Layers of the Earth

The erth Tis made up iof three sections which are divided into eight layers. Each layer gets more dense as you get closer to the middle of the Earth

The first section is called the Crust. It's 1.4% of the earth's volume. The two layers are the Continental Crust and the Oceanic Crust. The Continental Crust is the surface where we walk and play. The Oceanic Crust is right under the surface, and humans have yet to drill past it into the Mantle.

The Mantle is the next section of Earth. It is 84% of earths volume, and has the most layers out of the three. The four layers are called the Lithosphere, the Asthenosphere, the Upper Mantle, and the Lower Mantle. The Lithosphere is called that because that layer is full of rocks. Litho means rock; it's from the Greek word lithos. The Asthenosphere is the second layer to the top in the Mantle. It has currents that allow the tectonic plates to move. The third layer is called the Upper Mantle. It's viscous, meaning it has a thick, sticky consistency a lot like lava. The fourth and final layer is the Lower Mantle. It's 55% of Earth's volume.

The last section is the Core. This section is 14.6% of the Earth's volume and has only two layers, the Outer Core and the Inner Core. The Outer Core is the only completely liquid layer consisting of metals, making the Earth's magnetic field. The Inner Core is the last layer and is a solid iron and nickel ball because of the extremely high temperatures and pressure. This layer is as hot as the surface of the sun.

This is a picture I colored. I got most of my information from this but used a little help from the internet, like fact checking. The picture is not to scale.
