Weathering and Mass Movement

4. helps prevent mass movement by binding soil together with roots.
6. action is the breaking of rock by water freezing and expanding in cracks.
7. is the movement of loose material (regolith) down a slope due to gravity.
10. are pillar-like formations that grow from the cave floor.
14. is the physical breaking down of rocks without chemical changes.
15. are deep cracks in limestone pavement caused by carbonation.
16. is when waves or rivers remove the base of a slope, making it unstable.
18. is the fastest type of mass movement, often occurring after volcanic eruptions or heavy rain.
19. is the slowest type of mass movement, causing leaning fences and curved trees.
22. are icicle-shaped formations that hang from the roof of a cave.
24. such as construction, quarrying, and road-building can cause mass movement.
25. is loose material, including soil and rock, that moves in mass movement.
26. is a permeable rock that is easily weathered by carbonation.

1. is the movement of saturated peat downhill, often after heavy rain.
2. is an example of a karst landscape in Ireland.
3. increases the risk of mass movement by removing trees that stabilize slopes.
5. is the breaking down of rocks by chemical reactions.
8. is the breaking down of rock.
9. is a common trigger for landslides and bog bursts.
11. is a rapid movement of soil and rock down a steep slope.
12. are blocks of limestone in a karst landscape.
13. is a weak acid formed when carbon dioxide mixes with rainwater.
17. is the process where rainwater mixes with carbon dioxide to dissolve limestone.
20. is the force that causes mass movement.
21. is a rock characteristic that allows water to pass through it.
23. is a key factor in mass movement, making soil and rock heavy and unstable.
