The continental margins, whether active or passive, may be divided into four conditions:
Use the map below to select and visit the condition and area you wish to explore.
Those portions of the outer edges of
the continents that lie under water
are referred to as the continental
margins. These margins are of two
types, depending on the tectonic
condition that they represent.
Margins located at the edges of
diverging plates are called passive
margins as these conditions are
characterized by relatively little
earthquake or volcanic activity.
Margins at the edges of converging
plates are called active margins.
These locations see frequent
volcanic or earthquake activity.
Passive margins are typical of the
Atlantic, while active margins are
common in the Pacific.
