What Is Geography?
Geography is the spatial study of the earth's surface (from the Greek geo, which means “Earth,” and graphein, which means “to write”). Geographers study the earth's physical characteristics, its inhabitants and cultures, phenomena such as climate, and the earth's place within the universe.
