Is it Sahara or Sahara Desert? The correct term is simply Sahara, as it already means "desert" in Arabic. Therefore, saying "Sahara Desert" is redundant. However, both terms are commonly used, especially in English, to refer to the vast desert region in North Africa.
What Is the Sahara?
The Sahara is the largest hot desert in the world, covering approximately 9.2 million square kilometers (3.6 million square miles). It stretches across North Africa, spanning 11 countries, including Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Sudan, Tunisia, and Western Sahara. This immense desert is known for its harsh climate, with temperatures that can reach up to 50°C (122°F) during the day and plummet to near freezing at night.
Why Is the Sahara So Vast?
The Sahara’s vastness is largely due to its geographical location and climatic conditions. It is situated in a high-pressure belt where dry, descending air inhibits cloud formation, leading to minimal precipitation. Historically, the Sahara has undergone significant climatic changes, fluctuating between dry and humid periods over thousands of years. These changes have contributed to its current expanse and arid conditions.
What Are the Key Features of the Sahara?
The Sahara is not just an endless sea of sand dunes; it features a diverse landscape that includes:
- Sand dunes (ergs): Covering about 20% of the desert.
- Rocky plateaus (hamadas): Vast barren areas of rock and gravel.
- Mountain ranges: Such as the Ahaggar and Tibesti Mountains.
- Oases: Fertile areas with water sources, supporting vegetation and wildlife.
- Salt flats: Known as chotts or sebkhas, these are depressions filled with salt deposits.
How Does Life Thrive in the Sahara?
Despite its harsh environment, the Sahara supports a variety of life forms. Adaptations are key to survival here. Plants like the date palm and acacia have deep root systems to access groundwater. Animals such as the fennec fox and the dromedary camel have evolved to withstand extreme temperatures and scarce water supply. Human populations, including the Berbers and Tuaregs, have also adapted, living a nomadic lifestyle centered around oases and trade routes.
What Is the Climate of the Sahara Like?
The Sahara’s climate is characterized by:
- Extreme temperatures: Daytime highs can exceed 50°C (122°F), while nighttime lows can drop to near freezing.
- Low precipitation: Most areas receive less than 25 mm (1 inch) of rain per year.
- Frequent dust storms: Known as "haboobs," these can reduce visibility and affect air quality.
How Do People Survive in the Sahara?
Survival in the Sahara requires resourcefulness and adaptation. Indigenous people have developed strategies such as:
- Nomadic herding: Moving livestock to find grazing areas.
- Trade: Using camels to transport goods across trade routes.
- Oasis farming: Cultivating crops like dates and barley in fertile areas.

Why Is the Sahara Called a Desert?
The Sahara is called a desert because it meets the criteria of having an extremely arid climate with very low precipitation and sparse vegetation. The term "Sahara" itself means "desert" in Arabic, emphasizing its dry and barren nature.
What Animals Live in the Sahara?
The Sahara is home to various species adapted to extreme conditions. These include the addax antelope, dromedary camel, fennec fox, and several species of lizards and snakes. These animals have evolved to conserve water and regulate their body temperature effectively.
How Old Is the Sahara Desert?
The Sahara is believed to be about 2.5 million years old. However, its current arid state has fluctuated over time due to climatic changes. The desert has experienced periods of increased rainfall, known as "Green Sahara" phases, which supported more lush vegetation and diverse wildlife.
What Is the Largest City in the Sahara?
The largest city in the Sahara is Nouakchott, the capital of Mauritania. It serves as a major economic and cultural center in the region, despite the challenging desert environment.
