What is Inside of Earth? 

Earth's Interior

Our planet (Earth) is created by some layers like onion .Every layer has it's own unique property, it has four basic layers which are : Crust,Mantle,Outer core,Inner core.

Crust

The crust is the first outer layer, which is almost 50 km dense. A big amount of mountains, plateaus, volcanos, and rocks are present in this layer and this layer is also responsible for the creation of various continents. The crust is divided into two parts "Ocean crust" and "continental crust".

Ocean Crust

This part of the Crust is obviously present on the ocean's surface. You can also say that it is the outer layer of the ocean.  

Continental Crust

Continental Crust is present on dry surfaces and it is responsible for the event of continental Drift, When Tectonic plates (present in this layer) move from their positions then continents are divided and separated from each other and form new continents. These plates also formed earthquakes and Lavos, and these plates are also present in the ocean crust. 

Mantle

The mantle is a huge part of Earth's mass, it is 2900 km dense and 84% of Earth's volume. There is 44% Oxygen,21.5% Silicon,22% Magnesium and Iron, Aluminium, Calcium, Soda, and also Potassium present, which means it is the melting metal mixture which is travel in this layer which a temperature is about 4000-degree centigrade. Mantle has also an outer layer called the "Asthenosphere" which is 400 km dense and releases hot Magma by Lavas, Asthenosphere has another outer layer "Lithosphere" which is 10 km to 200 km long.

Outer Core

After Mantle there is Outer Core which is present in extremely dense, its temperature is about 500-degree centigrade and it mostly consists of melting metals Like Iron and Nickle. It is formed by a 2200 km dense layer where nothing can survive. 

Inner Core

It is the last part of Earth, its temperature is about 6000 degrees centigrade which is equal to the sun's surface temperature and it is about 1250 km dense. It is also made of metals but it is not in liquid form like Outer Core, due to its high pressure it is solid. It has Radioactive elements Like Uranium which make heat here to save our environment from Low temperatures while we live happily and it also saves us from Sun's radiation or solar wind because due to this Core the magnetic field is formed in Outer Core, which saves from Sun's radiation particles or solar wind.
