Geomorphology

4. – A large, flowing body of water that shapes the land.
9. – The sudden movement of rock and soil down a slope.
11. Tectonics – The theory explaining how Earth's plates move and cause changes to the surface.
12. – A deep valley with steep sides, usually carved by a river.
14. – A sudden shaking of the ground caused by movement along faults.
17. – A bend in rock layers caused by pressure.
18. – A steep face of rock or earth.
19. – A large mass of moving ice that shapes the land.
20. – A high landform formed by tectonic forces or volcanic activity.

1. – A large, flat area of land.
2. – The wearing away of the Earth's surface by wind, water, or ice.
3. – A low area between hills or mountains, often with a river.
5. – An opening in the Earth where lava, ash, and gases erupt.
6. – The breaking down of rocks into smaller pieces.
7. – A landform at the mouth of a river, formed by deposition.
8. – A crack in the Earth's crust where movement happens.
10. – A tall rock formation left behind after erosion removes surrounding rock.
13. – When eroded material is dropped or laid down in a new place.
15. – A raised area of land, smaller than a mountain.
16. – A curved rock feature formed by erosion.
