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 analyze a line graph that shows how the surface temperature and air temperature values change over the course of 24 hours.

Watch NASA videos about aerosols and volcanic ash.

Students analyze a graph that illustrates the change in global surface temperature relative to 1951-1980 average temperatures.

Students watch a NOVA PBS video about the different effects of clouds on climate and Earth's energy budget. Then they answer questions and brainstorm to complete a flow chart of events that might occur if the percentage of absorbing clouds increases.
