Question

which type of fault is under compression?
a. transform
b. thrust
c. normal
d. strike - slip

Explanation:

Thrust faults occur when rocks are compressed. In a thrust fault, the hanging wall moves up and over the footwall due to compressional forces. Transform faults are associated with shear forces (side - to - side movement). Normal faults are due to tensional forces (pulling apart). Strike - slip faults are also related to shear (horizontal sliding) rather than compression.

Answer:

B. Thrust
