众所周知,地核分为内核和外核两个部分,熔融的液态铁和液态镍将内地核层层包裹,形成了所谓的外地核,液态金属的周期性流动产生了电流和地球磁场。然而最新的研究显示,由于外地核的运动正发生着巨大的变化,这导致了地球表面一些地区磁场强度的减弱。“这一变化将是灾难性的!”丹 As we all know, the earth core is divided into two parts: the inner core and the outer core. The molten liquid iron and liquid nickel wrap the inner nuclear layer to form the so-called foreign core. The periodic flow of liquid metal produces the electric current and the earth’s magnetic field. However, the latest research shows that due to the tremendous changes taking place in the movement of the nuclear in the outer field, this has led to a decrease in the magnetic field intensity in some areas of the Earth’s surface. “This change will be catastrophic!” Dan
