I have attached a PPT for you in order to answer these two questions. they must be answered from the power point not somewhere else!

1) List in order from the surface to the center the four main layers of the earth. Give their composition, thickness and how each behave (as a solid or liquid).

2) Subdivide the crust in to its two types and subdivide the mantle into its three main layers. For both the crust and the mantle, describe the composition and characteristics of each sublayer.
