Understanding the Structure of the Earth

地球的最外部是地壳、地壳下面还有地幔、外地核和内地核。地球的内核是地球最热的一部分，它和太阳表面一样热哦。

The outermost part of the Earth is the crust, and below it there are earth mantle, outside earth core and inland Core. 

The inner core is the hottest part of the Earth, which is equally hot as the surface of the sun.
