The Structure of The Earth

The Structure of The Earth

This time we will discuss the structure of the earth. When it comes to discussing something, we need to know what it is made of. What is our world made of? Hail ring theory states that Earth, Mercury, and Venus are mainly composed of matter. For example, the body of the earth is made mainly of iron rocks, stones, metal oxides etc.

The distance from the surface of the earth to the center of the earth is about 4000 miles. This distance is called radius. Scientists have divided this radius into three parts. Crust, mantle and core.

The first layer is the crust. Like forty-five miles. Less in some places. For example, the density of the crust below the ocean is only about five kilometers. If you catch it from the top of the mountain, it is like sixty-seventy kilometers. In addition to ganai, basalt, etc., the earth is composed of soil, sand, water, etc.

The next layer of the ghost is the mantle. From the crust to the bottom, about 1800 miles thick. According to geologists, heavy rocks, iron and other metals are abundant in this layer. But none of them are in a difficult situation. The reason for this is the terrible temperature at this level. At a depth of only one and a half miles, the Earth temperature has been observed to be 100 degrees Celsius, at a depth of 30 miles it has reached 1500 degrees Celsius, and at a depth of 50 miles it has exceeded 2000 degrees Celsius. In this state no metal or stone can be in solid state, it is in liquid state. The molten lava that comes out of a volcanic eruption does not come from such a deep layer, but from a depth of thirty to forty miles.

The next layer of the mantle is the core. Starting from the bottom of the mantle, a layer of molten iron about 2200 miles deep. The temperature here is terrible. The molten iron is always boiling.

The concentration of iron here is much higher than that of iron found on the surface of the earth. In other words, the surface of the earth is as beautiful as it is

The interior, especially the central area, is just as awful. The temperature and density of this area is beyond our imagination.

Scientists have divided this central region of the earth into two parts. The first is the outer part or the outer part, the second part is the inner part or the inner part. The exterior is about thirteen hundred miles thick. Almost all the elements in this region are in liquid state. What all the matter in the region does in the liquid state, even under extreme pressure, is an absolute wonder to scientists. | The center of the earth after the outer world or the beginning of the inner world. Forty million times more than the pressure on the earth surface, according to the calculations of material scientists over this region, which is about sixteen hundred miles thick. The main component of this region is iron. There is also nickel, cobalt, and some silicon. Density is approximately 14 to 16 times higher than water. And the heat is about half the heat of the sun surface.
