decompose rocks

1. Continuous glaciers that are much larger than alpine glaciers
2. An area along a river that forms from sediments deposited when the river overflows it’s banks
4. A chemical reaction in which a material combined with oxygen to form new material; this is a chemical reaction
7. A large mass of ice that exists year - round and moved over land
10. A mound of wind deposited sand that moves as a result of the action of wind
11. Mass rocks and sediments carried down a glacier
13. The process by which rock is reduced in size by the scraping action of other rocks driven by water, wind, and gravity.
14. A fan-shaped mass of material deposited by a stream when the slope of the land decreases sharply
16. The sudden movement of rock and solid down a slope
17. A mass of material deposited in a triangular or fan shape at the mouth of a river or stream
18. The slow downhill movement of weathered rock material
