In the delta the estuarine soils are excessively saline and barren. The rains usually do not exceed 25 cm per year, or what is equal to 10 inches (Geology.com, 2017). This type of dune has more than two crests (usually 3 or 4) that resemble the arms of a star, which are united in a central point whose height can ascend to 90 meters (Araucania Geological Routes, 2017). They are bounded to the north-west by the Hindu Kush mountain range and to the north by the Karakoram. At night, these areas cool quickly because they lack the insulation provided by humidity and clouds. The surface of the desert is a wild maze of sand dunes and sand ridges. With little vegetation to anchor it, the thin topsoil quickly eroded. Pakistan consists of 5 major deserts in the region. Cities like New York City, New York, and Atlanta, Georgia, can be 5 degrees warmer than the surrounding area. Syllabus: Geography - Physical Geography of the world..

Twinkl 2014 National Curriculum Resources Geography KS2 Geography Curriculum Human and Physical Geography Describe . In fact, the Atacama Desert is the driest place on Earth. Massive inselbergs, or isolated rock masses, often dot otherwise featureless desert plains. When the wind is constant, the shape of the curves is symmetrical. The desert is widely known for its extremely arid climatic conditions. Hydrogen molecules in the fat combine with inhaled oxygen to form water. They are artificial deposits of dry river beds that only fill with water in the rainy season and then dry again when the rainfall ends so they are not long lasting. [7sa6 Good aquifers have been detected in the central part of the desert. Pothohar Plateau is bounded on the east by the Jhelum River, on the west by the Indus River, on the north by the Kala Chitta Range and the Margalla Hills, and on the south by the Salt Range. The Thar Desert The Thar Desert is one of the largest desert of Pakistan. Shaded relief map. Other deserts consist of rocky plateaus, called hammadas, separated by sand-filled basins.

Spas ring the Dead Sea, a saline lake in the Judean Desert of Israel and Jordan. The name Thar is derived from thul, the general term for the regions sand ridges. Your time: 00:01:07. However, water is scarce. The shallow lakes that form in basins eventually evaporate, leaving playas, or salt-surfaced lake beds.

A coastal desert may be almost totally rainless, yet damp with fog.The Atacama Desert, on the Pacific shores of Chile, is a coastal desert. Thus there are three mountain ranges in northern Pakistan: Karakoram, Himalayas and Hindu Kush. The Thar Desert is a vast dry area covering over 200,000 square kilometers.

Found in different regions across the country, the deserts of Pakistan are best-known for their unique features, which also differentiates them from each other. The Cholistan Desert is locally known as Rohi and covers the area ofBahawalpur,Punjab. They are found along the Tropic of Cancer, between 15 and 30 degrees north of the Equator, or along the Tropic of Capricorn, between 15 and 30 degrees south of the Equator.Hot, moist air rises into the atmosphere near the Equator. Most desert birds are restricted to areas near water, such as river banks. The Gobi is also in the rain shadow of the Himalaya mountains to the south.Polar DesertsParts of the Arctic and the Antarctic are classified as deserts. Answer (4) Gobi Desert. Other subtropical deserts include the Kalahari Desert in southern Africa and the Tanami Desert in northern Australia.Coastal DesertsCold ocean currents contribute to the formation of coastal deserts.

Evenings are cool; the diurnal variation in temperature may be as much as 20 to 30 F (11 to 17 C). These spinning columns of dirt can rise hundreds of feet in the air. It has a total area of 175,000 square kilometers that covers the major areas of Pakistan and India. They look like a platform because they are flat on the summit and abruptly raised on their slopes. When the air moves over the mountaintop and begins to descend the leeward slopes, there is little moisture left. Many desert cities, from the American Southwest to the Middle East, rely heavily on such aquifers to fill their water needs. Thar Desert, also called Great Indian Desert, arid region of rolling sand hills on the Indian subcontinent. Fennec fox communities work together to dig large burrows, some as large as 93 square meters (1,000 square feet). Similar lush conditions existed as recently as 25,000 years ago. Air blowing toward shore, chilled by contact with cold water, produces a layer of fog. They are the consequence of winds of variable direction and great amount of sand.

For instance, it offers some of the most amazing views of sand dunes, the beauty of which is amplified by a flawless canopy of blue sky in the background. Deserts are divided into these types according to the causes of their dryness.Subtropical DesertsSubtropical deserts are caused by the circulation patterns of air masses. The major soil groupings are Indus basin soils, mountain soils, and sandy desert soils. However, some birds, such as the roadrunner, have adapted to life in the desert. These oases are supported by some of the worlds largest supplies of underground water. The Dead Sea has had flourishing spas since the time of King David.Air transportation and the development of air conditioning have made the sunny climate of deserts even more accessible and attractive to people from colder regions. Those soils generally are strongly calcareous and have low organic content, but under subhumid conditions their organic content increases. They include both shifting sandy soils and clayey floodplain soils. Fossils and artifacts show that lime and olive trees, oaks, and oleanders once bloomed in the Sahara. The Indus basin soils are mostly thick alluvium deposited by rivers and are of recent origin. 1996 - 2023 National Geographic Society.
