La distension a engendr\u00e9 des failles normales qui ont constitu\u00e9 des rifts (grabens), qui sont des reliefs n\u00e9gatifs. Les rifts continentaux (comme les Rifts Est Africains) ont \u00e9volu\u00e9s alors en mer \u00e9troite (telle la Mer Rouge), puis en de vastes oc\u00e9ans (comme l\u2019Atlantique).
