earth inner core

The formation of Earth's crust protected the inner layers of Earth from the high-energy particles in space, reducing the temperatures of the mantle and the core.

地壳的形成保护了地球的内层不受太空中高能粒子的影响，降低了地幔和地核的温度。

On Earth, heat from the solid inner core drives complex fluid dynamics through convection in the planet's molten outer core, causing an electrical charge which generates a global magnetic field.

在地球上，从坚固的内磁芯的热量通过与炽热的外磁芯核的对流而形成流体动力，引起了电荷，进而由电荷产生了全球的电磁场。

The earth has an inner core that rotates clockwise and an outer core that rotates counterclockwise.

地球有一个内在核心以顺时针方向旋转，其外层核心是以逆时针方向旋转。
