Really cold, or
really, really cold?
Both the Arctic (North Pole) and the Antarctic (South Pole) are cold
because they don’t get any direct sunlight. The Sun is always low on the
horizon, even in the middle of summer. In winter, the Sun is so far below the
horizon that it doesn’t come up at all for months at a time. So the days are
just like the nights—cold and dark.
The North Pole and South Pole are “polar opposites,” they both
get the same amount of sunlight. But the South Pole is a lot colder than the
North Pole. Why? Well, the Poles are polar opposites in other ways too.
The Arctic is ocean surrounded by land. The Antarctic is land surrounded by
ocean.The ocean under the Arctic ice is cold, but still warmer than the ice! So the ocean warms the air a bit.
Antarctica is dry—and high. Under the ice and snow is land, not ocean. And
it’s got mountains. The average elevation of Antarctica is 2.3 km. And the
higher you go, the colder it gets.
