OBJ: What are the main components of the Earth System
What is a system? A system is a group of parts that work together as a whole. Earth is a giant system!
Earth System Break down Atmo- (Greek) vapor Hydr- (Latin) water Geo- (Latin) land Bio- (Latin) living
Atmosphere The atmosphere is the outermost layer and a thin blanket of gases surrounding the Earth. Think of the Earth’s weather! Rain and snow form in this sphere.
Geosphere Immediately think of Volcano! The Geosphere includes all the hard surfaces of the Earth and there are 3 parts… Metal Core Solid Middle Layer Rocky outer layer
Hydrosphere Oceans, glaciers, rivers, lakes A estimate of about ¾ of the Earth is covered in WATER. Oceans, glaciers, rivers, lakes What type of water covers most of the Earth’s surface?
Biosphere The biosphere includes all living organisms. The gift of life makes our planet different from other planets in the solar system. How does the Biosphere interact with the Hydrosphere?
Connecting the Earth’s System The 4 spheres are closely connected. The changes in one sphere causes change in others.
