Rocky coast landforms, usually characterized by steep sea cliffs, are categorized into two: shore platforms and plunging cliffs (Fig.
Cutting back of a sea cliff by wave action is responsible for the growth of the two types of shore platforms, whereas no appreciable recession occur on plunging cliffs.
The debris supplied from mass movement usually forms talus at the cliff base, the landward margin of shore platforms. The talus deposit protects the cliff toe from erosion until it is transported alongshore and/or offshore by the action of waves and currents; the talus deposit also constitutes a part of the beach sediment that otherwise has been derived from nearby rivers, eroding beaches and/or cliffs.
Shore platforms well develop along the Seven Sisters coast, but the size of beaches at the cliff base changes temporally and spatially.
Lowering of shore platforms located offshore of rapidly receding till cliffs has been extensively studied along the Canadian shore of the lower Great Lakes, (60,97-99,110) where till bottoms are covered with a sparse veneer of sand.

Unit 1, which is formed of gravel and sands, is interpreted as beaches resting on an abrasion shore platform 2-3 m above the present day m.s.l.
These buried the raised beaches and the distal part of the unit extended onto the rocky shore platform. Unit 3 corresponds to peat and swamps formed in the lower parts of the old cliffs and in the newly exposed platform.
The erosive surfaces that constituted the rocky shore platforms and cliffs are polycyclic features that were cut during the Last Interglacial, but were probably also inherited from former interglacial episodes.
