À la différence des marges stables, les marges actives, comme celles de l'océan Pacifique, sont caractérisées par une forte activité sismique et volcanique et jouent un grand rôle dans la tectonique des plaques(zones de subduction). Généralement, le plateau continental est réduit ou absent ainsi que le glacis et, dès le littoral, le talus continental plonge jusqu'à une profondeur de 5 000 à 10 000 m pour former une fosse océanique marginale [...] 5, record 1, French, - marge%20active

When two plates move toward one another, they form either a subduction zone or a continental collision. This depends on the nature of the plates involved. In a subduction zone, the subducting plate, which is normally a plate with oceanic crust, moves beneath the other plate, which can be made of either oceanic or continental crust. 3, record 3, English, - subducting%20plate
Record number: 3, Textual support number: 2 CONT
Separation of the crust is a common occurrence when continents collide. It happens when the subsiding plate of a continent reaches the subduction zone faster than the adjacent areas. 4, record 3, English, - subducting%20plate
