Which layer is the hottest layer of earth?

Hereof, which layer of the Earth is the hardest?

Out of them, the mantle is the thickestlayer,while the crust is the thinnest layer. TheEarth canbe divided into four main layers: the solidcrust on theoutside, the mantle, the outer core and the inner core.Out ofthem, the mantle is the thickest layer, while thecrust isthe thinnest layer.

Similarly, why is the inner core the hottest layer? The inner core is solid because it is made ofverydense, or heavy, materials - like iron and nickel. Even thoughit isvery hot, these materials don't "melt" very easily, sotheystay solid. Answer 3: It turns out that many materials can beasolid at a higher temperature if the pressure isalsohigher.

Also know, what is the correct order of the Earth's layers?

The different parts of the Earth are thecrust,mantle, outer core, and inner core.

Which layer of Earth is the heaviest?

It is the largest layer of the Earth,1800miles thick. The mantle is composed of very hot, dense rock.Thislayer of rock even flows like asphalt under a heavyweight.This flow is due to great temperature differences from thebottomto the top of the mantle.
