Example of basin and range topography in Nevada (USA). In the foreground a flat valley (basin), in the background a mountain range (range).
A basin and range topography is a geography in geomorphology and geology, where elongated mountain ranges are alternated by valleys. The name comes from the most famous example in western North America, the Basin and Range Province.
Basin and range topographies arise from extensional electronics, a type of motion in the Earth's crust, creating a system of horrors and grabs. The horrors form the mountain ranges (the "ranges", mountain ranges), while the grabens fill with sediment and form the flat valleys (the "basins", geological basins).
This type of topography occurs, for example, in the Basin and Range Province, for example, in southern Spain, in the east of the Betic Cordillera.
