Great Basin Basin and Range Formation by GreatBasinNP
It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin to the highest point of the contiguous United States, less than 100 miles away at the summit of Mount Whitney.
Badwater Basin is an endorheic basin in Death Valley National Park, Death Valley, Inyo County, California, noted as the lowest point in North America, with a depth of 282 ft below sea level.
Topography is the study of the shape and features of the surface of the Earth and other observable astronomical objects including planets, moons, and asteroids.
The contiguous United States consists of the 48 adjoining U.S. states plus Washington, D.C., on the continent of North America.
The region spans several physiographic divisions, biomes/ecoregions, and deserts.
A biome is a formation of plants and animals that have common characteristics due to similar climates and can be found over a range of continents.
A desert is a barren area of land where little precipitation occurs and consequently living conditions are hostile for plant and animal life.
An ecoregion is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than an ecozone.
