San Andreas Fault -Tectonic setting

Tectonic setting of the San Andreas Fault. Modified from U.S. Geological Survey

Questions for thought

  1. Why is the Pacific Plate moving to the northwest?
  2. Is the North American Plate actually moving to the southeast?
  3. Most transform faults are found along midocean ridges. They cut through oceanic crust and are located entirely in the oceans. The San Andreas Fault cuts through a continent. Why is the San Andreas Fault considered a transform fault? What does this exceptional fault have in common with others?
