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
