Interesting Facts about the Sahara Desert
The Sahara desert covers around 3,500,000 square miles, and the overall area is as large as the continental United States. This desert also has the reputation of being the world's largest hot desert.
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. The landforms in this desert undergo constant change. These landforms are shaped as per the direction of the wind and the occasional rainfalls.
In spite of being a desert area, one can notice annual rainfall in many regions of this vast land area. There are different climates witnessed in different regions, such as the subtropical climate in the northern part, whereas a tropical climate in the southern area. Over the years, the climate of the Sahara desert has undergone many changes. This desert therefore, is known for its harsh climates.
On an average, the yearly rainfall here is even 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. This hot desert has annual temperatures that can exceed 86 degrees Fahrenheit. Some of the hottest months have temperatures exceeding 122 degrees Fahrenheit. In the winters, the temperatures drop below freezing point. This itself explains the diverse climates of this hot desert.
