Question

What is the reason for abrupt termination?

(a) Breaking of strata into blocks

(b) Movement of the disrupted blocks away from each other

(c) Breaking of strata into blocks and movement of disrupted blocks away from each other

(d) Movement of the disrupted blocks towards each other

This question was addressed to me during an online exam.

Query is from Recognition of Faulting topic in division Faults and Faulting of Engineering Geology

Answer 1

The correct option is (c) Breaking of strata into blocks and movement of disrupted blocks away from each other

For explanation I would say: A group of beds or some veins or dykes may abruptly terminate along a surface in a given region. This may generally be due to breaking of the strata into blocks and movement of the disrupted blocks away from each other.
