Helping students build their understanding of Earth's spheres and how they are connected is difficult. Review the graphics below to help identify the parts of the Earth System and the processes that connect them at the local, regional, and global scales.
Please consider using this graphic organizer to help students analyze the processes and components of Earth System phenomena.
NASA Worldview is a free online visualization tool that is a great launchpad for learners who are new (or
The fires in Greece during the summer of 2007 devastated large tracks of forest and ground cover in this Mediterranean region. These before (left) and after (right) images were taken on July 18 and September 4 by Landsat-7. The red areas show the extent of the biomass loss from the fires.
Information from satellites if often used to display information about objects. This information can include how things appear, as well as their contents. Explore how pixel data sequences can be used to create an image and interpret it.
Carbon dioxide concentration in the atmosphere is affected, among other things, by processes involving forests including fires, deforestation and plant respiration. Evaluate a Landsat image to determine the rate of carbon dioxide sequestration in a particular area.
Explore using units in calculations with the Leaf Area Index (LAI). LAI is a ratio that describes the number of square meters of leaves per square meter of available land surface. Because of the units in the ratio, it is dimensionless.
Explore using units for calculations with Normalized Difference Vegetation Index (NDVI). As can be seen through a prism, many different wavelengths make up the spectrum of sunlight. When sunlight shines on objects, certain wavelengths are absorbed and other wavelengths are reflected.
