The Journey to Promote the Immutable Records in the World No.10: Sahara- the largest desert in the World

(Vietkings)The Sahara is the world’s largest hot desert and one of the harshest environments on the planet. It is third largest desert overall after Antarctica and the Arctic, which are cold deserts.

Sahara Desert (sci-news.com)

At 3.6 million square miles (9.4 million square kilometers), the Sahara, which is Arabic for "The Great Desert," engulfs most of North Africa. The desert covers large sections of Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and Tunisia.

In the north, the Sahara reaches to the Mediterranean Sea in Egypt and portions of Libya. In Cyrenaica and the Maghreb, the Sahara experiences a more Mediterranean climate with a winter rainy season.

Major cities located in the Sahara include Cairo, Egypt; Tripoli, Libya; Nouakchott, the capital of Mauritania; Tamanrasset, Ouargla, Bechar, Hassi Messaoud, Ghardaia, and El Oued in Algeria; Timbuktu in Mali; Agadez in Niger; and Faya-Largeau in Chad.

Climate and geography of the Sahara

The Sahara’s northeasterly winds can reach hurricane level and often give rise to sandstorm and dustdevil. Half of the Sahara receives less than an inch of rain per year, and the rest receives up to 4 inches (10 centimeters) per year. The infrequent rain is usually torrential.

The highest peak in the Sahara is the volcano Emi Koussi (11,204 feet or 3,415 meters) in the Tibesti Mountains in northern Chad. The desert’s other mountains and mountain ranges include the Aïr Mountains, Hoggar (Ahaggar) Mountains, Saharan Atlas, Tibesti Mountains, Adrar des Iforas and the Red Sea hills.

Many people imagine the Sahara as dotted with sand dunes, and the desert does have its share of ergs, which are large areas of shifting sand dunes, with some of some of them reaching 590 feet (180 meters). However, most of the Sahara is characterized as rocky hamada, a type of desert landscape that has very little sand and is made up of primarily barren, hard, rocky plateaus.

With the exception of the Nile River, the Sahara’s rivers and streams are irregular or seasonal. The Nile crosses the desert from its origins in central Africa to empty into the Mediterranean.

The central part of the Sahara has extremely limited vegetation. The northern and southern reaches of the desert, along with the highlands, have areas of sparse grassland and desert shrub, with trees and taller shrubs.
