The Earth is composed of three main layers: the crust, the mantle and the core. A) Inner core, B) Outer core, C) Mesosphere, D) Lithosphere, E) Astenosphere, F) Oceanic crust, G) Continental crust, H) Litosphere, I) Outer mantle, J) Astenosphere.

What are the layers of the Earth?

Three main layers compose the Earth.

  • The crust

This is the most external layer.

It is located right upon the mantle and is divided into many plates, that move over it.

It is composed of the oceanic basaltic plate (6-12 km) and the uppermost continental granitic plate (25-70 km).

  • The mantle

This is the second layer that composes the Earth.

It is a very hot and dense rock that is capable of flowing.

Convection currents occur in this layer, rising hot melted material from the deepest region and sinking cold solid material from the surface.

Three layers compose the mantle,

Upper mantle (40-400km)

Transition zone (400-670km)

Inner mantle (2285 km)

  • The core

This is the third layer and is divided into two sublayers,

- the solid inner core (1216 km)

- the liquid outer core (2270 km)

The core is mainly composed of Ferrum and nickel, and its temperature is about 6000ºC.

The extremely high temperatures are closely involved in material circulation, keeping the Earth's surface temperature, and  electromagnetic field.  

• The core composes the Endosphere

• The Internal mantle composes the Mesosphere

• The Transition zone and superior mantle compose the Astenosphere

• The Crust composes the Lithosphere

In the attaches filed you will find the correct names of each layer.

A) Inner core

B) Outer core

C) Mesosphere

D) Lithosphere

E) Astenosphere

F) Oceanic crust

G) Continental crust

H) Litosphere

I) Outer mantle

J) Astenosphere
