        Coastline Change

        Observe how a coastline changes over a few decades due to the effects of winds, waves, currents, and tides in this slideshow produced by WGBH. A series of satellite images from NASA shows how the coastline along the southeastern elbow of Cape Cod, Massachusetts evolved over three decades, from 1984 to 2016. Students are able to observe the surface-shaping process of erosion and deposition at a tangible time scale.
