Question

Quizplus · Accepted Answer

The East Coast is located far from a convergent plate boundary and therefore experiences less tectonic activity. The lack of tectonic activity means that the land is not being pushed up or down rapidly, which allows for more sediment to accumulate on the continental shelf and form wider, sandier beaches. West Coast beaches, on the other hand, are often narrower and rockier due to the region's location near a convergent boundary where tectonic activity is higher.
