Hi. My name is Jo. I am 15 years old and I am in 9th grade. I love science. It is one of my favorite subjects in school. I have always been amazed by the Earth's layers so I decided I am going to explain to you what we would see if we journeyed to the center of the Earth!
In order to make it to the center of the Earth, there are 5 layers that you would encounter and would have to get through. Those include the Lithosphere, Asthenosphere, Mesosphere, Outer Core, and Inner Core.
The first layer of the Earth that you would have to go through is the Lithosphere. The Lithosphere is the rigid, outermost layer of the Earth. It consists of the crust and the upper mantle.
The Lithosphere is made up of rocks. It is the least dense layer of the Earth. The Lithosphere is divided up into pieces called tectonic plates.
The next layer you would have to go through is the Asthenosphere. The Asthenosphere is in the middle of the mantle and is made up of solid rock that flows very slowly. It is a plastic layer on which pieces of the Lithosphere move.
Next is the Mesosphere. The Mesosphere is the strong lower part of the mantle. It is located below the Asthenosphere. The Mesosphere is the largest, and thickest layer of the Earth.
