How is the North Pole different from the South Pole?

When you look at the Earth from space, you can see that the North and South have completely different terrain. Antarctica is a vast land mass with an area of about 12.61 million square kilometers, called Antarctica; The North Pole is a vast ocean, covering an area of about 14.09 million square kilometers, called the Arctic Ocean. From the data we can see that they are very similar in size.

At 1,200 meters deep, the Arctic sea is the shallowest sea in the world; In contrast, the elevation of the Antarctic continent averages about 1,500 meters.

The Antarctic continent is almost entirely covered by large continental glaciers, and the average thickness of the ice is about 1,700 meters, and the thickest places are up to 2,800 meters. The ice here accounts for about 90% of the world's total, about 10 to 8 times the amount of sea ice in the Arctic, if all the ice in Antarctica melted into the sea, it would raise the global sea level by 60 to 80 meters.

There are two kinds of ice at the poles: sea ice and icebergs, which form in different environments. Sea ice freezes directly in the ocean, so when it melts, it is salt water; Icebergs, on the other hand, are formed when large chunks of ice from nearby glaciers fall into the sea, so they are fresh water when they melt.

The northern and southern skies often appear in the aurora, occurring in the ionosphere of the atmosphere, is the result of the solar wind blowing to the Earth, very beautiful.

The animals of the North and South are also different: the polar bear with fur in the North; There are penguins in Antarctica.
