Did the Sahara Desert used to be an ocean?
New research describes the ancient Trans-Saharan Seaway of Africa that existed 50 to 100 million years ago in the region of the current Sahara Desert. The region now holding the Sahara Desert was once underwater, in striking contrast to the present-day arid environment.
Did the Sahara used to be green?

What is unique about the Sahara Desert?
The Sahara is the hottest desert in the world – with one of the harshest climates. The average annual temperature is 30°C, whilst the hottest temperature ever recorded was 58°C. The area receives little rainfall, in fact, half of the Sahara Desert receives less than 1 inch of rain every year.
What would happen if the Sahara desert flooded?
“Floods, landslides most of the vegetation would die.” The land isn’t covered with vegetation, so the erosion will be immense. In large parts of the Sahara the aquifer isn’t far below the surface. With 300 inches a year, you have enough water to saturate 75 FEET of sand.
