Answer 2

Answer:

The shift from a lush green plain to the world's hottest desert came as a result of wobbling in the tilt of the Earth's orbital axis which in turn changes the angle at which solar radiation penetrates the atmosphere resulting to an increase in solar radiation in Earth's Northern Hemisphere during summer months.

The Sahara region has been subject to seasons of humidity and aridity. The fluctuations of these seasons as a result of Earth's tilt made Sahara region to be the world's hottest desert.
