The McMurdo dry valleys of Antarctica, which lack water (whether rain, ice, or snow) much like a non-polar desert and even have such desert features as hypersaline lakes and intermittent streams that resemble (except for being frozen at their surfaces) hot or cold deserts for extreme aridity and lack of precipitation of any kind. Extreme winds ...
The Nama Karoo of Namibia has the world's richest desert fauna. [8] The Chihuahuan desert and Central Mexican matorral are the richest deserts in the Neotropics. [9] The Carnarvon xeric shrublands of Australia are a regional center for endemism. [1] The Sonoran and Baja deserts of Mexico are unusual desert communities dominated by giant ...
Many desert ecosystems are limited by available water levels, rather than rates of radiation or temperature. Water flow in these ecosystems can be thought of as similar to energy flow; in fact, it is often useful to look at water and energy flow together when studying desert ecosystems and ecology. [3]
Across the world, around 20% of desert is sand, varying from only 2% in North America to 30% in Australia and over 45% in Central Asia. [3] Where sand does occur, it is usually in large quantities in the form of sand sheets or extensive areas of dunes. [3] The following sections list deserts around the world, and their explorers.
This is a list of deserts sorted by the region of the world in which the desert is located. Africa. Namib Desert.
The Sechura Desert is a coastal desert located south of the Piura Region of Peru along the Pacific coast and inland to the foothills of the Andes Mountains. Its extreme aridity is caused by the upwelling of cold coastal waters and subtropical atmospheric subsidence , but it is also subject to occasional flooding during El Niño years.
The average annual precipitation in low latitude deserts is less than 250 mm. Relative humidity is very low – only 10% to 30% in interior locations, and even the dewpoints are typically very low, often being well below the freezing mark. Some deserts do not have rainfall all year round, they are located far from the ocean.
