Question

Quizplus · Accepted Answer

The formation of a flat bench above the west coast is likely due to uplift of the land relative to sea level. This can occur through tectonic processes, such as uplift along a fault line, or through isostatic rebound after the melting of ice sheets or glaciers. Deposition of sediment or transport of delta-derived sediment would not necessarily create a flat bench above the coast, as they would likely result in a sloping or irregular coastline.
