This is why most of the plate has an elevation above sea level and is seen as dry land on which humans and terrestrial animals can live. For example, the North American plate has continental crust (essentially the land area of North America) at its core; this is surrounded on most sides by oceanic crust. The friction between the plates prevents the subducting oceanic plate from sliding smoothly.
