WebWe can use our knowledge of how gravity works to calculate the mass and overall density of the Earth. We can time seismic waves from earthquakes to determine how fast they move through the core. Then we compare those numbers to materials we can study in the laboratory. An alloy of iron and nickel matches the evidence. WebEarth is composed of multiple layers, which can be defined either by composition or by mechanical properties. The crust, mantle, and core are defined by differences in composition. The lithosphere, asthenosphere, mesosphere, and outer and inner cores are defined by differences in mechanical properties.
