Question

Another class of active faults is created by southern California pushing into the "Big Bend" of the San Andreas Fault; these faults are ________.

a) Transform faults
b) Thrust faults
c) Normal faults
d) Strike-slip faults

Answer 1

The faults created by southern California pushing into the "Big Bend" of the San Andreas Fault are thrust faults (b).

Step-by-step explanation:

The faults created by southern California pushing into the "Big Bend" of the San Andreas Fault are thrust faults (b).

Thrust faults occur when one rock mass is pushed up and over another rock mass due to compression. In this case, the compression of southern California into the Big Bend of the San Andreas Fault has created a series of thrust faults.

For example, the San Gabriel Mountains in southern California were uplifted by thrust faults, where older rocks were thrust over younger rocks.
