解析 B 正确答案:B解析:本题考查考生的理解能力,根据原文内容“During a reversal,the main field weakens, almost vanish-es,and reappears with opposite polarity.”在反向运转时,主要的磁场就会减弱,几乎彻底消失,甚至重新出现相反的磁极。根据这句话可以知道,地球磁场开始向它的反方向改变,所以B比较符合题意。
Preface The observation of the Earth's magnetic field is destined to play a crucial role in understanding the Earth system. The great potential of ground magnetic observations allows an impressive coverage of a diverse range of topics in the modern "magnetic world", in particular (i) development...
