The Earth is made up of four subsystems. These subsystems are known as; lithosphere, biosphere, atmosphere, and hydrosphere. All four of these subsystems interact together, and play important parts in geology. The Earth’s plants remove and draw nutrients from the lithosphere. These nutrients then incorporate them into the biosphere. Plants die and decompose, when this happens some of the material may enter the atmosphere. The other parts of these dead or decomposed plants may fossilize and reenter the lithosphere. When rocks erode the minerals they contain becomes salt in the hydrosphere. The lakes evaporate their salts back into the lithosphere. These four subsystems all work together and we all depend on them. Each group also

Each of these subsystems contains their own sections. The lithosphere is made up of solids such as the Earths rocks and any solid on the surface of the Earth. The biosphere is made up of all the Earths living things. The atmosphere is the Earths air. The hydrosphere is made up of liquids, gases, and water. These four subsystems work together and make the Earth a livable place....
