NettetThe Four Layers The Earth is composed of four different layers. Many geologists believe that as the Earth cooled the heavier, denser materials sank to the center and the lighter materials rose to the top. Because of this, the crust is made of the lightest materials (rock- basalts and granites) and the core consists of heavy metals (nickel and iron). The crust … Nettet10. apr. 2024 · But let’s talk about the first question first. Under the oceans, the thickness is fairly consistently just 5 km, which is remarkably thin. On land, however, it averages about 30km but can be as much as 100km. Considering that the distance from the surface to the centre of the earth is about 6 400 km, a crust of even 100km is strikingly thin. NettetIn plate tectonics: Earth’s layers.
