This USGS activity leads students to an understanding of what remote sensing means and how researchers use it to study changes to the Earth’s surface, such as deforestation. 

Students develop and test a hypothesis about how albedo affects temperature.

Students explore positive feedback effects of changing albedo from melting Arctic sea ice.

In this activity, students will analyze past and future eclipse data and orbital models to determine why we don’t experience eclipses every month.

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.
