Physical Geography

Climatology, geomorphology, biogeography, arctic and alpine systems, hydrology, and global change

Physical geography integrates and inter-relates landforms, water, soils, climate, and vegetation as the major natural elements of the environment. The focus of physical geography is on the zone of the land, ocean, and atmosphere containing most of the world's organic life. Physical geography not only describes natural phenomena near the surface of the earth but, more importantly, seeks explanations of how and why the physical and biological processes act as they do. Physical geography includes processes studied in other physical and natural sciences such as meteorology, geology, biology, and soil science, however, physical geography is more than a mere composite of these other sciences. It takes a uniquely comprehensive approach to the processes of the natural environment, often with an emphasis on human modifications to the environment.
