2. A flat sediment-covered area in front of a glacier, formed by the meltwater carrying and depositing sediments.
3. The wearing away of rock surfaces by the friction and impact of rock particles carried by wind, water, or ice
5. The downslope movement of Earth materials (rock, soil, and debris) under the influence of gravity. This can include processes like landslides, mudflows, and slumps.
7. A large mass of ice that moves slowly over land, formed from the accumulation and compaction of snow.
8. A small, steep-sided mound or hill composed of sand and gravel, deposited by glacial meltwater.
10. A slow gradual movement of soil or rock downhill, often imperceptible over short periods. It is caused by factors such as freeze-thaw cycles and the influence of gravity
11. The rapid descent of a large mass of snow, ice, and debris down a mountain slope. Avalanches are often triggered by factors like snowfall, temperature changes, or human activities.
15. A glacier that flows within a valley, typically in mountainous regions.
17. A depression or hole in the ground formed by the melting of a block of glacial ice left behind by a retreating glacier.
20. An elongated, oval-shaped hill formed by glacial action, with the steeper side facing the direction from which the glacier advanced.

1. A massive glacier that covers a significant portion of a continent, also known as an ice sheet.
4. The removal of loose, fine-grained particles (such as sand and silt) from a land surface by wind action, leading to the lowering of the surface
6. Accumulations of rock debris (moraine material) carried and deposited by glaciers.
9. A rapid movement of a mixture of water, rock, soil, and debris down a slope. Mudflows can be triggered by heavy rainfall, volcanic activity, or rapid melting of snow and ice.
12. A bowl-shaped depression carved out by a glacier, often found at the head of a glacial valley.
13. A rock that has been shaped and polished by the abrasive action of wind-blown sand
14. The sudden and fast movement of rock, soil, and debris down a slope. Landslides can be triggered by factors such as heavy rainfall, earthquakes, or human activities.
16. Fine fertile sediment made up of wind-blown silt and clay. It is often deposited over large areas and is valuable for agriculture.
18. A long, winding ridge of sediment deposited by meltwater streams flowing beneath a glacier.
19. A hill or ridge of windblown sand, often found in deserts or coastal areas.
21. A type of mass wasting where a coherent mass of rock or soil moves along a curved surface, typically causing a rotational movement.
