Structure of the Earth
Crust, Mantle, Outer core, Inner core, Lithosphere, Mesosphere
Inner core
an extremely hot, solid sphere of mostly iron and nickel at the center of the Earth
Silicon and Aluminum
found in the upper layer of the Earth's crust.
Crust
hard and rigid, the Earth's outermost and thinnest layer.
Core
innermost portion of the Earth, believed to be metallic. Composed of iron and nickel
Mantle
middle layer of the Earth
Outer Core
the only liquid layer of the Earth
Geodesy
the science that studies and measures the exact size and dimensions of the Earth
Asthenosphere
the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
