Students will analyze a line graph that shows how the surface temperature and air temperature values change over the course of 24 hours.
Review this page to learn about the background of volcanoes and their eruptions.
Students will describe the changes in a newly-formed volcanic island over the first three years of its life.
Students explore albedo, sea ice, and the relationship between changing albedo and changing sea ice using data visualizations.
Students examine satellite images of an island before and after a volcanic eruption to determine the impact of the eruption.
This mini lesson helps students visualize how the Hydrosphere and Cryosphere interact to produce changes in land and sea ice.
Students analyze a graph that illustrates the change in global surface temperature relative to 1951-1980 average temperatures.
Carbon dioxide concentration in the atmosphere is affected by many processes including fires, deforestation, and plant respiration. Students will evaluate a Landsat image to determine the rate of carbon dioxide sequestration in a particular area.
Students examine the two time series images to determine the differences between seasonal ice melt over water versus land.
