The Thar Desert, also called the Great Indian Desert, covers more than
77,000 square miles (200,000 square kilometres) and forms a natural
border between India and Pakistan. It is a large arid region, with a
landscape dominated by sand dunes varying in size from 52 feet (16
meters) in the North to 498 feet (152m) in the south. The age of the
Thar desert is a topic of great controversy, though most geologists
agree that it is somewhere in the region of 4000-10,000 years old.
The Taklamaklan Desert, also known as the “Place of Ruins” or the “Sea
of Death”, is the largest desert in China, at over 1000km (620mi) long
and 400km (250mi) wide. Lying between the Tien Shan and Kunlun mountain
ranges, the Taklamakan Desert is a waterless death trap. Legend states
that you can get into to the Taklamakan, but you will never get out.
The Mojave is an arid desert, spanning 124,000 sq km (47,877 sq mi).
Primarily situated in California, it also occupies parts of Arizona,
Utah and Nevada. The primary native inhabitants of the area were the
Mojave, though the Paiutes and the Chemehueves were also present.
Today, the majority of the Mojave Desert is sparsely populated, though
it is located between two of the most popular and conventional tourist
cities in the world, Los Angeles and Las Vegas.
The Gobi Desert spans portions of both Northern China and Southern
Mongolia, covering a total area of 1.29 million square kilometers (0.5
million square miles). A cold desert; Gobi has one of the world’s most
extreme climates, featuring rapid temperature changes, both seasonally
and daily. Summer months bring temperatures of up to 122°F (50°C)
whilst in the winter months, temperatures can drop to below -40°F (-40
°C). Rainfall is limited to approximately seven inches annually.
The Atacama Desert, covering a total area of 105,000 sq km (40,541 sq
mi), stretches 1000km (600mi) from southern Peru into northern Chile.
Said to be the driest place on Earth, it receives almost no rainfall
whatsoever. In fact, certain parts of the desert may not experience
rainfall for hundreds of years. As a result of these harsh conditions,
particularly in the lower Atacama Desert, plant and animal life is
almost non-existent. The northern coastal areas, however, do receive a
little more rainfall, and as a result, are less arid.
Death Valley is a desert valley situated within the Mojave Desert. Aptly
named due to its harsh conditions, it is the lowest, hottest and driest
place in the United States. The lowest point is 282ft (82m) below sea
level, and the highest temperature ever recorded was 56.7 degrees
Celcius in 1913. Interestingly, Mount Whitney, the highest point in the
United States, is only 84 miles to the East.
Covering an area of 81,000 km sq (31,274 sq mi), the Namib is a coastal
desert, situated along the southwestern coast of the African continent.
Stretching over 2000km (1200mi), the Namib crosses Angola, Namibia and
South Africa. Characterized by its red sand dunes, that can reach
heights of up to 1200ft (365m) or more, the Namib Desert is considered
to be particularly old, even by geological standards.
Salar de Uyuni is the worlds largest salt flat, spanning 10,582 km2
(4086 m2) in southwestern Bolivia. The Salar de Uyuni is an incredible
landscape, unlike any other desert, featuring vast expanses of
glistening white salt. Underneath the cemented salt are large
reservoirs of lithium-rich brine. In fact, the area is home to 70% of
the world’s lithium reserves.
The Wadi Rum consists of 278 square miles (720 square kilometres) of
desert wilderness. Commonly called ‘The Valley of the Moon’, Wadi Rum
refers to the protected southern Jordan valley that cuts through
variable coloured granite and sandstone mountains. The valley sand
varies in colour from light tan to brick red.
Valley terrain also differs throughout the area, appearing either as
flat and wide or as deep, narrow crevices between rock formations.
The Sahara is the largest hot desert in the world, spanning over 3.6
million square miles and running through several countries in Northern
Africa including Egypt, Morocco, Niger, Chad, Mauritania, Western
Sahara, Sudan, Mali, Algeria and Tunisia. It’s name, ‘Sahara’, is
derived from the Arabic word for ‘desert’. The hottest temperature ever
was recorded in the Sahara Desert - an astonishing 58 degrees Celcius.
The vast majority of the Sahara is a large expanse of sand, though some
mountain ranges and grasslands are present, sparse though they may be.
