1. The earth

2. 3d Structure of the earth.

3. Crust less dense than what is below it. Etc…
Mohorovicic Discontinuity (Moho) – where the density increases at the bottom of the crust. Boundary between the lithosphere and aesthenosphere
Note, reverse topography at bottom of crust.

4. Note relative thicknesses of the crust
Note relative thicknesses of the crust. Also note that the lithosphere includes the crust and a bit of the upper mantle.

6. Oceanic crust Oceanic (mafic) rocks. Continental (felsic) rocks
Denser than felsics
Darker colored
Less silica, more iron/Mg
basalt
Continental (felsic) rocks
Lighter than mafics
Lighter colored
More silica, less iron/Mg.
Granite

7. Plate tectonics
The crust of the earth is, basically, a bunch of pieces floating around on the asthenosphere.
These plates interact, forming surface topography
- an excellent overview of plate tectonics. Might be a good thing to read while studying.

11. Continent – continent convergence

12. Ocean-ocean convergence

13. Ocean-continent convergence

14. C-C to O-O divergence

16. Transform boundary

18. San Andreas in CA

21. Goto google earth and look at all types of plate boundaries

22. Talk about hot spots Hawaii and the Galapagos
Columbia plateau, snake river plain, yellowstone
