Physiographic province
Encyclopedia
A physiographic province is a geographic region with a specific geomorphology
and often specific subsurface rock type or structural elements.
A continent may be subdivided into various physiographic provinces, each having a specific character, relief, and environment which contributes to its uniqueness.
