Despite its highly variable climate, the Sahara Desert is home to over 100 species of reptiles, 70 mammals, and 90 species of birds.
The Sahara Desert covers an area of about 8.600.000 square kilometers in North Africa, making it the largest hot desert in the world. This region includes parts of Libya, Niger, Sudan, Algeria, Mali, Morocco, Chad, Egypt, Mauritania, and Tunisia.
During the day, temperatures in the Sahara rise to very high levels and drop again at night. The arid landscape includes impressive dunes, sand seas, rocky plateaus and green oases.
Despite these difficult living conditions, the Sahara Desert is not a lifeless place.
Has the Sahara always been a desert?
Scientists believe that the area now known as the Sahara Desert was covered by the vast Tethys Sea millions of years ago. The shrinking of this sea led to the formation of the desert and left behind the Black Sea, the Mediterranean Sea, and the Caspian Sea.
According to experts, the loss of this large body of water led to a gradual decrease in rainfall in the region. However, around 6 years ago, the Sahara was not so dry, as there was still enough rainfall to support vegetation.
Fossils discovered in the Sahara tell the story of a land once filled with amazing creatures, including a 10-meter-long dinosaur fossil believed to be millions of years old.
Researchers have also identified remains of marine animals in this region, including catfish and tilapia, providing a glimpse into what this area may have once been like, writes The Fact Site.
How do people survive in the Sahara Desert?
Temperatures in the Sahara can reach extremely high levels during the day, up to 50 degrees Celsius. However, at night, the temperature can drop significantly, sometimes even below freezing during the winter months, such as January or February.
These extreme temperature fluctuations make the Sahara a challenging environment for human livelihood and survival.
The few people who live around certain areas of the Sahara wear loose clothing to cope with the heat. This helps slow the evaporation of sweat and reduces water loss. They also wear face and head coverings, which protect them from the dusty desert winds.
Harsh temperatures and winds aren't the only reason the Sahara isn't an easy place to live. The region receives very little rainfall each year. That's why many communities are located around oases, and nomadic tribes move seasonally from one region to another.
What animals and plants can be found in the Sahara Desert?
Despite the hardships of living in the Sahara, a variety of plants and animals have adapted to these conditions. The plants found here can survive the heat and drought.
One of the most popular plants in the Sahara is the date palm, which grows up to 23 meters tall. The candy-flavored dates it produces are an essential part of the diet of the inhabitants there. Other common plants include the olive, Saharan cypress, doum palm, tamarisk, and desert gourd.
Many people associate the Sahara with camels, and rightly so. But the Sahara is home to more animal species than you might imagine, including over 100 reptiles, 70 mammals, and 90 bird species.
Some interesting animals in this region are the scorpion, the desert crocodile, the African bushbuck, and the African wild dog. Unfortunately, some populations of desert animals and plants are facing the risk of extinction.
The Sahara Desert has not always been dry. This area was once under a vast sea and supported a rich flora and fauna. Despite its harsh living conditions, millions of people call the Sahara home.
They have adapted their clothing and lifestyle to suit this unique environment. The plants and animals of this region have also evolved to survive.
