Why is the Antarctic circumpolar current able to flow all the way around Antarctica without bending north or south?

The Antarctic Circumpolar Current (ACC) flows uninterrupted around Antarctica primarily due to the unique geography of the continent, which is surrounded by the Southern Ocean. This vast, deep ocean basin allows the current to move freely without significant landmass interference. Additionally, the strong westerly winds and the Coriolis effect help maintain its circular path, preventing the current from bending north or south. This combination of factors creates a continuous, powerful flow that encircles the continent.
