Geography is the science of place and space. Geographers ask where things are located on the surface of the earth, why they are located where they are, how places differ from one another, and how people interact with the environment. Human geography is concerned with the spatial aspects of human existence - how people use and perceive space. Physical geographers study patterns of climates, landforms, vegetation, soils, and water. They forecast the weather, manage land and water resources, and analyze and plan for forests, rangelands, and wetlands.
Geographers also study the linkages between human activity and natural systems.
