10. Kara-Kum Desert, Uzbekistan / Turkmenistan
The Karakum Desert, also spelled Kara-Kum and Gara Gum is a desert in
Central Asia. It occupies about 70 percent, or 350,000 km², of the area
of Turkmenistan. Covering much of present day Turkmenistan, the Karakum
Desert lies east of the Caspian Sea, with the Aral Sea to the north and
the Amu Darya river and the Kyzyl Kum desert to the northeast.
In modern times, with the shrinking of the Aral Sea, the extended “Aral
Karakum” has appeared on the former seabed, with an estimated area of
15,440 sq. The sands of the Aral Karakum are made up of a salt-marsh
consisting of finely-dispersed evaporites and remnants of alkaline
mineral deposits, washed into the basin from irrigated fields. The dusts
blown on a powerful east-west airstream carry pesticide residues that
have been found in the blood of penguins in Antarctica.
Lets read about top ten world’s largest deserts.
9. Great Sandy Desert, Australia
The Great Sandy Desert is a 360,000 km2 (140,000 sq mi) expanse in
northwestern Australia. Roughly the same size as Japan, it forms part of
a larger desert area known as the Western Desert. The vast region
of Western Australia is sparsely
populated, without significant settlements. The Great Sandy Desert is a
flat area between the rocky ranges of the Pilbara and the Kimberley. To
the southeast is the Gibson Desert and to the east is the Tanami
Desert. The Rudall River National Park and Lake Dora are located in the
southwest while Lake Mackay is located in the southeast.
8. Chihuahuan Desert, Mexico
The Chihuahuan Desert is a desert that straddles the U.S.-Mexico border
in the central and northern portions of the Mexican Plateau, bordered on
the west by the extensive Sierra Madre Occidental range, and overlaying
northern portions of the east range, the Sierra Madre Oriental. On the
U.S. side it occupies the valleys and basins of central and southern
New Mexico, Texas west of the Pecos River and southeastern Arizona;
south of the border, it covers the northern half of the Mexican state of
Chihuahua, most of Coahuila, north-east portion of Durango, extreme
northern portion of Zacatecas and small western portions of Nuevo León.
It has an area of about 140,000 square miles. It is the third largest
desert of the Western Hemisphere and is second largest in North America,
after the Great Basin Desert.
7. Great Basin Desert, USA
The Great Basin is the largest watershed of North America which does not
drain to an ocean. Water within the Great Basin evaporates since
outward flow is blocked. The basin extends into Mexico and covers most
of Nevada and over half of Utah, as well as parts of California, Idaho,
Oregon and Wyoming. The majority
of the watershed is in the North American Desert ecoregion, but
includes areas of the Forested Mountain and Mediterranean California
ecoregions. The Great Basin includes several metropolitan areas and
Shoshone Great Basin tribes. A wide variety of animals can be found in
great basin desert. Look to the rocky slopes around the desert mountain
ranges, you may spot a very rare desert bighorn sheep. Other mammals of
the desert include kit fox, coyote, skunk, black-tailed jackrabbit, ground squirrels, kangaroo rat and many species of mice. Bird species are very diverse in desert oases.
6. Great Victoria Desert, Australia
The Great Victoria Desert is a barren, arid, and sparsely populated
desert ecoregion in southern Australia. It falls inside the states of South Australia and Western Australia
and consists of many small sandhills, grasslands and salt lakes. It is
over 700 kilometres (430 mi) wide (from west to east) and covers an
area of 424,400 square kilometres (163,900 sq mi). The Western Australia Mallee shrub ecoregion lies to the west, the Little Sandy Desert to the northwest,
the Gibson Desert and the Central Ranges xeric shrublands to the north,
the Tirari and Sturt Stony deserts to the east, and the Nullarbor
Plain to the south separates it from the Southern Ocean.
5. Patagonia Desert, Argentina
The Patagonian Desert, also known as the Patagonia Desert or the
Patagonian Steppe, is the largest desert in America and is the 7th
largest desert in the world by area, occupying 260,000 square miles
(673,000 km). It is located primarily in Argentina with small parts in
Chile and is bounded by the Andes, to its west, and the Atlantic Ocean
to its east, in the region of Patagonia, southern Argentina. The
Patagonian Desert is the largest continental landmass of the 40°
parallel and is a large cold winter desert, where the temperature rarely
exceeds 12°C and averages just 3°C. The region experiences about seven months of winter and five months of summer.
4. Kalahari Desert, Southern Africa
The Kalahari Desert is a large arid to semi-arid sandy area in Southern
Africa extending 900,000 square kilometers (350,000 sq), covering much
of Botswana and parts of Namibia and South Africa, as semi-desert, with
huge tracts of excellent grazing after good rains. The Kalahari Desert
is the southern part of Africa, and the geography is a portion of desert
and a plateau. The Kalahari supports some animals and plants because
most of it is not a true desert. There are small amounts of rainfall and
the summer temperature is very high. It usually receives 3–7.5 inches
(76–190 mm) of rain per year. The surrounding Kalahari Basin covers over
2,500,000 square kilometers (970,000 sq mi) extending farther into
Botswana, Namibia and South Africa, and encroaching into parts of
Angola, Zambia and Zimbabwe. The only permanent river, the Okavango,
flows into a delta in the northwest, forming marshes that are rich in wildlife.
3. Gobi Desert, Mongolia / N.E China
The Gobi is a large desert region in Asia. It covers parts of northern
and northwestern China, and of southern Mongolia. The desert basins of
the Gobi are bounded by the Altai Mountains and the grasslands and
steppes of Mongolia on the north, by the Hexi Corridor and Tibetan
Plateau to the southwest, and by the North China Plain to the southeast.
The Gobi is made up of several distinct ecological and geographic
regions based on variations in climate and topography. This desert is
the fifth largest in the world. The Gobi is most notable in history as
part of the great Mongol Empire, and as the location of several
important cities along the Silk Road.
2. Arabian Desert, peninsula
Arabian Desert or Eastern Desert, c.86,000 sq mi (222,740 sq km), E
Egypt, bordered by the Nile valley in the west and the Red Sea and the
Gulf of Suez in the east. It extends along most of Egypt’s eastern
border and merges into the Nubian Desert in the south.
The Arabian Desert is sparsely populated; most of its inhabitants are
based around wells and springs. Today most of the desert can be accessed
by roads. Since ancient times Egypt has used the porphyry, granite,
limestone, and sandstone found in the desert mountains as building
materials. Oil is produced in the north. The name Arabian Desert is also
commonly applied to the desert of the Arabian Peninsula.
1. Sahara Desert, North Africa
The Sahara is the world’s largest desert. At over 9,000,000 square
kilometers (3,500,000 sq mi), it covers most of Northern Africa, making
it almost as large as the United States or the continent of Europe. The
desert stretches from the Red Sea, including parts of the Mediterranean
coasts, to the outskirts of the Atlantic Ocean. To the south, it is
delimited by the Sahel: a belt of semi-arid tropical savanna that
comprises the northern region of central and western Sub-Saharan Africa.
