This is one page of notes about Earth Systems and is formatted in the column style notes. It is similar to Cornell Notes. These notes give a simple and brief definition of the Atmosphere Biosphere, Cryosphere, Geosphere, Hydrosphere. This page is meant as in introduction to the Spheres and is an excellent companion to my more detailed notes on the Atmosphere and Water Cycle. These can be used for your reference or for students to copy into their science notebooks. Tons more notes available on different topics and will be coming soon!
