This movement causes:

* Subduction along the west coast of North America, where the denser oceanic plate (Pacific Plate) slides beneath the continental plate (North American Plate). This results in the formation of the Cascade Range and the Aleutian Islands.

* Transform faulting along the San Andreas Fault, where the Pacific Plate is moving north relative to the North American Plate. This movement causes earthquakes.

* Collision with the Eurasian Plate in the North Atlantic, resulting in the formation of the Mid-Atlantic Ridge.

It's important to note that plate movement is a continuous process, and the exact direction and speed of the North American Plate can vary over time.
