A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation .
Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions that are generally associated with warm temperatures; however ...
Most major kinds of mineral deposits formed by groundwater are located in the deserts. For example, some valuable metallic minerals, such as gold, silver, iron, zinc, and uranium, are found in Western Desert in Australia. This is due to special geological processes, and climate factors in the desert can preserve and enhance mineral deposits. [11]
There are three main deserts in California: the Mojave Desert, the Colorado Desert, and the Great Basin Desert.

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 ...
The Arabian Desert is actually an extension of the Sahara Desert over the Arabian peninsula. The climate is mainly dry. Most areas get around 100 mm (3.9 in) of rain per year. Unlike the Sahara Desert—more than half of which is hyperarid (having rainfall of less than 50 mm (2.0 in) per year)—the Arabian Desert has only a few hyperarid areas ...
The strange monolith looks like it could have come from another world. Jutting out of the rocks in a remote mountain range near Las Vegas, the glimmering rectangular prism's reflective surface ...
The Patagonian Desert is the largest desert south of the 40° parallel and is a large cold winter desert, where the temperature rarely exceeds 12 °C and averages just 3 °C. The region experiences about seven months of winter and five months of summer. Frost is not uncommon in the desert but, due to the very dry condition year round, snow is rare.
