Is Antarctica the driest place on earth?

Antarctica is indeed extremely dry, but it is not the driest place on earth. The driest place on earth is the McMurdo Dry Valleys in Antarctica, which receives an average of less than 10 millimeters (0.4 inches) of precipitation per year. However, the Atacama Desert in Chile holds the record for the driest non-polar desert, receiving an average of only 1 millimeter (0.04 inches) of precipitation per year.
