$\: \: \: \huge\color {pink}\boxed{\colorbox{black} {✯Answer}}$

The core of the Earth is like a ball of very hot metals. The outer core is so hot that the metals in it are all in the liquid state. The outer core is located about 1800 milesbeneath the crust and is about 1400 miles thick. The outer core is composed of the melted metals nickel and iron.

Answer 2

Answer:

The inner core, the outer core, mantle and crust are the four layers of earth.

Explanation:

◇ The Inner Core

It is the centre and the hottest layer of the Earth. The inner core is solid and made up of iron and nickel with temperature up to 5,500oC. Due to its immense heat energy, the inner core is more like the engine room of the Earth.

◇ The Outer Core

The outer core of the Earth is similar to a very hot ball of metals, whose temperature is around 4000 oF to 90000F. It is so hot that the metals inside are all in the liquid state. The outer core is located around 1800 miles under the crust and approximately 1400 miles thick. It is composed of metals such as iron and nickel. The outer core surrounds the inner core.

◇ Mantle

Mantle is the widest section of the Earth. Its thickness is approximately 2,900 km. The mantle is mainly made up of semi-molten rock known as magma. The rock is hard in the upper part of the mantle, but lower down the rock is softer and begins to melt.

◇ Crust

The crust is the outer layer where we live. The thickness is around 0-60 km. It’s a solid rock layer divided into two types:

•Continental crust covers the land and,

Continental crust covers the land and,•Oceanic crust covers water

The crust is the most widely studied and understood. Mantle is hotter and capable of flowing. The outer and inner core are much hotter with great pressures that you can be squeezed into a ball smaller than a marble if you are able to go in the center of the Earth.
