Where is the dryest place on earth?

The dryest place on Earth is the Atacama Desert in Chile. It is located in the rain shadow of the Andes Mountains, which block moisture from reaching the area. The average annual rainfall in the Atacama Desert is less than 1 millimeter (0.04 inches). Some parts of the desert have never seen rain. The Atacama Desert is also one of the hottest places on Earth, with temperatures often reaching over 40 degrees Celsius (104 degrees Fahrenheit).
