Secret of the Sahara

The video explores the formation and historical climate changes of the Sahara Desert. It explains how the Sahara's dry climate is influenced by the sun's heat at the equator, causing air to rise and lose moisture. The video also reveals hidden features beneath the desert, discovered by radar technology in 1981. It discusses how the Sahara has alternated between wet and dry climates over thousands of years due to natural climate cycles, and how future ice ages could transform it again.
