Pole Poll
Which is colder, the North Pole or the South Pole?
The correct answer is the South Pole. The average yearly temperature there is minus 58 degrees Fahrenheit, while at the North Pole, it's a balmy zero.
Though on opposite sides of the planet, the poles have this much in common: Both poles have six months of continuous darkness each year, and even when the sun shines, it never rises more than 23.5 degrees above the horizon and even then, all that white snow ends up reflecting most of that heat rather than absorbing it.
Polar Opposites
The difference is that the North Pole is located on a relatively thin sheet of sea ice in the middle of the Arctic Ocean, and all that water has a regulating effect on the air above it, cooling it down in the summer and warming it up in the winter. This causes the sea ice to grow and shrink depending on the season, which, in turn, affects the air temperature at the pole itself. In contrast, the South Pole is located on top of several thousand feet of thick ice, which sit on top of the continent of Antarctica, so the ice never gets a chance to melt. Plus, Antarctica is the highest continent on earth, and the South Pole is a whopping mile and a half above sea level, which also accounts for the colder temperatures.
