Which coastal landform develops when longshore drift deposits sediment offshore?

💡 Explanation

Longshore drift carries the sediment; **accretion** then forms a depositional feature, like a barrier island, because sediment accumulates faster than erosion can remove it. Therefore, barrier islands are formed, rather than estuaries changing or cliffs eroding, due to this sediment deposition.
