Why is the Atacama Desert the driest desert on Earth?
Why is the Atacama Desert so dry? The Atacama Desert is located in a zone called the “shadow of rain”. Basically, there is an absence of rains and high evaporation. These natural, complex, and dynamic factors make the Atacama Desert an incredibly dry place.

In the relatively mild Mojave Desert, nearly 100% of quartz pebbles are colonized by hypoliths. In the nearby hyperarid desert of Baja California, in contrast, only between 26 and 38% of quartz stones were colonized. This shift is in keeping with extensive studies along a moisture gradient in the Atacama Desert.
