4th Grade Science Question of the Day

This map shows Fire Island, which is off the coast of Long Island, New York. Fire Island has been studied since the 1800s, and using ariel photos and historical maps, the United States Geological Survey has been tracking both long-term and short-term changes to the island. This map is focused on long-term changes and identifies coastal shoreline changes from 1830 to 2007. Crews have been working to restore part of the island, use the island as a barrier to protect landforms behind it, and create safe conditions for tourists.

Using the legend and provided map describe a pattern that can be identified.
