A good review… Use this PowerPoint to review the concepts that include all the layers of the Earth. This will be one helpful source to prepare for the Earth’s Structure Quiz.

This layer is made of granite and basalt… A – Mantle B - Crust

This layer is the densest layer… A – Core B – Mesosphere

This layer is broken into pieces called tectonic plates… A – Mesosphere B – Lithosphere

This layer is molten and causes the magnetic poles… A – Inner Core B – Outer Core

This layer takes up the majority of Earth’s mass… A – Mantle B – Core

These layers are divided based on the elements they are made of… A – Crust, mantle, and core B – Lithosphere, Asthenosphere, Mesosphere, Outer Core, and Inner Core

This layer is made of Silicon (Si), Oxygen (O), and Aluminum (Al) and has a low density… A – Asthenosphere B – Crust

This layer is the rocky and rigid layer… A – Mesosphere B – Lithosphere

This layer is made of Nickel (Ni) and Iron (Fe)… A – Core B – Mantle

These layers are divided based on their physical state… A – Crust, mantle, and core B – Lithosphere, Asthenosphere, Mesosphere, Outer Core, and Inner Core

This is the dense and hard layer of the mantle… A – Asthenosphere B – Mesosphere

This is the layer on which the plates move… A – Asthenosphere B – Mesosphere

This layer is “flowing” similar to glass… A – Asthenosphere B – Lithosphere

This layer is under the most intense pressure… A – Inner Core B – Mesosphere

This layer is composed of Silicon (Si), Oxygen (O), and a lot of Magnesium (Mg)… A –Mantle B – Core
