Concepts Definitions (Introduction) Geographic Realm: The basic special unit in our world regionalization scheme. Each realm is defined in terms of a synthesis of its total human geography. A composite of its leading cultural economic, historical, political, and appropriate environmental features Region: A device of a real generalization Formal Region: Relatively uniform throughout their area in terms of an identifying criterion or property. Ex: political units, soil distributions, climatic regions Functional Region: A region marked less by its sameness and more by its dynamic internal structure, because it usually focuses on its central node. Ex: newspaper circulation area, retail trade area, labor commuting sheds. Hinterland: The area surrounding the central node of a functional region. Central area produces for the hinterland. Note: Most formal regions and ALL Functional regions have fuzzy boundaries. Well defined boundaries are only seen with political units. Absolute Location: The position or place of a certain item on the surface of the Earth as expressed in degrees, minutes, and seconds of latitude (0-90 N&S of equator) and Relative Location: The regional position or situation of a place relative to the position of other places. Distance, accessibility, and connectivity affect relative location. Scale: The ratio between distance of the map and corresponding distance to the Earth. A large scale will display a small portion of earth in great detail. A small scale will show a large portion of earth in minor detail. Natural Landscape: The Array of landforms that constitutes the Earth’s surface (Mts, hills, plains, etc.) and the physical features that mark them (bodies of water, vegetation, and soils) Each geographic realm has its distinctive combo of natural landscape. Tectonic Plate: Plates are bounded portions of Earth’s mantle and crust. More than a dozen such plates exist, most of continental proportions. The are in motion. Where they meet one slides under the other, crumpling the surface crust and producing significant volcanic and earthquake activity. A major mountain building force. Subduction: the process that occurs when an oceanic plate converges head on with a plate carrying a continental landmass as its leading edge. The lighter continental plate

overrides the denser oceanic plate and pushes it downward. Continental Drift: The slow movement of continents controlled by the process associated with plate tectonics. Theory of Pangea created all continents. (All fit like pieces of a puzzle.) (Laurasia and Gondwana) Urbanization: Movement of people, or clusters of people, into urban cities or towns. Cultural Landscape: The forms and artifacts sequentially placed on the natural landscape by the activities of various human occupants. By this progressive imprinting of the human presence, the physical landscape is modified into the cultural landscape, forming an interacting unity between the two. Globalization:
