Here's why:
* Extreme Cold and Ice: Antarctica is a frozen desert. The extreme cold prevents rivers from forming and flowing. Instead of rivers, the continent has vast ice sheets and glaciers.
* Ice Flow: Water in Antarctica is primarily locked up in ice. The flow of ice is what dictates the movement of water, not rivers. This flow is determined by the shape of the land and the weight of the ice, not by the presence of a divide.
* Internal Drainage: Most of the meltwater in Antarctica drains internally, meaning it flows into the vast ice sheets and glaciers, rather than flowing outwards to the ocean like rivers.
Therefore, the concept of a Continental Divide, which defines the direction of river flow, doesn't apply to Antarctica.
