Iron ice froze in the inner core of the earth. On the outer part of this core, iron-like iron particles keep falling and form a solid layer. Researchers have claimed this by studying seismic waves. They say that the weight of these iron particles is more than the snowflakes falling from the sky.
In a study published in the journal JGR Solid Earth. Researchers said that iron particles melt from the outer core part of the Earth as the snowflakes collect on the earth and then transform into a solid form. Go away and cover the whole part.
Analysis Of Signs Of Seismic Waves
Researchers from the US University of Texas said, ‘For this study, they analyzed the signals of seismic waves. In the meantime, the researchers found that the seismic waves when they passed from their center to the outer core were much slower than earlier estimates, but as the waves passed from the inner core towards the eastern hemisphere, their speed was relatively faster. ‘
The reason for the researchers said that the layer of iron particles present in this part of the inner core is very thin. Causing the seismic waves to propagate faster. While the thickness of this layer is greater in the western part of the inner core. Therefore, seismic waves do not propagate at a rapid rate in the Western Hemisphere.
Researcher Nick Siegert of the University of Tennessee. The USA, involved in the study, said that the process of depositing iron particles in the interior of the Earth is like a drop of rain falling on the Earth. From the area of the outer core to the room of iron particles in the inner core Falls and forms a layer.
Earth Divided Into Three Layers
The internal structure of the Earth made up of many layers. The topmost crust is a solid layer, the intermediate mantle is a very thick layer. And the outer core (core) is liquid and the inner core is in solid-state. The internal structure of the Earth mainly divided into three parts.
It is the topmost layer of the Earth with an average depth of up to 24 km and this depth varies between 5 km to 70 km. Under the seas, it is in the form of less thick marine basaltic crust. While its expansion below the continents is found to a greater depth. The deepest depth founds below the mountains.
The mantle extends to a depth of 2890 km after the crust. Vascular currents run here due to which there is motion in the plates of the terrain.
The third and last layer of the earth. It consists of nickel and iron particles. It is 2890 km deep to the center of the Earth. Its density ranges from 11-12 and the average density is 13 grams per cubic cm. The load of the core is about 1/3 of the weight of the earth.
