The Valley and Ridge province structurally consists of long rows of folds (synclines and anticlines) and faults, which get expressed as the ridge and valley landforms. What caused these long rows of folds and faults?

Compression due to plate tectonic convergent motion

Explanation:

Folds and faults are formed naturally on land surfaces. Folds are the twists and the bends in the rock surfaces while faults are the planes of detachment which results when the rocks on the either side of displacement slips past one another.

The folds and faults in the Valley and Ridge province are formed due to the plate tectonic convergent movement which occurred during the formation of the Pangea super continent.
