"Geography is the study of the diverse environments, places, and spaces of the Earth's surface and their interactions. The modern academic discipline of geography is rooted in ancient practice, concerned with the characteristics of places, in particular their natural environments and peoples, as well as the interrelations between the two. Discussion of an area's geography usually refers to its topography - its relief and drainage patterns and predominate vegetation, along with climate and weather patterns - together with human responses to that environment, as in agriculture, industrial, and other land uses in settlement and urbanization patterns."
