This NASA visualization shows sea surface salinity observations (September 2011-September 2014). Students review the video and answer questions.

Students will describe the changes in a newly-formed volcanic island over the first three years of its life.  

Students review an animation of monthly average wind speed at 10 meters above the ocean surface for our global ocean to analyze the relationship between winds and ocean surface currents.

Students interpret a double bar/column chart comparing the number of tropical cyclones in different locations.

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

Compare images from two volcanic eruptions in the Kuril Islands which occurred ten years apart and complete a graphic organizer for impacts on different Earth spheres. 

The Earth System Poster activity walks learners through global patterns and illuminates how each of the spheres is interconnected across the world. We will divide into small groups to look at maps of different parts of the earth system that have been observed by NASA satellites.

Students examine satellite images of an island before and after a volcanic eruption to determine the impact of the eruption.

This learning activity uses data acquired by the TOPEX/Poseidon altimeter, a joint project of NASA and the French Space Agency, to investigate the relationship between the topography of a sea-floor feature and the topography of the overlying sea surface.
