1·Our brains are made up of a primitive inner core and a more evolved and rational outer core.

我们的大脑由原始的内核和进化程度更高、更具理性的外核组成。

2·Clearly, geophysicists who seek to explain and forecast changes in the field must understand what happens in the outer core.

显然，试图解释和预测磁场变化的地球物理学家必须了解外核发生了什么。

3·During critical situations, especially when a threat is perceived, the outer core loses control and fails to regulate the impulses and instinctual responses coming from the primitive brain.

在危急情况下，特别是在察觉到威胁时，外核会失去控制，无法调节来自原始内核的冲动和本能反应。

4·The Earth's magnetic field is generated as the molten iron of the Earth's outer core revolves around its solid inner core; when surges in the molten iron occur, magnetic tempests are created.

地球磁场是由地球外核的熔铁围绕固体内核旋转而产生的；当铁水激增，就会发生磁暴。

5·The core of the earth is made up of a liquid outer corea solid inner core.

地核是由一个液体的外核和一个固体的内核组成的。

6·The Earth's magnetic field is generated by currents flowing in Earth's outer core.

地球磁场由地球外核中的电流产生。

7·It turned out that whatever the outer core is made of, it isn't an iron-oxygen mix.

出现的结果是无论外核是什么造就的，但它不是铁和氧的混合。

8·The outer core of the Earth, about two-thirds of the way to the center, is molten iron.

地球的地核外部，大致到达中心三分之二的地方是熔化的铁。

9·They also suspect a fluid outer core generates the planet's magnetic field though convection.

他们还怀疑流体外核产生的磁场领域通过对流。

10·The great bulk of the liquid outer core of the planet, of course, is made of molten iron.

这个星球的大块的液体外核，当然，由融化的铁构成。
