WebThe 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 is … WebJan 17, 2024 · The Earth's lithosphere is extremely active, as continental and oceanic plates constantly pull apart, collide and scrape alongside each other. When they do, they form faults. There are different types of faults: …
