1. Earth Layer

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

3. 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.

4. 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.

5. 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.

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

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

8. Outer Core
The Outer Core is molten
