Document Summary
A systems approach considers the interconnections and flows of matter and. Physical geography differs from other sciences in that it often focuses on the energy in natural systems entire system, rather than its components. Important contemporary topics related to physical geography include: Current concerns about rising temperatures and impact on humans and environment. Carbon moves between the atmosphere, oceans, biosphere and human combustion of fossil fuels. Loss of biodiversity has many implications including loss of resources. Degradation of not only freshwater and air, but also oceans and soil. With changes in climate, models predict a higher frequency of extreme. The natural systems studied in physical geography operated within the four great. Global to local (objects, areas, processes dependent on scale) Flow systems of matter and energy (able to determine how systems react to. Regular changes in energy and matter flows in a system that recur in a fixed period of time (e. g. seasonal variations in radiation; lunar orbit- tides)
