Coastal Processes

The video explains how coastlines are shaped by three main processes: erosion, transportation, and deposition. Erosion involves the wearing away of land by destructive waves, which can occur through attrition, abrasion, and solution. Transportation refers to the movement of materials along the coast, primarily through longshore drift, which includes solution, suspension, saltation, and traction. Deposition occurs when the sea loses energy and drops the materials it carries, contributing to the formation of diverse coastlines.

What is longshore drift and how does it affect sediment movement?

Define deposition and explain how it occurs with constructive waves.
