Question

A slope that is _____ would most likely produce a mass movement. less than 25 degrees

between 25 and 40 degrees

greater than 40 degrees

Answer 1

40 not 45*

(greater than 40 degrees)

is the answer:)only slope that works for this option:)

less than 25 degrees

Is incorrect.

between 25 and 40 degrees

Incorrect.

Answer 2

The angle of repose is the steepest angle that a hill or slope can maintain without collapsing - and this is around 25 to 40 degrees.

Therefore a slope that is 45 degrees would most likely produce mass movement.

(Also if you think about it, things are more likely to fall down if the angle is higher anyway)
