Mapping Ancient Coastlines
In this activity, students use a graph to find sea level at various times in the past, then draw the ancient coastlines onto a bathymetric map by following the depth contours. They should develop an understanding of how to interpret a graph to discern changes in sea level, and an understanding that ancient coastlines parallel the contour lines on a bathymetric map. A materials list, directions, background information, and a printable worksheet are provided. National content standards and links to additional information are also included.
