Correct answer: two plates moving past each other.

Brief explanation: the San Andreas Fault is a transform (strike-slip) fault that marks the boundary where the Pacific Plate and the North American Plate slide horizontally past one another. It developed as the earlier subduction of the Farallon Plate ended and the Pacific–North America plate motion became mainly lateral (beginning ~20–30 million years ago). The fault’s frequent earthquakes are a consequence of that plate motion, not the cause.
