A cliffed coast, also known as an abrasion coast, is one in which marine action has resulted in steep declivities known as cliffs. Transportation and deposition processes produce distinctive coastal landforms (beaches, recurved and double spits, offshore bars, barrier beaches and bars, tombolos and cuspate forelands), which can be stabilised by plant succession. First, tidal currents transport massive quantities of sediments and even erode the rock bed. Soft rock bands, such as clay and sand, are weaker, so they can be quickly eroded. Discordant coastline occurs where bands of differing rock type run perpendicular to the coast. It is often a cliff or other elevated landform overlooking a sea or ocean.
