How Long Island was carved out by glaciers •

Today’s Image of the Day comes thanks to the NASA Earth Observatory and features a look at how Long Island was carved out by glaciers.

At the conclusion of the last Ice Age, glaciers retreated, which caused sediment to pile up. Then, once the ice melted and sea levels rose, water filled in the areas between the sediment deposits. This is exactly how present day Long Island was created, and the surrounding sea water continues to reshape its shoreline.

This image was captured by the Operational Land Imager (OLI) onboard the Landsat 8 satellite.
