Explore using units for calculations with Normalized Difference Vegetation Index (NDVI). NDVI is a ratio of different light wavelength reflectance which can be used to map the density of green vegetation.
Review this page to learn about the background of volcanoes and their eruptions.
Students examine satellite images of an island before and after a volcanic eruption to determine the impact of the eruption.
Students analyze surface air temperature anomalies to identify change with respect to different latitudes across the world.
In this mini lesson, students analyze a bar graph showing the relative forcings from natural and human factors that affect Earth's climate. They use information from this graph to assess the relative importance of these factors.
