Amazing theory of what’s inside the earth

Inside the earth
The inner part of the Earth consists of four layers , three solid and one liquid – not magma, but molten metal , which is almost as hot as the surface of the Sun.

The deepest layer is a solid iron ball about 2400 km in diameter. Although this inner core is very hot, the pressure in it is too high and the iron cannot melt.

Iron is not pure – scientists believe that it contains sulfur and nickel , as well as a small percentage of other elements. Estimates of its temperature range from 5,000 to 7,000 degrees Celsius.

Above the inner core is the outer core, the shell consists of liquid iron. This layer is colder, but still very hot from 4,000 to 5,000 degrees Celsius. It creates the Earth’s magnetic field and is about 2,300 kilometers thick .

The next layer is the mantle . The stone is so hot that it flows under pressure like road tar .

The thickness of the mantle is about 2900 kilometers, and it is divided into two layers: the upper and lower mantle.

Cork is the outer layer of the Earth. This is a familiar landscape in which we live: stones, soil and the seabed .

The streams inside the mantle smashed the crust into blocks called plates, which move slowly , colliding to build mountains or to form a new seabed.

With the exception of the crust, the inner part of the Earth cannot be explored by drilling holes for taking samples. Instead, scientists observe how seismic waves from earthquakes bend, bounce, accelerate, or linger in various layers.
