Earth Surface Dynamics
The earth's surface does not exist in a static, unchanging "natural" condition interrupted only by the work of humans, but instead it is a dynamic system of which humans are a part. Knowledge about changes to the Earth's surface and the underlying processes that induce them has enormous impact on how society responds to these changes and, ultimately, the cost of responding to change. USGS Global Change Research activities strive to achieve a whole-system understanding of the interrelationships among earth surface processes, ecological systems, and human activities. Activities of the program focus on documenting, analyzing, and modeling the character of past and present environments and the geological, biological, hydrological, and geochemical processes involved in environmental change so that future environmental changes and impacts can be anticipated.
