Question

10 a slope that is ____ would most likely produce a mass movement
○ between 25 and 40 degrees
○ less than 25 degrees
○ greater than 40 degrees

Explanation:

Mass movement (like mass wasting) is more likely on steeper slopes. Slopes greater than 40 degrees have high gravitational pull on materials, making mass movement (e.g., landslides, debris flows) more probable. Slopes less than 25 degrees are too gentle, and between 25 - 40 degrees may have some movement but steeper (>40°) is more conducive.

Answer:

C. greater than 40 degrees (assuming the options are labeled as A: between 25 and 40 degrees, B: less than 25 degrees, C: greater than 40 degrees; adjust label if needed, but the correct concept is slopes steeper than ~40° promote mass movement)
