The Earth is made up of three layers, the crust, mantle and core.
The crust is the solid outermost layer. It is separated into pieces called plates. Rocks are solid materials that are made up of minerals and they are on the Earth's crust. The crust floats on the Earth's mantle. The mantle is liquid and is more than 200 degrees celcuis. And right in the center of the Earth, there is the core, which is solid. The core is 5150-6370 kilometers below the Earth's surface and mainly consists of iron, nickel and some lighter elements. The core's temperature is about 5000-6000 degrees celcuis.

The core is made up mainly of iron, nickel and some other lighter elements right? Since Iron and Nickel are metals, how are they able to withstand such intense heat? And what are the other lighter elements? These are Just some thoughts that ran through my mind as I was reading this post.
