Regional

In geography, regions, otherwise referred to as areas, zones, lands or territories, are portions of the Earth's surface that are broadly divided by physical characteristics, human impact characteristics, and/or the interaction of humanity and the environment. Geographic regions and sub-regions are mostly described by their imprecisely defined, and sometimes transitory boundaries, except in human geography, where jurisdiction areas such as national borders are defined in law. More confined or well bounded portions are called locations or places. The areal extent of a geographical region is often expressed in square kilometres or hectares.
