What is the driest place on Earth?
Quick Answer
One of the driest places on Earth is the McMurdo Dry Valleys in Antarctica, which have very little snow or rain. They are so dry because of cold, winds, and surrounding mountains that block moisture.
The Full Story
The McMurdo Dry Valleys are a polar desert in Antarctica and are often described as the driest nonpolar or one of the driest places on Earth. Strong katabatic winds and the Transantarctic Mountains help keep moisture away, and the extremely cold air holds little water vapor. As a result, the valleys have barren soil, exposed rock, and very limited life. They are an important scientific site because they resemble some aspects of Martian environments.
