(دشت كوير in Persian
), also known as Kavir-e Namak
or Great Salt Desert
is a large desert lying in the middle of the Iranian plateau
. It is about 800 kilometers (497 mi) long and 320 kilometers (198 mi) wide with a total surface area of about 77,600 square kilometers (~30,000 mi²), making it the world's 23rd largest desert
. The area of this desert stretches from the Alborz
mountain range in the north-west to the Dasht-e Lut
("Emptiness Desert") in the south-east and is partitioned between the Iranian provinces
. It is named after the salt marshes (kavirs) located there.
Climate and structure
The Dasht-e Kavir's climate is almost rainless and the area is very arid. Temperatures can reach 50 °C in summer, and the average temperature in January is 22 °C. Day and night temperatures during a year can differ up to 70 °C. Rain usually falls in winter.
The desert soil is covered with sand and pebbles; there are marshes
. The hot temperatures cause extreme vaporization, which leaves the marshes and mud grounds with large crusts of salt. Heavy storms frequently occur and they can cause sand hills reaching up to 40 m in height. Some parts of Dasht- e Kavir have a more steppe
Vegetation in the Dasht-e Kavir is adapted to the hot and arid climate as well as to the saline soil in which it is rooted. Common... Read More
