We are happy to see you here, and we try to provide you best facts about SAHARA DESERT.
The Sahara is the largest hot desert and the third in the world after Antartica and the Artic. Its area of 9,200,000 square kilometres (3,600,000 sq mi)
is comparable to the area of china or the united states. The Sahara is the worlds largest low-latitude hot desert. So We concluded some most amazing facts about SAHARA DESERT.
Here are the 26 interesting facts about SAHARA DESERT.
The Sahara desert covers around 3,600,000 square miles, and the overall area is as large as continental United States. This desert also has the
reputation of being the world's largest hot desert.
The Sahara desert now comprises eight percent of the world's land area - one could actually place the entire continental United States within the
Sahara Desert and still have a few thousand square miles of desert left over.
The Sahara Desert is the world’s largest hot desert. But of all the deserts in the world, it ranks 3(third) in terms of area. It comes after
Antarctica and Arctic deserts. The Antarctica and Arctic deserts are cold deserts.
This desert has some of the tallest sand dunes, and these can reach around 190 meters in height.
Goats and camels are the most common domesticated animals in the Sahara.
The people who live in the Sahara are mostly nomads. Nomads move from place to place.
Sahara means ‘the greatest desert' in Arabia.
The desert shrinks and grows depending on the climate.
Did you know that Sahara consists of 70% gravel and 30% sand.
The highest point in the Sahara Desert is Emi Koussi. This is a shield volcano in northern Chad.
Potential evaporation is extremely high. It ranges from 2,500 millimeters to 6,000 millimeters per year.
Major cities in the Sahara Desert are Nouakchott, Tamanrasset, Ghardaia, El Oued, Ghat etc.
One half of the Sahara Desert receives less than 79 inches of rain each year. The rest of the desert only receives 3.9 inches per year.
There are several languages spoken in the Sahara. However, Arabic dialects are the most widely spoken ones.
The landforms in this desert undergo constant change. These landforms are shaped as per the direction of the wind and the occasional rainfall.
The Sahara Desert is made up of sand dunes, sand seas, gravel plains, stone plateaus, dry valleys, salt flats, mountains, rivers, streams, and oasis.
Here are many divisions of the Sahara Desert. They are Western Sahara, Libyan Desert, Aïr Mountains, Tibesti Mountains, and Ahaggar Mountains.
The Sahara was not always this big, poorly populated sandbox. As recently as 6,000 BC, grains and millet were grown across much of what is now the Sahara.
Intertropical Convergence Zone is the major source of rain for this desert. This zone brings irregular rains to Southern Sahara and Sahel regions.
31% of the total area of Sahara Desert(1,100,000 square miles or 2,800,000 square kilometers) receives nearly 10 millimeters of rainfall.
At around 500 BCE, Greeks traders started trading along the desert’s eastern coast. Many urban civilizations like Garamantes rose around the
same time and that too at the very heart of Sahara.
The Sahara desert stretches over areas of Northern Africa, from the Red Sea to the areas close to the outskirts of the Atlantic Ocean. It
shares its boundaries with the Atlas Mountains, the Mediterranean Sea, Egypt, Sudan, and valley of the Niger River.
During the nights, temperatures usually fall anywhere between 13 to 20 degrees Celsius. Coastal areas are colder than inland areas. During
winters, the temperature can go below 0 degrees Celsius at night.
Ground and sand temperatures are even higher. During the day, the temperature of the sand is nearly 80 degrees Celsius and ground temperature
is nearly 72 degrees Celsius. The average temperature of the desert is nearly 25 to 30 degrees Celsius.
It is said that the changes in the orbit of the earth cause changes in the insolation (incoming solar radiation), which in turn controls the
monsoon patterns all over the world. This theory was first proposed by Rudolf Spitaler in the 1800s.
The Sahara that we see today is the dry or “desert Sahara” (because of weak North African Monsoon). In 15,000 years from now, there will be
“green Sahara” (because of strong North African Monsoon).
