答案

答案:A

题目分析:2004年,中国在北极建立的第一个考察站是黄河站。

点评:本题还可以考查北极地区位于北纬66.50(北极圈)以北,是位于地球最北端的地区,它包括北冰洋的大部分以及沿岸的亚、欧、北美三洲的陆地和岛屿,跨东西两半球,北冰洋是世界上纬度最高、跨经度最广的大洋。南极地区位于南纬66.50(南极圈)以南,是位于地球最南端的地区,它包括南极大陆以及周围的海洋,跨东西两半球,南极洲是世界上纬度最高,跨经度最广的大洲。南极地区逆时针环绕着太平洋、大洋洲、印度洋、非洲、大西洋和南美洲。气候:1.南极地区的自然环境特征主要表现在酷寒(纬度高、大风吹散热量、海拔高、冰面反射太阳光)、烈风(阻挡较小、气压差大)、干旱三个方面,因此有“冰雪高原”、“白色沙漠”、“风库”等称号。北极地区由于绝大部分为大洋,气温不像南极那么寒冷,降水量比南极地区多,风速也比南极地区小。北极地区的代表动物为北极熊,南极地区的代表动物为企鹅。科学考察的宝地;我国于1983年正式加入《南极条约》,为保护南极、维护和平做出了巨大贡献。
