The advance-and-retreat cycle of snow cover drastically changes the whiteness and brightness of Earth. Using two maps created using NASA satellite data for 2017, students review the seasonal differences of snow and ice extent and answer questions on their observations.

Interpret the map, or model, to find patterns in the occurrence of tropical cyclones from 1842 through 2018.

Because it recognizes the importance of U.S. coastal areas to the nation's economy, the U.S. National Ocean Service has formed a task force that is studying the trends and impacts of hurricanes on coastal regions. They have invited your students to participate.

This activity invites students to model and observe the effect of melting ice sheets (from land) on sea level and the difference between the effect of melting sea-ice to that of melting land ice on sea level.

Learn about volcanic ash and watch a visualization of the Calbuco volcano to see how ash travels around the world. 

In this lesson, students will explore the effect of aerosols on sky color and visibility by using an interactive virtual model. 

In this lesson, students will explore the effect of aerosols on sky color and visibility by using an interactive virtual model. 

Using various visualizations (i.e., images, charts, and graphs), students will explore the energy exchange that occurs when hurricanes extract heat energy from the ocean. This story map is intended to be used with students who have access to a computing device in a 1:1 or 1:2 setting. 

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.

This activity invites students to simulate and observe the different effects on sea level from melting sea-ice.
