KEY CONCEPTS. By the end of this chapter, students should be able to: Explain the defining characteristic of a desert and distinguish between the three broad categories of deserts. Explain how geographic features, latitude, atmospheric circulation, and Coriolis Effect influence where deserts are located.
Explore the fascinating world of desert geology and discover the extraordinary features that make these arid regions unlike any other on Earth. Approximately one-third of the planet’s landmass consists of deserts or semi-desert areas, characterized by distinctive geological formations shaped primarily by wind and water erosion in their harsh ...
While deserts are defined by dryness, not sand, the popular conception of a typical desert is a sand sea called an erg. An erg is a broad area of desert covered by a sheet of fine-grained sand often blown by aeolian forces (wind) into dunes [ 21 ].
Deserts are arid ecosystems that receive fewer than 25 centimeters (10 inches) of precipitation a year. Death Valley, California, above, receives fewer than 5 centimeters (2 inches) of rainfall every year. However, Death Valley's infrequent rain and extreme temperatures can impact the landscape.
Deserts are not randomly located on the Earth’s surface. Many deserts are located at latitudes between 15° and 30° in both hemispheres and at both the North and South Poles, created by prevailing wind circulation in the atmosphere.
Explain how geographic features, latitude, atmospheric circulation, and Coriolis Effect influence where deserts are located. List the primary desert weathering and erosion processes. Identify desert landforms. Explain how desert landforms are formed by erosion and deposition.
