1. Plate Tectonics: Continental Drift
Chapter 5:

2. Composition versus Structure
Crust
Mantle
Core
Lithosphere
Asthenosphere
Mesosphere
Outer Core
Inner Core

3. Breakdown of the Earth
Lithosphere = Crust and upper part of mantle, solid
Asthenosphere = Mantle, convection currents, putty
Outer core = core, liquid
Inner core = core, solid

4. Foldable Earth Questions
Challenge: What is the Diameter of the earth?
How do you solve this problem?
Add all the layers
Inner core is just the radius

5. Inner core vs outer core
How deep in the earth is the border between the outer core and inner core?
As we journey towards the center of the Earth, what happens to the temperature and pressure? Why?

6. Inner Core The temperature on the inner core is 6,000 degrees Celsius
Why is the outer core liquid while the inner core is solid?

7. Continental Drift Alfred Wegener
Theory that continents can drift apart and towards one another
