It is thought that an arid climate began to dominate in the region approximately 55 million years old, before changing to a semi-arid climate 14-18 million years ago. This area is traversed by the Tropic of Capricorn and is mostly flat, although some scenic canyons and elevations are found in some areas, for example in the Moon Valley system. The Namib Desert is southern Africa is a coastal desert. This is due to several factors. The Namib Desert formed during the last glacial thawing period, thousands of years ago, when wind currents shifted and preventing the accumulation of... Our experts can answer your tough homework and study questions. Namib Desert in Africa is a rare place on earth where desert meets the sea. The characteristic red dunes of the Namib Desert have developed over many millions of years. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to 200 kilometres (120 mi) inland to the foot of the Great Escarpment. The Namib Desert. The red sand that forms the dunes was deposited into the Atlantic Ocean from the Orange River. The western Namib gets less rain (5 mm) than the eastern Namib (85 mm). From here the wind carried the red sand inland to form the dunes over time. Coastal regions can experience more than 180 days of thick fog a year. Moisture-laden westerlies from the warm Atlantic Ocean are cooled when they meet this current. They attract a vast number of travellers each year, many of whom aim to climb up the sands and enjoy a thrilling slide back down. The complexity and regularity of dune patterns in its dune sea have attracted the attention of geologists for decades, but it remains poorly understood. Covering an area of 31,274 sq. The Namib is regarded as the world's oldest desert as it has experienced arid to semi-arid conditions for around 55 to 80 million years. At 55 million years old, Namib is considered the oldest desert on Earth. Quiz yourself on deserts! Today, these peoples' rock paintings and engravings are to be seen at various sites throughout the Namib Desert. According to the broadest definition, the Namib stretches for more than 2,000 kilometres (1,200 mi) along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. How was the Namib Desert formed? The Namib Desert is home to a number of unusual species of plants and animals that are found nowhere else in the world. [1] Temperatures along the coast are stable and generally range between 9–20 °C (48–68 °F) annually, while temperatures further inland are variable—summer daytime temperatures can exceed 45 °C (113 °F) while nights can be freezing. The Namib Desert extends for some 2000 km along the Atlantic coast of southern Africa from the Olifants River in South Africa (latitude 32°S) to the Carunjamba River in Angola (latitude 14°S). Standing atop one of the tallest dunes on Earth, it felt as though the sand beneath our feet stretched into infinity. Thick sea fog blows in from the ocean and covers the dunes. Deserts are formed on the leeward side of mountain ranges. [1][8] These rivers arise in the interior mountains of Namibia and flow after summer rain storms.[1]. The southeastern coastline of Africa receives very little rainfall. Location and Values: The Namib Sand Sea lies at the heart of the Namib, a coastal fog desert on Africa’s South Atlantic coast in Namibia. So why is it known for its foggy mornings, when fog is made up of water droplets in the air? Welwitschia is notable for its survival in the extremely arid conditions in the Namib, mostly deriving moisture from the coastal sea fogs. Namibia’s interior is a high plateau even today. The foundation is an ancient sand sea that has existed for about 21 million years. From here the wind carried the red sand inland to form the dunes over time. Namib-Naukluft National Park is the focal point of the Namib Desert for tourists. How much of Antarctica does Australia own? Is Antarctica north or south of the Equator? It was formed naturally due to the little precipitation. © copyright 2003-2020 Study.com. It extends inland from the Atlantic Coastline to the foot of the Namib Escarpment, a distance of between 80 and 200 km. It reaches inland 80 to 100 miles (130 to 160 km) to the foot of the Great Escarpment. About 46% of the countryʼs surface are bedrock exposure, while the remainder is covered by the young overburden sediments of the Kalahari and Namib deserts. Eastern Namibia is also dry, though slightly less so. All other trademarks and copyrights are the property of their respective owners. It occupies an area of around 80,950 km2[6] (31,200 square miles), stretching from the Uniab River (north) to the town of Lüderitz (south) and from the Atlantic Ocean (west) to the Namib Escarpment (east). The Advanced Spaceborne Thermal Emission and Reflection Radiometer on NASA’s Terra satellite captured this image on May 7, 2007. It was formed naturally due to the little precipitation. Most of the rest of the desert is set aside for conservation. The Namib Desert formed during the last glacial thawing period, thousands of years ago, when wind currents shifted and preventing the accumulation of... See full answer below. [5] Fogs that originate offshore from the collision of the cold Benguela Current and warm air from the Hadley Cell create a fog belt that frequently envelops parts of the desert. [5] Most of the desert wildlife is arthropods and other small animals that live on little water, although larger animals inhabit the northern regions. Coordinates: 24°45′07″S 15°16′35″E / 24.75194°S 15.27639°E / -24.75194; 15.27639, Approximate boundaries of the Namib Desert, "Chapter 17: Namib Sand Sea: Large Dunes in an Ancient Desert", "Africa by Toto to play on eternal loop 'down in Africa, "Toto forever: Africa to play 'for all eternity' in Namib desert", https://en.wikipedia.org/w/index.php?title=Namib&oldid=985147067, Short description is different from Wikidata, Articles containing Portuguese-language text, Articles containing Khoekhoe-language text, Wikipedia articles with WorldCat-VIAF identifiers, Creative Commons Attribution-ShareAlike License, This page was last edited on 24 October 2020, at 07:20. Most of the Kalahari Desert is covered with vegetation and is described as Savannah. The history of a desert can be studied through palaeontology. The erosion of soft stone formations created the sand masses. The Namib Desert is a coastal desert primarily locatedin Namibia, Africa, and is one of the largest coastal deserts in the world, according to the United Nations Educational, Scientific and Cultural Organization (UNESCO). The exact location of the installation has not been disclosed.[10][11]. All along the coast, but mostly in the northernmost part of it, interaction between the water-laden air coming from the sea via southerly winds, some of the strongest of any coastal desert, and the dry air of the desert causes immense fogs and strong currents. The Namib is a coastal desert in southern Africa. How do plants and animals survive in the Namib... Deserts are hot during the day and cold at night.... What is the national animal of Antarctica? It stretches along the wouthwest coast of Africa from Angola in the north, through Namibia, into South Africa. A few Nama Khoikhoi still graze their livestock on the banks of the Kuiseb River in the desert. Namibia's varied geology encompasses rocks of Archaean to Phanerozoic age, thus covering more than 2600 million years of Earth history. Aquatic Ecosystems: Characteristics & Definition, Desert Ecosystems: How Biodiversity Impacts Hot and Cold Deserts, What is a Terrestrial Ecosystem? Annual precipitation here ranges from 0.079 in to 7.9 in. It was formed approximately sixty million years ago along with the rest of the African continent. Annual precipitation here ranges from 0.079 in to 7.9 in. This causes to release their over the sea. It rises … The Namib Desert is southern Africa is a coastal desert. Blowing inland northwest, winds caused a distribution of the sand and the formation of the dunes. Create your account. The Benguela current then carried this sand northwards, to be deposited back onto the land by the ocean’s surf. The Namib Desert is one of the 500 distinct physiographic provinces of the South African Platform physiographic division. The national park is the combination of the Namib Desert, thought to be the world’s oldest desert, and the Naukluft Mountains, which serve as a sanctuary for endemic Hartmann zebras. The Namib Desert is dry even for a desert! Eastern Namibia is also dry, though slightly less so. Most scientists agree that the Gobi Desert formed when the Himalayan mountain range and the Tibetan plateau took shape about 45 million ... the Namib is one of the driest deserts and is mostly uninhabited by humans. The rims of the African fragment rose and the drop to sea level increased. All rights reserved. The Namib Desert lies along the coastline of southwestern Africa, where the land meets the Atlantic Ocean. A vast portion of the desert, called the Sperrgebiet, was access-restricted due to the presence of diamonds, which are mined in the area at the mouth of the Orange River. Sahara Desert Formed 7 Million Years Ago, New Study Suggests. They are the longest-lived leaves of any member of the plant kingdom. So why is it known for its foggy mornings, when fog is made up of water droplets in the air? There are sand deserts, called erg, rock deserts, called hammada, and pebble deserts, the serir. The lighter sand on the crest of the dune is continually reshaped by the … The Namib Desert stretches from the northern Cape Province of South Africa up along the Atlantic coast of Namibia and northwards into southern Angola. The landscapes that can be admired are truly breathtaking and represent the quintessence of the Namib Desert. Namib means ‘open space’, and the Namib Desert offered its name to help create ‘Namibia’, which means ‘land of open spaces’. When moisture-laden air hits the mountain range, it rises, cools and precipitates on the windward side. [1][2][3] The Namib's northernmost portion, which extends 450 kilometres (280 mi) from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. 3 days itinerary – Sossusvlei & Deadvlei excursion DAY 1 – From Swakopmund to Sesriem (Desert Camp) The tour leaves from A La Mer Hotel in Swakopmund, a city with German colonial architecture located on the coast of Namibia.The closest airport is 40 minutes away in Walvis Bay (WVB Airport) and you need to get there on the day before the tour begins.

The Namib fauna mostly comprises arthropods and other small animals that can live on little water, but a few species of bigger animals are also found, including antelopes (such as oryxes and springboks), ostriches, and in some areas even desert elephants. It may have different geological conformations – mainly due to the effect of the wind (wind erosion). mi (81,000 sq. 1. recent questions recent answers. The southern portion merges with the Kalahari on the plateau atop the escarpment. The steppes in the southern half of the desert are mostly made up of ranches run by Europeans, who raise Karakul sheep with local help and send the wool of the lambs to Europe for use in fur coats. It causes sailors to lose their way; this is testified by the remnants of a number of shipwrecks that can be found along the Skeleton Coast, in northern Namib. According to research, the star dunes migrate up to 10 meters per year. This part of the country holds part of the expansive Kalahari Desert, home to some visually striking dunes.. The Namib desert is regarded as one of the oldest desert in the world. It is inhospitable due to its extreme weather, yet, a few special animals have managed to adjust to its environment. The name Namib is of Khoekhoegowab origin and means "vast place". You may picture sand and dunes when you think of a desert, but deserts can occur in colder areas too. Namib and Kalahari Desert. This ancient desert lies between the icy Atlantic Ocean and the escarpment of Namibia's interior plateau. Here, Lottie Gross flies along the Atlantic coast and over the dunes for a new perspective on this incredible environment. But how much do you know about the Namib sand dunes? Deserts cover a vast area of our continents and they usually form over regions with specific geographic characteristics. The Namib, which believed to be the world's oldest desert, stretches from the Orange River in the south to the Angolan border in the north stretches for 2,080km (1,300mi) It is never more than 160km (100mi) wide. 120–200 km wide, sandwiched between the Great Escarpment and the sea (see Goudie, 2002, Chapter 6 , for an introduction). The Namib's aridity is caused by the descent of dry air of the Hadley Cell, cooled by the cold Benguela current along the coast. Deserts are formed on the leeward side of mountain ranges. The Swakop and the Omaruru are the only rivers that occasionally drain into the ocean. It is a vast area of spectacular sand dunes, featuring two super-imposed systems – an ancient (semi-consolidated) one below, with an active one above. These leaves may grow to be several meters long and over time become gnarled and twisted from the desert winds. Geologists believe that the Namib Desert is the world’s oldest desert. The Namib-Naukluft National Park, that extends over a large part of the Namib Desert, is the largest game reserve in Africa and one of the largest of the world. This ancient desert lies between the icy Atlantic Ocean and the escarpment of Namibia's interior plateau. Moçâmedes in Angola, and Lüderitz, Walvis Bay and Swakopmund in Namibia, bordering on the desert, are the main settlements in the area. In this image, captured on 27 October 2019, a large portion of the Namib-Naukluft National Park is visible. Some beetles extract moisture from trenches made in dunes. In the Sossusvlei area, several dunes exceed 300 meters (980 feet) in height. The Namib desert is an important location for the mining of tungsten, salt and diamonds. The geology of Namibia encompasses rocks of Paleoproterozoic, Mesoproterozoic and Neoproterozoic and Paleozoic to Cenozoic age. The Namib desert is regarded as one of the oldest desert in the world. The Namib Desert averages less than 0.5in (12mm) of rain each year. Gravel plains of the Central Namib occur between the Kuiseb (south) and Ugab (north) ephemeral rivers. When moisture-laden air hits the mountain range, it rises, cools and precipitates on the windward side. The sand dunes, some of which are 300 metres (980 ft) high and span 32 kilometres (20 mi) long, are the second largest in the world after the Badain Jaran Desert dunes in China. (Image credit: Mike and Ann Scott of the Namib Rand Nature Reserve) Few researchers have studied fairy circles, in part because of their remoteness, 111 miles (180 km) form the nearest village. Southern Namib (between Lüderitz and the Kuiseb River) comprises a vast dune sea with some of the tallest and most spectacular dunes of the world, ranging in color from pink to vivid orange. From its source the Gariep (Orange) River dug ever deeper into the earth and the Fish River, its tributary, followed suit on the high plateau in southern Namibia as the continent rose. The Namib Desert ecoregion extends along the coastal plain of western Namibia, from the Uniab River in the north to the town of Luderitz in the south. The desert geology consists of sand seas near the coast, while gravel plains and scattered mountain outcrops occur further inland. The sand sea consists of two dune seas, one on top of the other. An area where Welwitschias are a common sight is found in the surroundings of the Moon Valley, including the eponymous Welwitschia Plains. Access to the park is either by gravel roads or dust roads (except for 60 km of concrete road from the Sesriem gate to Sossusvlei) or by light aircraft from Windhoek (the capital of Namibia, about 480 km (300 mi) north-east of the centre of the desert), or Swakopmund and Walvis Bay at the north end of the desert. In the desert areas, the Namib and the Kalahari, only little rainfall can be expected, with the Kalahari receiveng higher rainfalls than the Namib. Warm waters with depth and associated water flows from the northwest were first fully catalogued by Sea Fisheries researchers, Cape Town (L V Shannon et al.). A number of unusual species of plants and animals are found in this desert, many of which are endemic and highly adapted to the specific climate of the area. Sciences, Culinary Arts and Personal Nevertheless, Namibia is not a country for the typical beach holiday as the water temperatures of the Atlantic rarely rise above 19° C and if they do then only during January – March. The dry climate of the Namib reflects the almost complete lack of bodies of water on the surface. Winds coming from the Indian Ocean lose part of their humidity when passing the Drakensberg mountains, and are essentially dry when they reach the Namib Escarpment at the eastern end of the desert. So the shallow meander belt cut into the sediments and underlying basement rock and the Fish River’s winding system of gorges developed. The 2015 film Mad Max: Fury Road filmed there. The characteristic red dunes of the Namib Desert have developed over many millions of years. The Namib Desert is a harsh biome to live in, but organisms have still adapted to life there and formed their own unique ecosystems. The Kalahari Desert has the largest continuous stretch of sand on earth with sand dunes stretching westward to where it meets the Namib Desert. Black-backed jackals lick humidity from stones. A fog desert is a type of desert where fog drip supplies the majority of moisture needed by animal and plant life.. Characterised by red sand dunes that can reach impressive heights, the Namib is considered to be particularly old, even by geological standards. In 2019 the Namibian-German artist Max Siedentopf created an installation in the Namib consisting of a ring of large white blocks atop of which sit six speakers attached to a solar-powered MP3 player configured to continuously play the 1982 song "Africa" by the American band Toto. The Namib Desert stretches from the northern Cape Province of South Africa up along the Atlantic coast of Namibia and northwards into southern Angola.

The reserve was founded in 1907 after the German Colonial Administration declared the region between the Swakop River and the Kuiseb River a game park. The red parallel dunes with wind-shaped sand ridges were stabilised through vegetation and are so typical of the landscape in the Kalahari. To the south, the Namib borders on the South African Karoo semi-desert. Today, some Herero still herd their livestock in the Kaokoveld in the Namib and take them from waterhole to waterhole. The Benguela current then carried this sand northwards, to be deposited back onto the land by the ocean’s surf. The research noted the positive effect of Benguela's El Niño on the rainfall of the interior. The Namib Desert is a parched and rippled desert, an endless expanse. The park was formed by merging several regions (Namib, Naukluft, Sossusvlei/Sesriem, and Sandwich Harbour). Some of these wrecked ships can be found as much as 50 metres (55 yards) inland, as the desert slowly moves westwards into the sea, reclaiming land over a period of many years. The Namib dunes are among the most stable representatives of their kind rising from the 100 meter high sand dunes in Tsondab said to have been created from 20-40 million years ago and then fossilized. Rainfall records also show positive values variously across the Namib, Desert Research Station, Gobabeb for instance. About half of the country's surface area is bedrock exposure, while the remainder is covered by Cenozoic deposits of the Kalahari and Namib Deserts. Before the 20th century, some San roamed the Namib, gathering edible plants on the shore, hunting in the interior, and drinking the juice of the tsamma melon for water. The source of the unconsolidated sand (the most recent sand sea) has been shown to be dominantly from the Orange River, which drains into the Atlantic south of the Namib Sand Sea, with minor contributions in the east from the (now ephemeral) rivers that drain into the sand sea. Answer for question: Your name: Answers. Standing atop one of the tallest dunes on Earth, it felt as though the sand beneath our feet stretched into infinity. Much of this knowledge about the animals of the Namib Desert is made possible by a research institute in the desert that was established in 1963. Firstly about the Namib Naukluft Park: This conservation area within the oldest desert worldwide, the Namib, is situated along the Atlantic coast, covers an area of nearly 50,000 km² and is the largest protected area in the country. This part of the country holds part of the expansive Kalahari Desert, home to some visually striking dunes.. answer! The earliest evidence of humans living in the desert has been dated to during the late Stone Age era. The Advanced Spaceborne Thermal Emission and Reflection Radiometer on NASA’s Terra satellite captured this image on May 7, 2007. The Namib Desert may be the best-known desert in Namibia, but it is not the only one. It is approximately 2000km long and stretches from the Oliphant’s River in South Africa all the way through Namibia and up to the San Nicolau River in Angola, averaging around 200km wide. Most scientists agree that the Gobi Desert formed when the Himalayan mountain range and the Tibetan plateau took shape about 45 million ... the Namib is one of the driest deserts and is mostly uninhabited by humans. The foundation is an ancient sand sea that has existed for about 21 million years. The national park is the combination of the Namib Desert, thought to be the world’s oldest desert, and the Naukluft Mountains, which serve as a sanctuary for endemic Hartmann zebras. From its source the Gariep (Orange) River dug ever deeper into the earth and the Fish River, its tributary, followed suit on the high plateau in southern Namibia as the continent rose. The sand sea consists of two dune seas, one on top of the other. The Namib Desert may be the best-known desert in Namibia, but it is not the only one. Benguela's El Niño (similar to the Pacific event in its environmental change in the seas) spreads from the Kunene estuary southward to, on occasion, south of Luderitz. Namibia's yearly weather cycle . [1][4] While this has proved a major hazard to ships—more than a thousand wrecks litter the Skeleton Coast—it is a vital source of moisture for desert life. Most moisture falls as rain before it reaches the land, eg the Namib Desert in Africa. - Definition, Types & Stages, Earth's Deserts: Definition, Distribution & Location, Desert Animal Adaptations: Lesson for Kids, Desert Biomes: Facts, Climate & Locations, Human Anatomy & Physiology: Help and Review, Middle School Life Science: Help and Review, UExcel Anatomy & Physiology: Study Guide & Test Prep, CSET Science Subtest II Life Sciences (217): Practice & Study Guide, AP Environmental Science: Help and Review, Praxis Chemistry (5245): Practice & Study Guide, STAAR Science - Grade 8: Test Prep & Practice, NES General Science (311): Practice & Study Guide, UExcel Science of Nutrition: Study Guide & Test Prep, Middle School Earth Science: Help and Review, NYSTCE Biology (006): Practice and Study Guide, Biological and Biomedical The Namib Desert is believed to be one of the oldest deserts in the world, having existed for over 55 million years. The desert is also home to meerkats and several species of lizards. Morning fogs coming from the ocean and pushing inwards into the desert are a regular phenomenon along the coast, and much of the life cycle of animals and plants in the Namib relies on these fogs as the main source of water. Add in a bit of wind to accelerate evaporation at the surface, and the continental regions below become extremely arid owing to the lack of available moisture. Gemsboks (also known as oryxes) can raise the temperature of their bodies to 40 °C in the hottest hours of the day. Whereas the Namib Desert runs along the country’s so-called Skeleton Coast and is distinguished by its looming dunes in a variety of hues from maroon to apricot, the Kalahari Desert (the setting of the movie "The Gods Must Be Crazy") is an inland expanse shared with South Africa and Botswana. Although the outer Namib is largely barren of vegetation, lichens and succulents are found in coastal areas, while grasses, shrubs, and ephemeral plants thrive near the escarpment. The Namib dunes consist of colored quartz sand and shimmer in different colors, the more intense the shade of red the older the dune is. For instance, the coastal desert of Peru and northern Chile washed by the cold Antarctic current of the Hudson and the Namib desert, washed by the Antarctic current of the Banguela. One of the most well-known endemic plants of the Namib is the bizarre Welwitschia mirabilis; a shrub-like plant, it grows two long strap-shaped leaves continuously throughout its lifetime. It stretches for over 2,000 km along the Atlantic Ocean coast of Angola, Namibia, and South Africa. The Namib Desert is long (2,000 km) and narrow (50–150 km), bounded by the Atlantic Ocean on the west and the Great Escarpment of southern Africa on the east (Henschel & Lancaster, 2013). Near the coast, the cold ocean water is rich in fishery resources and supports populations of brown fur seals and shorebirds, which serve as prey for the Skeleton Coast's lions. The park covers an area of almost 50 000 sq km and encompasses part of the Namib Desert and the Naukluft Mountains to the east. The park was formed by merging several regions (Namib, Naukluft, Sossusvlei/Sesriem, and Sandwich Harbour). The Namib (/ˈnæmiːb/; Portuguese: Namibe) is a coastal desert in southern Africa. The seemingly endless recurring pattern of dunes in the Namib Desert formed and reformed by the east wind - Acquista questa foto stock ed esplora foto simili in Adobe Stock Desert. [3] Owing to its antiquity, the Namib may be home to more endemic species than any other desert in the world. A desert forms when there has been a shortage of rain for a long time. One of these is Welwitschia mirabilis, a shrub-like plant that grows just two long leaves continuously throughout its lifetime. [1] Annual precipitation ranges from 2 millimetres (0.079 in) in the most arid regions to 200 millimetres (7.9 in) at the escarpment, making the Namib the only true desert in southern Africa. Quiz yourself on deserts! The Namib's northernmost portion, which extends 450 kilometres (280 mi) from the Angola-Namibia border, … Covering 81,000 square kilometres, its vastness can only truly be appreciated from above. In addition, winds are responsible for the ongoing reshaping of the landscape: they play a key role in that there's virtually no vegetation at all and the ground is easy to attack. Deserts cover a vast area of our continents and they usually form over regions with specific geographic characteristics.
