我们知道，地球上增温最强的地方是阳光几乎垂直投射的地方，即在南北两条回归线之间的地区。自此向南北两极，阳光愈来愈倾斜。在两极附近，阳光几乎沿切线射入，那里没有增温，阳光只是照耀地面。所以，南北极是极为寒冷的地方。那么，是北极冷还是南极冷呢？北极，是四周被 We know that the most warming place on Earth is where the sunlight is projected almost vertically, that is, in the area between the two regression lines between the north and the south. Since then, the north and south poles have become more and more inclined. Near the poles, the sunlight is almost tangentially injected, where there is no warming, and the sun only shines on the ground. Therefore, the north and south poles are extremely cold places. So, is the Arctic cold or the Antarctic cold? The Arctic is surrounded by
