The North American Plate includes several countries, prominently:
- United States – The majority of the continental U.S. lies on this tectonic plate.
- Canada – Almost all of Canada is situated on the North American Plate.
- Mexico – The northern part of Mexico is also part of this tectonic plate.
In addition to these primary countries, various regions of Central America, including parts of Guatemala and Belize, extend into the North American Plate. The plate also covers parts of the Atlantic Ocean floor, extending to the mid-ocean ridges and impacting geological activity. Understanding the boundaries of the North American Plate is important for studying seismic activity, as tectonic movements can lead to earthquakes in these regions.
