  • Hi there! Come and help me work on my Science project as I continue to learn more about the different layers of the Earth and their essence.
  • I have already researched a few information about it and learned our Earth has 4 layers in it. Now, I am heading off to interview a close friend of my parents who works as a seismologist, a scientist who specializes Earth.
  • It's fine, Justin! I'm happy to have you here. I would gladly teach you about the different layers of the Earth.
  • Good day, Sir Rondina! Thank you for having me here.
  • As for the layers of the Earth, we have the crust, the mantle, the outer core, and the inner core. The crust is thin, cold, and brittle. The mantle is the thickest layer. And the outer core is made from iron and nickel but in liquid form, whereas the inner core is also composed of the same thing but rather in solid metal ball.
  • Let us first discuss the crust. It is as hard as the shell of a hard-boiled egg. Composed of light elements such as silica, aluminum, and oxygen. It is also variable in its own thickness. Under oceans, it is 5 kilometers thick. And beneath its continents, it is 30 to 70 kilometers thick.
  • Next to it is the mantle. It is 3,000 kilometers thick and is 30 kilometers beneath the surface of the Earth. It is composed of iron, magnesium, and silicon. Commonly dense, hot, and semi-solid. It also circulates slowly.
