Earth Layer

Composition of the Earth Three layers: crust mantle Core #5 Temperature and density increases as depth increases.  

Crust #6. The composition of the earth changes with depth and layers. #7. The crust is the upper part of the rigid lithosphere and is of different composition under land as opposed to the ocean floor.

Mantle 66% of mass of Earth #11 Below the rigid lithosphere, the mantle consists of hot rock of tar-like consistency, which slowly moves or flows.

Lithosphere #10 The Lithosphere is the coolest layer of the earth. #12 The lithosphere is the smallest layer of the Earth and it comprises 1% of the Earth’s total mass.

Core Hottest layer of Earth 33% of the Earth’s mass Made of Outer core Inner core

Inner Core Inner core is solid Inner core is more dense The most dense layer of the earth

Outer Core The Outer Core is molten
