San Andreas is an example of a transform fault boundary in the "west coast" of the United States.
This transform fault joins the "divergent boundary" in the "Cascadia subduction zone" with the "Gulf of California".
EXPLANATION:
A transform fault boundary is a boundary of the plates where the "motion" is for the most horizontal part.
The fault is connected to "another transform" or a "subduction zone" and ends abruptly. These types of faults are typically hidden in deep ocean ridges.
