2. Assume that the spreading north pole for the North American Plate corresponds exactly with the geographic north pole of the Earth and determine horizontal spreading rates at 5 different locations on the Mid-Atlantic Ridge if the angular speed () of the North American Plate is 1.010-8 radians per year. How do your calculations compare with GPS-determined rates for the North American Plate, and what are the implications of your findings?
