This paper considers the palaeoplain and the basal unconformity to be the same surface. It presents a hypothesis for continental passive margins that integrates the geomorphology near the continental boundary with the offshore geomorphology. This model explains the parallel structures of continental divide, present coast line, and continental edge. It also explains the creation of the basal unconformity in a short time, and the comparative volumes of onshore erosion and offshore sedimentation. Onshore, the model explains the modifications of drainage and the great escarpments that are characteristic of passive margins
