Question

tectonic stresses can cause rocks to break. the feature produced when broken blocks of rock slide against each other is called a fault.
which rock exposure displays evidence of faulting?
(there are four images labeled a, b, c, d, and multiple - choice options a, b, c, d below the images)

Explanation:

To determine which rock exposure shows faulting, we recall that a fault is a break where rock blocks slide against each other.

• Option A shows folded rock layers (anticlines/synclines), no fault.
• Option B has a distinct break (fault line) with rock layers offset, indicating sliding of blocks—this is faulting.
• Option C shows tilted rock layers, no fault.
• Option D shows an igneous intrusion (like a dike), not faulting.

Answer:

B. The rock exposure with a fault line and offset rock layers
