Answer:
The North American Plate moves in roughly a southwest direction away from the Mid-Atlantic Ridge at a rate of about 2.3 centimeters (~1 inch) per year. At the same time, the Pacific Plate is moving to the northwest at a speed of between 7 and 11 centimeters (~3-4 inches) a year.
Explanation:
The fastest moving tectonic plate on Earth?
The Cocos and Nazca plates (in the pacific ocean) are right now the quickest, moving at over 10 cm/yr. However typical plate movements are less quick, at rates about 2-3 cm/yr.
How fast is the North American plate moving?
The North American plate is moving to the west-southwest at about 2.3 cm (~1 inch) per year driven by the spreading center that created the Atlantic Ocean, the Mid Atlantic Ridge.
