In this activity, student teams explore the connections between parts of the Earth system by examining a time series of environmental data maps. They observe that the environment is the result of the interplay among many processes that take place on varying time and spatial scales, by looking at different six different variables during a single month: insolation, surface temperature, cloud fraction, aerosols, precipitation and biosphere (surface vegetation).
