Figure 2.4: Global map of the continents showing the transition from sub aerial continents to the abyssal plains of the deep ocean basins. The light blue coloration along the edges of the continents represents the relatively shallow bathymetry of the continental shelves. Notice the wide range in width of the continental shelves and that some of the narrowest continental shelves are associated with collisional tectonic margins, whereas the wider continental shelves are associated with passive tectonic margins. For example, compare the shelf width of the collisional west coast of South America with the shelf width of the passive east coast of North America.
