8. Plate Tectonics
A relatively recent theory that the Earth's crust is composed of rigid plates that move relative to one another.
Plate movements are on the order of a few centimeters/year - about the same rate as your fingernails grow!
There are 3 types of plate boundaries:
1. divergent
2. convergent
3. transform

9. Continental Divergent Boundary
Example: Red Sea / E. African Rift

10. Oceanic Divergent Boundary
Example: Mid-Atlantic Ridge
