Kavir Buzurg
Kavir Buzurg, meaning Great Kavir (great salt marsh), lies in the center of the Dasht-e Kavir, which is a desert located in the middle of the Iranian plateau. The Kavir Buzurg covers an area of about 320 km by 160 km. It is separated from the neighboring kavirs by a surrounding ring of sandy hills. This is located in a rain shadow desert that receives little moisture. When water evaporates from the salt marsh A salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is domin ...es, it creates crusts of salt that covers a dark saline mush. These crusts are easily penetrated by a traveler, making journeying across the kavir dangerous. This region is nearly uninhabited, with humans primarily dwelling on the surrounding hills and mountains. References {{reflist, refs= {{cite book , first=Natha ...

Dasht-e Kavir
Dasht-e Kavir ( fa, دشت كوير, lit=Low Plains in classical Persian, from ''khwar'' (low), and ''dasht'' (plain, flatland)), also known as Kavir-e Namak () and the Great Salt Desert, is a large desert lying in the middle of the Iranian Plateau. It is about long by wide with a total surface area of about , making it the world's 24th largest desert. The area of this desert stretches from the Alborz mountain range in the north-west to the Dasht-e Lut in the south-east. It is partitioned among the Iranian provinces of Khorasan, Semnan, Tehran, Isfahan and Yazd. Features In the center of the desert lies the Kavir Buzurg (Great Kavir), which is about 320 km long and wide. In the western part of the desert lies the Daryahcheh-e Namak ("salt lake"), . It contains some large salt plates in a mosaic-like shape. It is part of a protected ecological zone, the Kavir National Park. One of the most desolate parts of Dasht-e Kavir is the Rig-e Jenn (‘ Dune of the Jinn’) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iranian Plateau
The Iranian plateau or Persian plateau is a geological feature in Western Asia, Central Asia, and South Asia. It comprises part of the Eurasian Plate and is wedged between the Arabian Plate and the Indian Plate; situated between the Zagros Mountains to the west, the Caspian Sea and the Köpet Dag to the north, the Armenian Highlands and the Caucasus Mountains to the northwest, the Strait of Hormuz and the Persian Gulf to the south, and the Indian subcontinent to the east. As a historical region, it includes Parthia, Media, Persis, and some of the previous territories of Greater Iran."Old Iranian Online" University of Texas College of Liberal Arts (retrieved 10 February 2007) The Zagros form the plateau's western boundary, and its eastern slopes may also be included in the term.

Rain Shadow
A rain shadow is an area of significantly reduced rainfall behind a mountainous region, on the side facing away from prevailing winds, known as its leeward side. Evaporated moisture from water bodies (such as oceans and large lakes) is carried by the prevailing onshore breezes towards the drier and hotter inland areas. When encountering elevated landforms, the moist air is driven upslope towards the peak, where it expands, cools, and its moisture condenses and starts to precipitate. If the landforms are tall and wide enough, most of the humidity will be lost to precipitation over the windward side (also known as the ''rainward'' side) before ever making it past the top. As the air descends the leeward side of the landforms, it is compressed and heated, producing foehn winds that ''absorb'' moisture downslope and cast a broad "shadow" of dry climate region behind the mountain crests. This climate typically takes the form of shrub–steppe, xeric shrublands or ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Marsh
A salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection. Salt marshes have historically been endangered by poorly implemented coastal management practices, with land reclaimed for human uses or polluted by upstream agriculture or other industrial coastal uses. Additionally, sea level rise caused by climate change is endangering other marshes, through erosion and submersion of otherwise tidal marshes. However, r ...
