How the Earth Was Made
Driest Place on EarthDVD - 2008
The Atacama desert is considered the driest place on Earth. Since human records of the area began, some places have never received rain. But the records don't stop there, the Atacama is also the oldest desert in the world, dating to an amazing 150 million years old. Other research shows that it's surface is also incredibly ancient - there are boulders lying in this desert that have not moved for over 23 million years - that's over 50 times longer than it's taken for our human species to evolve. The soil is so dry that it has been used as a test bed for the Mars rovers. Once thought completely lifeless, strange bacteria discovered in the desert have given scientists new hope that they might find life on the red planet. Atacama is also home to the largest copper mine in the world. How the Earth was made looks into the riddle of the Atacama and uncovers how this extraordinarily dry landscape was created.
