Therefore, we have defined CIP axis of fluid core Earth and resolved it.

由此定义液核地球的CIP轴，并对其进行解算。

Computer simulations of this impact show that both of the objects would melt in the impact and the dense core of the impactor would fall as molten rock into the liquefied iron core of Earth.

对这次撞击的计算机模拟显示，这两个物体都会在撞击中熔化，而撞击者稠密的核心会以熔融岩石的形式落入地球的液化铁芯中。

This metallic core gives Earth its characteristic magnetic field, which has played an extremely important role in the history of our planet.

这种金属核赋予地球特有的磁场，在地球的历史上发挥了极其重要的作用。

The heat that keeps the core of the earth molten is primarily radioactive decay -it is what makes rock into liquid lava.

The research could help test simulations of how the outer, fluid core generates the Earth's magnetic field, which shields our planet and the teeming life on it from harmful cosmic rays.

The inner core, made of very pure, solid iron, rotates along with the outer core, dragging the Earth's magnetic field with them.
