What dextral strike-slip fault is located where the Pacific Plate (along western California) is grinding past the North American Plate?
  1. San Gabriel Fault
  2. San Andreas Fault
  3. Sierra Nevada Fault
  4. Chino Fault
Explanation
Answer: B - The San Andreas Fault is the dextral strike-slip fault that is located where the Pacific Plate is grinding past the North American Plate.

Key Takeaway: When tectonic plates slide past each other along transform faults, they create transform boundaries where they meet. Transform faults are a type of strike-slip fault. This means that the movement of the fault is horizontal. The San Andreas Fault is a well-known strike-slip fault located where the Pacific Plate grinds past the North American Plate. This fault is the cause of the majority of the earthquakes that California is famous for.
