The earth element has made many scientists curios about it and does various kinds of experiments in order to find the new element which composes it. The third element in earth core is the one which is learned by the scientists nowadays. They are even confused to unveil the mystery of this element for decades. However, recently the team from Japan has made big efforts in order to reveal the identity of this third element so far. Now, this Japan team has got the answer and they stated that the third element in earth is none other than silicon.
The scientists have found the ways to break the mystery in the centre of planet for several decades after find that there is other thing than iron and nickel. The Japanese scientists believed that they have created the identity of losing element in earth core.
The leader of Scientists form Tohoku University, Eiji Ohtani, believed that silicon is the main element whose weight is about 5 percent from the earth. The silicon itself is known to be dissolved in the iron-nickel mix. To know the whether this is the right element or not, the scientist measures the sound speed of aluminium alloy compound in high pressure and temperature which is relevant with the earth core.
In order to know this earth element, Eiji Ohtani and the team create a mix of iron and nickel and blend it with silicon for the experiment before use them as the object to high pressure and temperature which is believed exist in the core of earth. Then, they find a mix which is suitable to what can be seen in the earth interior with the seismic data. However, Ohtani stated that there are more works required in order to confirm the existence of silicon and this also trigger people to think that there will be other elements which compose the earth.
The most in-depth of earth is expected to be a solid ball with the radius about 1.200 km. The scientists analyse how the seismic wave can pass this area in order to inform them with anything form its look. To know deeper about this earth element, the prior scientists have shown about this matter which consist of iron and make the weight about 85 percent and nickel that contribute about 10 percent of earth core. However, the remaining percentage then confuses the scientists again.Photo credit: NASA Goddard Photo and Video via Foter.com / CC BY
