The landforms in this desert undergo constant change. These landforms are shaped as per the direction of the wind and the occasional rainfall.
In spite of being a desert, one can notice annual rainfall in many regions of this vast land. There are different climates witnessed in different regions, such as the subtropical climate in the northern part, and a tropical climate in the southern part. Over the years, the climate of the Sahara has undergone many changes.
On an average, the yearly rainfall in the Sahara is less than 3 inches. Also, there is no consistency or trend that can be seen. Meaning, it may rain more than once over a span of a few days, or might not rain even for a couple of years at a stretch.
The Sahara has annual temperatures that can exceed 86°F. Some of the hottest months have temperatures exceeding 122°F. In the winters, temperatures drop below freezing point.
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.
This desert has some of the tallest sand dunes, and these can reach around 190 meters in height. The land area also has stone plateaus, large gravel plains, dry valleys, and even sand flats.
Thousands of years ago, this area was actually a fertile land, where animals like elephants and giraffes were seen grazing around. Around 6,000 years back, the climate started becoming drier, and has become what we see today.
Emi Koussi is the highest peak that is seen in the Tibesti Mountains. This peak has a height of 3,415 m.
Farming is being practiced in certain areas of the Sahara desert with the help of drought-resistant plants. Some areas of this land have been transformed in order to prevent soil erosion.
The most widely spoken language here is Arabic, though there are several parts that have various Berber dialects too.
This mysterious and vast place also has some of the most magnificent landscapes, and despite the harsh weather, it has attracted many people to study details associated with the Sahara desert. This desert is more than a hot and dry place, it is one of the most remarkable areas known to man!
