Match each factor to its impact on slope stability.

Answer:

reduces stability by weakening shear strength of soil and sediment|stabilizes slope by anchoring soil and sediment|reduces stability by lowering cohesion between particles

3

Match each type of mass movement with its definition.

Answer:

slow movement by millimeters or centimeters per year|fast-moving, water-saturated debris|a block of soil that slides down a curved surface|dry rocks tumbling down cliffs or slopes|collapse of surface materials into an empty space below

4

Classify each factor based on whether it increases or decreases slope stability. Drag each factor to the correct box.

5

Classify each event based on whether it is a natural or human-caused trigger for mass movement. Drag each to the correct box.

Answer:

freeze-thaw cycles,earthquakes,heavy rainfall|construction,deforestation,undercutting slopes
