Weathering

1. / a low oval mound or small hill, typically one of a group, consisting of compacted boulder clay molded by past glacial action.
3. / a half-open steep-sided hollow at the head of a valley or on a mountainside, formed by glacial erosion.
5. / the fertile, upper part of the soil
7. / a small area in which demonstrators or protesters are confined by police seeking to maintain order during a demonstration.
10. / a layer generally parallel to the soil crust, whose physical characteristics differ from the layers above and beneath
12. / a winding curve or bend of a river or road.
16. / the process or result of oxidizing or being oxidized.
19. / a scraped spot or area; the result of rubbing
20. / an area of land where all precipitation that falls will drain or flow downhill into a specific stream.
21. / a covering of ice over a large area, especially on the polar region of a planet.
22. / is a type of rock weathering where the rock's layers peel off in whole sheets instead of grain by grain
24. / a long ridge of gravel and other sediment, typically having a winding course, deposited by meltwater from a retreating glacier or ice sheet.
26. / the various mechanical and chemical processes that cause exposed rock to decompose
28. / a river or stream flowing into a larger river or lake.
29. / an area or ridge of land that separates waters flowing to different rivers, basins, or seas
30. / split and shed

2. / a mass of rocks and sediment carried down and deposited by a glacier, typically as ridges at its edges or extremity.
4. / the state of being deposited or precipitated
6. / unsorted material deposited directly by glacial ice and showing no stratification
8. / the chemical breakdown of a compound due to reaction with water.
9. / A steep-sided, U-shaped valley formed by the erosional forces of a moving glacier.
11. / the process by which the surface of the earth is worn away by the action of water, glaciers, winds, waves, etc.
13. / rainfall made sufficiently acidic by atmospheric pollution
14. / a glacial episode during a past geological period
15. / an area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding.
17. / the movement of surface material caused by gravity.
18. / a steep-sided mound of sand and gravel deposited by a melting ice sheet.
23. / a curved lake formed at a former oxbow where the main stream of the river has cut across the narrow end and no longer flows around the loop of the bend.
25. / material carried away from a glacier by meltwater and deposited beyond the moraine.
27. / a slowly moving mass or river of ice formed by the accumulation and compaction of snow on mountains or near the poles
