Describe how longshore drift contributes to sediment deposition along coastlines.

Longshore drift is the process where sediment is transported along the coastline by waves approaching at an angle. As waves break, they move sediment up the beach at an angle, and the backwash pulls it straight back down. This continuous movement results in the gradual deposition of sediment in areas where the wave energy decreases.

This question assesses the student's ability to explain a specific coastal process and its role in sediment deposition. It encourages them to connect the physical dynamics of wave action with the resulting geographical features.
