1. Opening Activity
What are the three states of matter and how does the molecular motion vary in each?

2. Layers of the Earth

3. Crust 1st layer of the Earth 10 miles deep
Made of rock and loose materials

4. Types of Crust Continental Oceanic Thicker
All land on Earth and shallow seabeds
Oceanic
Under the ocean floor
Dense rock, mostly basaltic

5. Mantle Hot Rock Has two layers Makes up 85% of the Earth’s mass.
Lithosphere
Asthenosphere
Makes up 85% of the Earth’s mass.
Asthenosphere: bottom layer made of plastic like fluid
Lithosphere: made of cold dense rock
3000 degrees celcius

6. Lithosphere
Uppermost part of the mantle
Strong, hard and rigid

7. Outer Core Magma like liquid layer.
Inner core’s heat causes the Outer core to be liquid because it is so hot
Second Largest Layer
Scientists believe the movement of the molten metal causes the Earth’s Magnetic Field

8. Inner Core The innermost layer
Hottest temperature, most density and the most pressure.
Mostly Iron and Nickel
4,000 and 5,00 degrees Celcius

9. Earth’s Magnetic Field
Protects the Earth from solar flares,
Causes the poles

10. Heat Transfer
Thermal energy transferred from a hotter object to a cooler one.
Convection
Conduction
Radiation

11. Convection Transfer of heat by the movement of fluid
Occurs in liquids and gases
Circular motion

12. Conduction Transfer of heat between two substances in direct contact
Works well in some solids (metals)

13. Radiation Transfer of heat energy by electromagnetic waves
Felt as heat
