Did flowing water exist on Antarctica in the distant past?
Yes, flowing water did exist on Antarctica in the distant past. Geological evidence suggests that Antarctica experienced warmer and wetter periods in its history, particularly during the Eocene epoch (approximately 56 to 34 million years ago). During this time, parts of Antarctica were ice-free, and rivers and lakes were present, as evidenced by the discovery of fossilized plants and animals that require a warmer environment and freshwater sources. However, the vast majority of Antarctica's history has been characterized by cold temperatures and ice sheets, shaping the continent into the largely frozen landscape it is today.
