The Four Earth Systems, Introduced
Earth can be thought of as four connected systems: the geosphere (rock and soil), the hydrosphere (water), the atmosphere (air), and the biosphere (living things). This course studies each system on its own and then looks at how they affect each other, since a change in one system, like a volcanic eruption adding gas to the atmosphere, often causes changes in the others too.
