Convergent active margins are the most common type of active margin. Transform active margins are more rare, and occur when an oceanic plate and a continental plate are moving parallel to each other in opposite directions. These transform margins are often characterized by many offshore faults, which causes high degree of relief offshore ...
Most of these conventions are supported by active groups of map makers, and have been created and improved through long and serious discussions. The main intentions are: to display efficiently selected data; to create screen, web, print, creation & share friendly maps; to create a wiki style free of nationalism issues.
Maps showing a small geographic area should also have an inset locator map, locating that small geographic area in the context of a larger area, such as a continent or island chain. For example, see this map. Avoid blank space in the image around its main content to give the illusion of a margin around the image.
Active margins characterized by a significant proportion of fine-grained sediment within the incoming section, such as northern Antilles and eastern Nankai, exhibit thin taper angles, whereas those characterized by a higher proportion of sandy turbidites, such as Cascadia, Chile, and Mexico, have steep taper angles. Observations from active ...
Passive continental margins such as most of the Atlantic coasts have wide and shallow shelves, made of thick sedimentary wedges derived from long erosion of a neighboring continent. Active continental margins have narrow, relatively steep shelves, due to frequent earthquakes that move sediment to the deep sea. [19]

Norwegian Margin; US Atlantic Margin; Map showing the distribution of Earth's passive margins with known volcanic and non-volcanic margins distinguished. The margins are marked with color masks where the darkest blues and reds are non-volcanic and volcanic passive margins, respectively.
