Please mark it as a brilliant answer..
Answer:
there are four types of layers of earth....
1) 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 upto 5,5000 C. Due to its immense heat energy the inner core is more like the engine room of the earth.
2) Outer core : The outer core of the Earth is similar to a very hot ball of metals whose temperature is around 40000 F to 90000 F. It
is it 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.
The Inner core has pressures and temperatures so high that metals are stress together and not able to move like a liquid but are forced to vibrate instead of solid.
3) Mantle : Mantle is the widest section of the earth. it's thickness is a approximately 2900 kilometre. Mantle is mainly made up of semi molten Rock known as magma. the rock is hard in the upper part of the mental but lower down the rock is softer and begins to melt.
the mental is located directly under the Sima . The mental consists of very hot and dense rock.
4) Crust : The crust is the outer layer where we live. the thickness is around 0 to 60 km. it's a solid Rock layer divided into two types :
1. Continental crust covers the land and,
2. 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 water with grid precious that you can squeezed into bol smaller than a marble if you are able to go in the centre of the earth.
