Document Summary
Epsc201 2006 final exam review section 3&4: the san andreas fault is a transform fault. In the new idea, the relative position of the two ridges remains unchanged, but the continents (green) move further apart. In the old idea, the ridge and continents both move relative to each other. It is easier to move continents apart if the drift is due to many small slips, instead of one big slip. The main message is that the only movement occurring is in-between the ridges, because outside of the ridges, the crust is moving in the same direction at the same speed. Key assumption the top and bottom ridges are spreading at exactly the same rate: describe the most important properties of diamond and graphite (one for each mineral) and relate these properties to molecular structure. We started talking about diamonds last class; are purely carbon. Every carbon atom is bonding to every other carbon atom.
