The Biosphere includes all life on Earth including life living on the Earth's Geosphere and in Hydrosphere, including humans and all organic matter that has not yet decomposed. This important sphere distinguishes Earth from all other planets in our solar system as life evolved (and con
Please consider using this graphic organizer to help students analyze the processes and components of Earth System phenomena.
Energy from the Sun is the driver of many Earth System processes. This energy flows into the Atmosphere and heats this system up It also heats up the Hydrosphere and the land surface of the Geosphere, and fuels many processes in the Biosphere.
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.
Students play the role of nitrogen atoms traveling through the nitrogen cycle to gain an understanding of the varied pathways through the cycle and the relevance of nitrogen to living things.
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.
Forests are an important and common feature of the Earth’s land cover, covering 31 percent of the total land surface. There are two regions in particular where forests are common.
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.
NASA Worldview is a free online visualization tool that is a great launchpad for learners who are new (or
Scientific data are often represented by assigning ranges of numbers to specific colors. The colors are then used to make an images which allow us to see patterns more easily. Students will make a false color image using a set of numbers.
