12. the sense of motion along the san andreas fault is typical of a plate boundary. a. divergent b. convergent c. transform d. none of the above

c. transform

Explanation:

The Andreas Fault is a major fracture of the Earth’s crust in extreme western North America, according to the theory of plate tectonics, it represents the transform (strike-slip) boundary between the Northern Pacific and the North American plates

Considering this information we know that plates can move towards each other (convergent), move away from each other (divergent), and slide alongside each other (transform). In the San Andreas Fault, two tectonic plates slide alongside each other causing earthquakes, therefore the correct answer is c. transform.

I hope you find this information useful and interesting! Good luck!

reflecting point a across the origin negates both of its coordinates.
