Question

In which type of flowage, failure is not easily perceptible?

(a) Rapid failure

(b) Quick failure

(c) Slow failure

(d) Moderate failure

This question was posed to me in homework.

I want to ask this question from Types of Mass Movements topic in division Mass Movements of Engineering Geology

Answer 1

The correct option is (c) Slow failure

For explanation I would say: Flowage is further distinguished into slow and rapid flowage. In the slow flowage, failure is not easily perceptible. The ground may be moving downslope at such low rates as few centimeters a year or even less.
