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 ...
Salt pan at Lake Karum in Ethiopia. Natural salt pans or salt flats are flat expanses of ground covered with salt and other minerals, usually shining white under the sun.They are found in deserts and are natural formations (unlike salt evaporation ponds, which are artificial).
Deserts and xeric (Ancient Greek ξηρός xērós 'dry') shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. [2] Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less than 250 millimetres (10 in) annually except in the margins.
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]
The modern pan is a chromatically pitched percussion instrument made from 200-litre industrial drums. [4]Drum refers to the steel drum containers from which the pans are made; the steel drum is more correctly called a steel pan or pan as it falls into the idiophone family of instruments, and so is not a drum (which is a membranophone).
The ecoregion extends over the Central Iranian Plateau, which is surrounded by mountain ranges and has no outlets to the sea. Much of the terrain is hot sand-and-gravel desert and large salt flats. The vegetation includes many specialized species of halophytes (salt-tolerant), xerophytes (drought-tolerant), and psammophile (sand-loving) plants.
Due to the highly variable climatic regimes across the Great Plains, many aspects of climate change are not expected to affect all areas of the eco-region equally. In regards to precipitation, this means an exacerbation of extremes where dry areas in the south are expected to get drier and wetter areas in the north to get wetter.
