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

Watch NASA videos about aerosols and volcanic ash.

Students model Earth's tectonic plate movement and explore the relationship between these movements and different types of volcanoes.

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

This activity introduces students to aspects of the atmosphere, biosphere, hydrosphere, and litho/geosphere and how they are interrelated. It is designed to promote an interest in authentic investigations of Earth using images acquired by astronauts as the hook.

Students will observe monthly satellite data of the North Atlantic to identify relationships among key science variables that include sea surface salinity (SS), air temperature at the ocean surface (AT), sea surface temperature (ST), evaporation (EV), precipitation (PT), and evaporation minus pre
