The eastern boundary of the North American plate is primarily characterized by a passive margin, where the continental crust transitions into oceanic crust along the Atlantic Ocean. This type of boundary is marked by a lack of significant tectonic activity, as there are no major plate interactions such as subduction or collision. Instead, it features features like broad continental shelves and sedimentary basins formed by the gradual separation of the North American plate from the Eurasian plate.
