province(redirected from Subprovince)
Also found in: Dictionary, Thesaurus, Legal.
in physical geography, one of the morphological parts of a physiographic region. A province consists of a group of interrelated natural landmarks associated with individual large-scale relief forms (for example, with drainage divides or river valleys and terraces) or with variations in the depth of occurrence of the same type of (pre-Anthropogene) bedrock (for example, karstic limestone under a cover of loess loams). In physiographic science complex systems of similar natural landmarks that have merged in the process of their development (for example, upland swamps in taiga landscapes) and parts of a landscape that differ in the quantitative ratios of areas occupied by different types of natural landmarks (for example, pine forests and swamps in the taiga) with the same qualitative composition are also considered provinces. In geographic literature the term “province” is also used in a general sense to designate an area with a unique combination of natural conditions.
