Explanation: The Atacama Desert is a desert plateau situated in South America, west of the Andes Mountains. It spreads across 600-miles on the Pacific coast and is known to be one of the driest places in the world as it receives less precipitation in comparison to the polar deserts. This desert is mostly composed of salares (salt lakes), stony terrain, sand, and felsic lava which flows towards the Andes. All of these factors together make this desert the most difficult-to-develop region in Chile.
