The Physical Environment
Physical geography analyzes the Earth's environment from the perspectives of biogeography, geomorphology and climatology. Physical geographers at MU focus primarily on connections between vegetation, streams, and a changing climate, with a particular emphasis on the human role in modifying these natural systems:
