人们常用南北极磁场来辨别方向,这在地球演变历史中并不完全管用。科学家们在对黄土高原古地磁研究中证实,地球在其生长过程中确实发生过多次南北磁极倒转、南北磁极漂移的事件。
People often use the magnetic field to identify the direction of the North Pole, which in the evolution of the Earth’s history is not fully functional. Scientists in the paleomagnetic study of the Loess Plateau confirmed that the Earth did occur in its growth process many times north-south pole reversal, north-south pole drift event.
