Why did the Sahara dry out?

Answer 1

Because there isn't enough rainfall.

Josiah C. Answered at 5/1/2015: Most scientists believe the Sahara dried up due to a change in the Earth's orbit, which affects solar insolation, or the amount of electromagnetic energy the Earth receives from the Sun. Or to use simpler words, insolation refers to the amount of sunlight shining down on a particular area at a certain time. It depends on factors such as the geographic location, time of day, season, landscape and local weather.
