What is the hydrosphere and why is it important?

Students will analyze a graph showing the amounts of peak energy received at local noon each day over the year changes with different latitudes. 

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

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.
