Which natural agent of erosion is mainly responsible for the formation of the barrier islands along the southern coast of log island New York?

The primary natural agent of erosion responsible for the formation of the barrier islands along the southern coast of Long Island, New York, is ocean waves and currents. These forces continuously shape the coastline by depositing sand and sediment, creating the barrier islands. Additionally, the action of wind contributes to the movement and stabilization of these sandy formations. Over time, this dynamic interaction between water and land has led to the development of the distinctive barrier islands in the region.
