Why Antarctica Is Colder Than the Arctic

Antarctica is generally colder due to:

1. Landmass vs. Ocean: Antarctica is a continent with thick ice sheets; the Arctic is an ocean surrounded by land. Land absorbs/releases heat differently, and ice sheets enhance cooling.
2. Oceanic Influence: Warm currents moderate Arctic temperatures; Antarctica is isolated by the Southern Ocean with minimal warm water intrusion.
3. Land-Sea Distribution: Northern continents warm the Arctic via landmass heat; Antarctica lacks this.
4. Atmospheric Circulation: A stable, strong polar vortex over Antarctica traps extreme cold for long periods.

Both poles are frigid, but these factors make Antarctica colder on average.
