The Great Victoria Desert is the largest desert in the continent of Australia and the eight largest desert in the world overall, covering roughly 163900 square miles. It is located in the South-Western region of Australia, stretching from the Eastern Goldfields of Western Australia to the Gawler Ranges in Southern Australia.  It is one of the five deserts and among the many different ecosystems located in the vast but sparsely populated region known as the Australian Outback.

The Great Victoria Desert is considered to be a hot, arid desert, receiving only 150 to 250 mm(5.9 to 9.8 inches) of rain annually.  However the rain tends to be random and unpredictable throughout the year.  Summers can achieve high temperatures reaching temperatures of 35 degrees Celsius and in the winter can reach temperatures below freezing in the middle of the night.

The Great Victoria Desert is mostly covered in sand dunes, especially in the low-elevation areas, dispersed among low ranges, tabletops, and plains.  In other areas, there are special regions called gibber plains, which are regions of the desert completely covered in pebbles. Little vegetation can live in this sort of environment, though during times of rain, some temporary plants will sprout.

Deserts – Overview


http://www.outback-australia-travel-secrets.com/australian_deserts.html
A desert is considered to be one of the driest ecosystems in the world, with the expected rainfall of all deserts reaching only 0 to 20 inches per year.  Many associate the dry climate to the intense heat of a traditional ‘hot’ desert but freezing ‘cold’ deserts do exist, the biggest being the entire continent of Antarctica.  Due to the harsh climate of a desert, the vegetation found in these regions have adapted by either developing leaves and stems that store water, growing long taproots to gather water from deep beneath the surface, or developing spiny ‘leaves’ that give off less moisture than a typical leaf.
