Earth Layers

The earth has four different layers as scientist believe. However, if you were to look at it from space you wouldn’t be able to notice any layers, besides the very first layer the one we live on because you can only see what is shown on the outside from pictures taken from space. Have you ever wondered what’s underneath the surface we see and what is beneath the earth’s surface? It’s mostly blue because that’s all the water from the oceans, rivers, lakes and given the fact earth has more bodies of water than land. The brown and green patches is the all of the land and among the white you may see; those are the clouds in the sky. So what are the layers of earth and how is this important? Scientist are still studying the earth as much more research could potentially uncover the unknown. The research so far has showed why they have a theory about what is believed to be the earth’s layers.

The earth is divided into layers from exterior to interior; that range in size and while each layer is made up of different materials. Scientist have the belief that each feature among the layers serves a different purposes. The outer layer is the crust, as the next layer is the mantle, then you have the outer core, and the last layer has recently known now as the inner core.

The lighter material make up the exterior of earth with the heavier material being making up more of interior layers. The crust being the very outer layer, and the part of earth we live on. It’s also the thinnest layer made up of loose rock that is far beneath the ocean and below all of the continents. I like to think of this particular layer as the crust of a pie or even a hard boiled egg because it’s thin and can be easily broken as the broken material of rocks breaks up in what scientist believe to be plate tectonics.

The mantel is the thickest layer and made up of just rocks. There is a section within the mantel that’s referred to as the asthenosphere, this is the part that allows the plates of earth to move. The outer core is an important layer because it is the composed of the magnetic field, while also creating a barrier in order to protect the earth from the sun. The inner core is dense and assumed to be completely made out of metal materials like iron. Lastly, the inner core is known to be the most unique layer. This particular layer has the highest temperature and it has been said to be even hotter than the sun.

Scientist can’t really say for sure if their theory is correct. However, the research they have conducted from many earthquakes and volcanoes throughout many decades has provided scientist and geologist with far more information because they were able to measure the movements of seismic waves that are from earthquakes. The research provided them to discover the belief that the interior of the earth has a process that they call the mantle convection. This heat process of motion is what causes the materials to be able to move within the mantle. The transportation of the hot material flows upward while cool materials flow downward.

You may not be able to see it from space that the earth it’s composed of four different layers. Earth appears to be a giant blue planet that is made up of just water, land and clouds. Seemingly as far as we can see to be one layer but we know there is far more that is to be discovered underneath the earth’s surface.
