(Please read the San Andreas Fault page first.)
It is a crust that is primarily made of basalt (oceanic crust) or granite (continental crust).
Where two plates slide past each other (Tasa Graphic Arts).
Is where two plates meet.
The San Andreas Fault is located on the transform boundary where the Pacific Plate and the North American Plate meet (Tasa Graphic Arts). The San Andreas fault mostly on land and most plate boundaries are under water so this is a prime place for geologists to study the plate tectonics(“Information and Resources about the San Andreas Fault”). The transform boundary creates a lot more fault lines like the San Jacinto fault, San Gabriel fault and many more (USGS), but the San Andreas fault is the biggest, stretching from Baja California to past San Francisco.
I chose the San Andreas fault because it has always fascinated me that we are slowly moving south on the North American plate and, Los Angeles is slowly moving north on the Pacific plate. It is very interesting to see how the plates are moving (Kluft). Eventually part of California is going to a very big island.
