The Earth's crust ranges from 5–70 kilometres (3.1–43.5 mi) in depth and is the outermost layer. The thin parts are the oceanic crust, which underlie the ocean basins (5–10 km) and are composed of dense () iron magnesium silicate igneous rocks, like basalt.The thicker crust is continental crust, which is less dense and composed of sodium potassium aluminium silicate rocks, like granite.

Earth’s internal layering can be defined by this resulting chemical composition. The three main layers of Earth include the crust (1 percent of Earth’s volume), the mantle (84 percent), and the core (inner and outer combined, 15 percent). [1] Crust. The solid crust is the outermost and thinnest layer of our planet.


The Earth's Layers Lesson #1 . The 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 ...


Broadly speaking, the Earth has four layers: the solid crust on the outside, the mantle and the core — split between the outer core and the inner core. The crust is everything we can see and ...
