Mount Saint Helen

This is a useful video on the history of mount saint helen. Look in particular how mafic/acidic lava erupts and build up in the caldera of Saint Helen. The lava solidifies very fast and erupts mostly as cooling rock when it is pushed up to the surface. Mount Saint Helen is found in the Cascade Range on the North American plate.

yorrike.com's take on continental drift / plate tectonics

Neal Adams' argument

Yorrike's argument

2 video clips for points of discussions during the lesson on continental drift theory in GE4102/3102.

Neal Adams's argument that Earth is growing. Okay, I am biased against this guy quite abit. Yorrike is one guy who is arguing to debunk Neal's 'growing earth' theory.


Link: http://www.yorrike.com/pangea


Here's what we do in class:

Points of discussion:
1. What is Neal's argument on pangea?
2. What evidences did Yorrike draw to debunk Neal?
3. Do you have other evidences you think you have to debunk either party's arguments?

Pay attention to each other in class! We will have a Neal vs. Yorrike debate in class!


One side of the class willbe pro-Neal while the other can be pro-Yorrike. Do research now while you can.

Plate Tectonics (BBC Clip)

This clip explains the mechanisms behind the formation of the continents as well as describes the crustal movements.
