Students construct the layers of the Earth (inner core, outer core, mantle, and crust) using an Oreo, some chocolate syrup, and a small candy piece. This is such an exciting activity to use when teaching a lesson on the layers of the Earth.
1) CRUST: Oceanic & Continental (about 3 to 50 miles thick), plus The Mohorovicic Discontinuity = (The Lithosphere: solid) 2) Mantle: a) The Upper Mantle, magma molten rock, b )The Lower Mantel (about 1,796 miles thick 2,000 degrees F) = Asthenosphere (Flows around the outerr core) 3) Outer Core - Molten Metal (11,000 degrees F) that flows around the inner core & is thought to cause Earth's magnetic field. 4) Inner Core - Hot solid mostly iron, with some nickel, (like meteorites), may spin.
What would it be like to take a journey to the center of the earth? Well, you'd travel through the Earth's four concentric layers: inner core, outer core, mantle and crust. The crust is the outer layer of the earth. It is a thin layer between 0-60 km thick. The crust is the solid rock…
NuSTAR NASA telescope has found evidence that a massive star exploded in an unbalanced way, ejecting material in a direction and the core of the star in another. The results offer the best evidence that exploding stars of this type, called Type II or core collapse supernovae, are asymmetric, a phenomenon that had been difficult to prove so far, NASA said in a statement.
