The Earth is the planet we live on and the only planet with life on it.
The layers are Atmosphere,Crust,mantle,Outer Core and Inner Core are it’s layers.
The first layer is the Atmosphere this may be known as the sky.
This layer is mostly made up of air,clouds and oxygen.
Fun fact Earth's Atmosphere used to be poisonous.
The second layer is sometimes called the ground, it is the Crust.
It is mostly made up of rock,grass,dirt and sand and it is the only thing that protects us from the hot mantle*It’s 40 kilometers deep.
(* see below for more on the mantle. )
The third layer is the mantle which is pretty hot so don't bother with sun block.
It’s made of rock that behaves like liquid. The mantle is 2,900 kilometers thick
and is thought to be 4.5 billion years old the mantle is the thickest layer of the Earth.
The outer core is the fourth layer.
It’s only 1.3 billion years old.
Inge Lehmann found the outer core.
The outer core is the only liquid layer.
It is the size of the moon and It's Hot Really Hot.
It Creates a Magnetic Field and Spins Faster Than the Surface of the Earth.
It's Mostly Made of Iron.
