How does the interior of Earth work? 

Humans who can reach to the moon and stars and learn about them, it is important to learn about their own planet earth first. The theory of the sliding of the geographical plate “tectonic plates” helps us to understand the geographical activities.

But is it enough? The geography of our planet is more complicated than the clock of big ben. Now we must answer a lot of questions. When we look under the tectonic plates, we see that under 6300 kilometers deep there is a stone and iron type mine due to which earth’s planetary furnaces are permanent. Above this, there are crusts of tectonic plates, which are like the thorns of the clock, which provide limited information but are unable to tell what is behind those movements. Scientists used onion to understand the crust as an example... and this value was reasonable. In the depth of the earth, this is obvious from the seismic waves that on which rocky metal, tectonic plates are moving, its thickness is almost 2800 kilometers. Below that is 3470 kilometer in depth there is melted lava and exactly below is core. Now if we only focus on the mental so it is also 670 kilometers in depth is divided into upper and lower layers. Then below the lower mental there is a layer which is hundreds of kilometers below.  

Before the theory of tectonic plates, the assumptions increased about the onion. Earth, according to its activities, is divided into parts with a depth of 670 kilometers. Some evidence was found that there is a layer under the lower layer of mental with couple of kilometers which may be the last layer of the mental. 670 kilometers above, metal erupts or boils like water in a utensil. Through this process raw materials and the heat of the new rocks reach the middle of the bay.
