A ________ occurs when the fault plane forms a low angle relative to the horizontal, resulting in the overlying block being shifted over the underlying.
A) lateral fault
B) thrust fault
C) normal fault
D) strike-slip fault

Question

Quizplus · Accepted Answer

Thrust faults occur when the fault plane dips less than 45 degrees relative to the horizontal, causing the overlying block to move up and over the underlying block. This can result in the formation of folds and mountains, and is commonly associated with compressional tectonic settings. Lateral faults (A) and strike-slip faults (D) involve more horizontal movement along the fault plane, while normal faults (C) involve extension and the overlying block moving downward relative to the underlying block.
