CheckPoint- Study of Earth The Earth consists of four different subsystems. These subsystems include the  lithosphere, biosphere, atmosphere, and hydrosphere. The lithosphere is the  rocky, outermost layer of the Earth. The biosphere consists of all living or  recently dead organisms on Earth. The atmosphere is the envelope of gases that  surrounds the Earth. The hydrosphere is the all of the bodies of water and ice on  Earth, above ground and below ground. All of these systems work together within  the role of geology. As outlined in Chapter one,  plants get nutrients from the  lithosphere, which then can go into the biosphere. When the plants die, some of

Unformatted text preview: their material may go into the atmosphere, while other material may fossilize and go back into the lithosphere. When the rocks erode, their minerals can become salts in the hydrosphere. Lakes evaporate and then return their salt to the lithosphere. There are different materials being exchanged between the subsystems all the time. And this process is what keeps the cycles going. Salt is an important material that we can get from the hydrosphere. Rocks are important, which comes from the lithosphere. Oxygen is also important which comes from the atmosphere and plants from the biosphere are equally important to people on Earth....
