The continent with the fewest rivers is Antarctica. Most of its landmass is covered by glaciers, and while it does have some subglacial lakes, there are very few rivers in the conventional sense found on other continents. The harsh climate and extreme conditions limit the flow of water on the surface, resulting in a landscape mostly dominated by ice. As a result, while there are some ephemeral or seasonal streams during the brief summer months, the overall river system is minimal compared to other continents like Africa or North America, where extensive river networks exist.
