Landscape Features: Shorelines

Coastal Processes

Any outing to the beach quickly demonstrates the power of ocean waves come crashing to the shoreline. They break and erode away massive volumes of beach material. But what gets eroded away has to end up somewhere. Waves are the agents of carrying materials away and building up new land elsewhere.  They build up the land and tear it down.

Can you tell which landscape feature below was caused by coastal erosion (tearing down) and which one was caused by coastal deposition (building up)? Roll over each image with your mouse to see clues about how the landscapes formed.
