Water 21-22

1. Largest reservoir of liquid freshwater
5. Narrow area on top a chain of hills or mountains
7. Liquid to a gas.
9. Heat causes the rock to expand and fracture
13. Grinding away of rock by other rock particles carried in water, ice, or wind
15. Steep rock face; vertical or nearly vertical slope
18. Breaking down of rocks and other materials
20. Narrow and deep low area that forms between hills or mountains; usually has a stream/river flowing through it; deeper than a valley with steeper and more narrow sides
21. Water moving into or through the surface of a landform
24. Water's movement across surface landforms
25. Area of land extending well above the surrounding terrain; typically has steep sides
28. Sediment is laid down in new locations
31. Breakup of rock caused by the expansion of freezing water in cracks and crevices
32. Liquid to a solid
33. Reservoir that is in the gaseous state
34. Solid to a liquid
36. Area of a glacier where more mass is gained than lost.
37. The force responsible for the flow of water
38. Narrow and deep low area that forms between hills or mountains; usually has a stream/river flowing through it; formed by water
39. Place where a river empties into another body of water
41. Small, solid pieces of material that come from rocks or living things
42. Largest reservoir of freshwater

2. Anything that can hold water
3. Rock, sand, and soil are broken down and carried away
4. Ability for a liquid to pass through a substance
6. Gas to a liquid.
8. Largest reservoir
10. The point where a river begins
11. The bottom of a river
12. This occurs when water reaches the lowest point it can flow based on elevation
14. Flat and elevated landform with steep sides from a hill or mountain
16. Water in the atmosphere gets too heavy to stay suspended, it falls in the form rain, snow, hail, sleet, dew, or frost.
17. A ridge of till piled up along the front edge of a glacier.
19. The roots of a plant (typically a tree) wedge into a crack in a rock and, as the plant grows, splits the rock.
22. Amount of water vapor in the atmosphere
23. Natural connection of flowing water from one reservoir to another
26. Narrow and deep low area that forms between hills or mountains; usually has a stream/river flowing through it; formed by glacial cuts; flat at the bottom with steep, but smooth sides
27. Amount of open space an object has; could be between grains, cracks, or cavities in a layer of a substance
29. Large body of water surrounded by land; not as large as an ocean
30. Location on glacier where melting is faster than snow accumulation
35. The sides of a river
40. Area of land extending above the surrounding terrain
