Antarctica - Ice, Wildlife, Continent: The geologic evolution of Antarctica has followed a course similar to that of the other southern continents. The earliest chapters in Antarctica’s rather fragmentary record extend far back, perhaps as much as 3 bil
Despite all its ice, Antarctica is classified as a desert because so little moisture falls from the sky. The inner regions of the continent receive an average of 2 inches (50 millimeters) of precipitation — primarily in the form of snow — each year. To put that into perspective, much of...
