About this document
Earth by bonjourlearnacad is a document available to read on EtoBox.
The Earth consists of four layers: the Crust, Mantle, Outer Core, and Inner Core. The Crust is the thinnest and most studied layer, while the Mantle is semi-solid and causes tectonic plate movement. The Outer Core is liquid metal, and the Inner Core is a dense, solid ball primarily made of iron and nickel.
