Question

In which type of flowage, failure is easily visible?

(a) Rapid failure

(b) Quick failure

(c) Slow failure

(d) Moderate failure

The question was posed to me by my school teacher while I was bunking the class.

This is a very interesting question from Types of Mass Movements topic in section Mass Movements of Engineering Geology

Answer 1

Correct choice is (a) Rapid failure

To elaborate: In rapid flowage, however, the movement of failing mass may be easily visible and the mass may travel a few metres or more a day. The conditions causing flowage in the two classes may be closely related or entirely different.
