Environmental geography is the branch of geography dealing with the dynamics of Earth's surface features and their evolution through the actions of weathering and erosion. This type of study is linked to hydrology, environmental geology, and other facets of both geography and geology.
A major part of environmenal geography is the examination of landforms and waterway patterns resulting from the actions of water and streams. This is also referred to in geologic circles as geomorphology.
The link between cultural/environmental geography and geology was at one time very real. As technology has increasingly insulated our cities and commerce from the difficulties presented to communication and transportation by mountains, hills, rivers, and just sheer distance, geomorphology has become less relevant to geography.
Environmental geography represents a critically important set of analytical tools for assessing the impact of human presence on the environment, measuring the result of human activity on natural landforms and cycles.
