North Pole and South Pole (extra)

In general, temperatures at the South Pole average 54℃ lower than the North Pole. So why is the southern tip of the Earth so much colder than the northern tip? Th answer lies in the geography of each location. While the North Pole is, by definition, located at sea level – there is no solid land at the North Pole, only a series of icy formations in winther – the South Pole sits 2,730 meters above sea level. Higher elevations are colder that locations at low altitudes, because seawater acts as an insulator, holding in heat from the sun and warming the air around it. Because the North Pole is nothing but seawater, it is able to retain heat more efficiently than the high and dry South Pole.
