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 innercore drives complex fluid dynamics through convection in the planet's molten outer core, causing an electrical charge which generates a global magnetic field.
