Make a model to represent how any two systems, specifically the atmosphere, biosphere, geosphere, and/or hydrosphere, interact and support life.

Please make sure to label and explain how life is being supported by the two systems that you choose.

In what climate does shifting cultivation predominate? and, what are its two characteristics?

How do oceanographers measure the salinity of ocean water?

Sandstones that form in aeolian (wind/desert) environments appear very different from other sandstones, such as those formed in a beach/ shoreline environment and in rivers on land. give three identifying properties for each of the three sandstones that would tell a geologist which depositional environment they formed in. consider things such as the relationship between transportation and grain size, shape, roundness, sorting, fossils and composition.
