The Pacific Plate is currently being subducted under the North American Plate. Subduction zones are when one plate is being forced under another at a convergent boundary (where two plates collide). When the Pacific Plate is being subducted under the North American Plate, the crust of the Pacific Plate melts, and creates volcanoes along the edge of the North American Plate. So, the relative motion of the two plates is that they are converging, or moving together.This same process is happening at the South American and Nazca Plates.
In the Pacific northwest between Canada and Oregon.
The fault between the North American plate and the Pacific plate is the San Andreas Fault.
Pacific Ocean
The Pacific Plate and the North American Plate border each other along the coast of California. The Pacific Plate is slowly moving northwest relative to the North American Plate, which can lead to seismic activity in the region, such as earthquakes.
the key interface between the north American realm and pacific rim
That would be the Atlantic Ocean. Pacific is on the other side, by California. Pacific
