What are three physical processes that have influenced the creation of coastal landforms?

Three physical processes that have significantly influenced the creation of coastal landforms are erosion, deposition, and sediment transport. Erosion occurs due to wave action, currents, and weathering, shaping cliffs and beaches. Deposition happens when sediment carried by waves and currents settles, forming features like sandbars and deltas. Additionally, sediment transport, driven by wave energy and tidal movements, redistributes materials along the coastline, contributing to the dynamic nature of coastal environments.
