Structure of Earth's Layers and Explanation (Complete) – Earth is the place where we live, the place where we stand and the place where we have been enjoying its beauty. Earth is the only planet of the solar system that is inhabited by humans and other living things.

At the beginning of its formation, the earth originated from a celestial body that was incandescent & very hot. Then, after millions of years, the earth slowly cools, and parts of the earth's crust become frozen even though the inside is still hot.

Structure of Earth's Layers and Explanation (Complete)

Earth has a skin of unequal thickness. On the plains or continents it is thicker than under the ocean. The earth itself has layers consisting of several layers, including the following:

Structure of the Earth's Layers

The following is an explanation of some of the layers of the earth's structure:

Barrier

Is the layer of the earth's core composed of nife layers (niccolum: nickel and ferrum: iron). It has a radius of approximately 3,470 km and an outer boundary of approximately 2,900 km below the earth's surface.

Intermediate Layer

Is a layer that is above the 1,700km thick nife layer. Its specific gravity averages 5 gr/cm3. The intermediate layer is also called the asthenosphere (mantle) which is a high-temperature & incandescent liquid material.

lithosphere

Is a layer that lies above the intermediary layer, with a thickness of up to 1,200 km. Its specific gravity averages 2.8 gr/cm3. The lithosphere is the earth's crust which consists of two parts, namely:

Damn layer

Namely the layer of the earth's crust which is composed of the metals silicon and aluminum, and their compounds in the form of siO2 & AI2O3. In this layer there are sedimentary rocks, andesite, granite, types of metamorphic rocks and other rocks found on the continents. This unlucky layer is also called the crust layer which is dense and stiff with a thickness of approximately 35 km. For this crust itself is divided into two:

  • Continental crust ie a solid object consisting of granite igneous rock on top and basalt igneous rock on the bottom.
  • Oceanic crust namely a solid object consisting of marine sediments at the top, which is then volcanic rocks underneath and the bottom is composed of gabbro & periodic igneous rocks. For this crust occupies as oceans.

Sim layer

Namely the skin layer by silicon-magnesium metals in the form of SiO2 and MgO2 compounds. This layer contains iron and magnesium, namely ferromagnesium minerals & basalt rocks. This layer is a material that is elastic and has a thickness of about 65km.

So, that's a brief explanation Structure of Earth's Layers and Explanation (Complete), Hope it is useful. That is all and thank you.
