![]() I) No need to go through the whole hassle of using newspapers and tissue papers. This will save your time for the following actions – Another idea that comes to mind is using the Thermocol for the entire model, i.e., complete replacement of football with a sphere of Thermocol, or better known as styrofoam.It can even beat cardboard for its lightweight and density and white color, which are good attributes when making such 3D creative models. My suggestion is thatThermocol also has the same capability of providing structural support as Cardboard. Right off the bat, the first alternative that comes to my mind is, using Thermocol instead of wherever you used cardboard.Other ways to showcase – Layers of the Earth Project ? High pressure at high temperatures converts liquid to solid. But, there is an explanation of why it is so. Though it is also made up of Iron and Nickel, their state is not liquid but solid. Imagine living over something that has been equated to the Sun, the hottest star in all of the Milky Way Galaxy. It is speculated that the temperature may be comparable to that of the Sun itself. The final and innermost layer from the periphery and first from the core is the hottest of all. The function of this magnetic field is to shield us from the Sun’s harmful radiations. The presence of metals in this layer creates and sustains a magnetic field. This layer is very significant to Earth, and more importantly, to us. These solid metals exist as liquids in the core. The outer core components are Iron and Nickel. The third layer from the periphery and the second from the core have been recorded to have a temperature of over 5000℃. Another layer that is not very defined and is actually a combination of crust and mantle is the ‘tectonic plates.’ The movement of these is the cause of Earthquakes.Īs we move deeper into the bowels of the Earth, the temperature soars unimaginably.Even though technology has developed at lightning speed over the past two decades, traveling to the inner earth is still impossible. This is the last layer that separates us from the inner earth regions, which have not been reached to date. It is mainly composed of minerals and mineralized rock of silica, magnesium, and iron. The layer second from the periphery and the third from the center. This is because the sea is already present below the land level and is much nearer to the mantle. On land, it ranges from 30-70 km depending upon the point it is measured from, while in water, it is a mere 5 km. It is simply the ground or soil we step on. The thinnest and least dense layer of all 4. The layer first from the periphery and the last from the center. ![]()
