Largest Deserts on Earth

Have You Ever Questioned to Yourself, What's Earth largest unfriendly terrain ?

A desert is a barren area of land where little precipitation occurs and consequently living conditions are (literary) hostile for plant and animal (and also human) life. Deserts are not necessarily completely devoid of vegetation, but have large areas where vegetation is very limited in height or extent.

An Illustration about a Desert

The Largest Desert Known is the Sahara, The Sahara Itself is an Arabic word for desert. Spread more than 9.400.000 square kilometers, It's Contains One of the most Thick sand dunes Some of the sand dunes can reach 180 meters in height.

The Sahara's boundaries are the Atlantic Ocean on the west, the Atlas Mountains and the Mediterranean on the north, the Red Sea on the east, and the Sudan and the valley of the Niger River on the south. The Sahara is divided into western Sahara, the central Ahaggar Mountains, the Tibesti Mountains, the Aïr Mountains (a region of desert mountains and high plateaus), Ténéré desert and the Libyan Desert (the most arid region). The highest peak in the Sahara is Emi Koussi (3,415 metres (11,204 ft)) in the Tibesti Mountains in northern Chad.

People lived on the edge of the desert thousands of years ago since the last ice age. The Sahara was then a much wetter place than it is today. Over 30,000 petroglyphs of river animals such as crocodiles survive, with half found in the Tassili n'Ajjer in southeast Algeria.Fossils of dinosaurs, including Afrovenator, Jobaria and Ouranosaurus, have also been found here. The modern Sahara, though, is not lush in vegetation, except in the Nile Valley, at a few oases, and in the northern highlands, where Mediterranean plants such as the olivetree are found to grow. The region has been this way since about 1600 BCE, after shifts in the Earth's axis increased temperatures and decreased precipitation.

The Second largest desert is the desert that covers 3.400.000 square kilometers area of Australia However, additional areas are considered to have a desert climate based on low rainfall and high temperature. The largest of the landform types covering Australia, deserts – and their arid climatic conditions – are found primarily in the western plateau and interior lowlands of the country.

The Third largest desert spread 2.600.000 square kilometers wide on the Arabian peninsula. The fourth desert was Turkestan desert, spreaded 1.900.000 square kilometers wide. The Fifth and also the last in this list is the Gobi desert, approximately 1.300.000 square kilometers wide.
