If tectonic forces stretch the crust over a large area, many thrust faults may develop, allowing numerous grabens to settle downward along the faults.

Question

Quizplus · Accepted Answer

When tectonic forces stretch the crust, it typically results in the formation of normal faults, not thrust faults. Grabens settle downward between raised blocks called horsts, which are associated with extensional forces and normal faulting, not compressional forces and thrust faulting.
