Students examine the two time series images to determine the differences between seasonal ice melt over water versus land.

The ocean's surface is not level, and sea levels change in response to changes in chemistry and temperature. Sophisticated satellite measurements are required for scientists to document current sea level rise.

This activity is one of a series in the collection, The Potential Consequences of Climate Variability and Change activities. 

In this activity students will learn several ways to safely observe a solar eclipse.
