Space center experts were worried earlier in the day when Xichang experienced an unexpected rainfall from about 4:05 a.m.till 7:10 a.m.on Wednesday, but they were able to breathe a sigh of relief when the weather cleared.南北极地区有很多问题迷惑着小明和小华,下面是两人在几个问题上的观点及其理由,请你对他们的观点进行评价,并说明你的理由。问题一:关于南极、北极哪个更冷?小明的观点:北极更冷,因为北冰洋处于高纬地区,一年之中受到的太阳光热最少。小华的观点:南极更冷,因为南极地区一年中受到的太阳光热最少,南极地势高,冰层巨厚,气温更低,是世界寒极。问题二:关于南极地区有丰富煤炭资源的猜想。小明的观点:南极洲原先并不在现在的位置,而是从温带或热带地区飘移过来的,那时,这片大陆上有大片的森林,后来形成了煤层。小华的观点:南极洲的位置并没有变化,只是原先的气温并不是这样低,曾有茂密的森林,形成煤层,只是后来不明原因,气温降到现在的情况。问题三:关于南极最佳的考察时间。小明的观点:盛夏7月,气温最高,最适宜在南极考察。小华的观点:每年2月份左右,是南极的暖季,最适宜考察。评析:____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
