Have you ever wondered what the inside of the earth looks like or what it might feel like? Here you will be given information that can help you create a picture of the inside of the earth, INSIDE YOUR HEAD!
The earth is made up of 4 layers
The Crust
The Mantle
The Outer Core
The Inner Core

The Crust
The Crust is the Earth's first layer lying right beneath your feet. It varies in depth from about 5 kilometers under the ocean and 60 kilometers under continents. To get a better picture in your head, The crust only takes up 1% of the Earth.
The crust is made up of basalt and granite-like rocks.
The temperatures in the crust change depending on where you are.
The temperatures vary from 200 °C to 400 °C

The Mantle
The mantle is the second layer of the Earth and the largest,
it takes up 81% of the Earth.
The Mantle is approximately 2900 km thickIt is made of silicates of iron and magnesium, sulfides
and oxides of silicone.
The Mantle is 3000° C
Parts
It has two sections the Asthenosphere and the lithosphere.
The Athenosphere is closest to the inner and outer core. The lithosphere is closest to the crust of the Earth.
Convection Currents
A Convection Current is when the hot
substances of the Athenesphere rise. When they
reach the lithosphere, they cool because they are further away from the heat source (the inner core). They then become more dense. The density causes it to be heavier. It then begins to go back down into the Asthenosphere
and this cycle is repeated over and over again. That's what causes continental drift.

The Outer Core
The outer core surrounds the inner core.
The outer core is made of Iron and nickel liquid.
Secondary-waves can not pass through the outer core.
The outer cores temperature is about 4000 to 5000 °C.
The outer core is about 2,890 and 5,150 km below the Earth and about 220 km thick.
The outer core is made of Iron and nickel liquid.
Secondary-waves can not pass through the outer core.
The outer cores temperature is about 4000 to 5000 °C.
The outer core is about 2,890 and 5,150 km below the Earth and about 220 km thick.
The Inner Core
The Inner Core is the very center of the earth it is also the hottest part of the planet. The Inner Core is hotter than the sun.
It is approximately 5000 to 6000 °C.
It is made of mostly iron and nickel.
The Inner Core is solid because of all the pressure.
The Inner core is about 60 km from the crust.
It is approximately 5000 to 6000 °C.

The Inner Core is solid because of all the pressure.
The Inner core is about 60 km from the crust.
