Layers of the Earth: School Project

Earth is made up of several different layers, each with unique composition, different types of rocks and minerals that make them up, and each with unique properties based on both their composition and depth.

There are four separate layers within the earth. These are the crust, the mantle, the outer core, and the inner core.

Earth’s Crust: Top and thinnest layer. It’s divided into two types, oceanic and continental. The crust is unique in that it’s the only layer made entirely of moving plates.

Earth’s Mantle: The layer right below the crust is the mantle. It has both solid and liquid parts, but most of it is liquid. The solid portion is a component of the lithosphere.

Earth’s Core: The core of the earth splits into two layers, inner and outer. The outer core is fluid, like the mantle. Yet, the inner core is solid.

• Outer Core is extremely hot which causes it to be a liquid.
• Inner Core, despite being extremely hot, is Solid. Its because there’s so much pressure that it prevents the rock from melting. It pushes the atoms together, maintaining a solid state.
