Air quality is a measure of the pollution level in the air. Polluted air can be caused by many things. There are manmade and natural sources of emissions. 

What is sea-level rise and how does it affect us? This "Teachable Moment" looks at the science behind sea-level rise and offers lessons and tools for teaching students about this important climate topic. 

Explore and connect to GLOBE protocol bundles. Each bundle has related Earth System Data Explorer datasets identified.

Phytoplankton distribution background information.

Examine (daytime) surface temperature and solar radiation received at locations found near similar latitudes using NASA Data.

Students categorize causes, effects, and responses to volcanic hazards through an Earth system perspective. They use remotely sensed images to examine the visible effects of the eruption of Mount St. Helens in 1980 and identify a buffer zone for safer locations for development.
