The Eyjabakkajökull Glacier is an outlet glacier of the Vatnajökull ice cap in Iceland that has been retreating since a major surge occurred in 1973. Students analyze these maps to identify the scale and rate of change of the glacier loss.

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. 

Students will review the NASA Space Place video, "Tectonic Forces", and answer questions about tectonic plates.

Review this page to learn about the background of volcanoes and their eruptions.

Students examine satellite images of a recently formed island to identify areas of erosion and deposition.

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

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.
