 Abrasion platforms are shore platforms where wave action abrasion is a prominent process.If it is currently being fashioned, it will be exposed only at low tide, but there is a possibility that the wave-cut platform will be hidden sporadically by a mantle of beach shingle (the abrading agent).If the platform is permanently exposed above the high-water mark, it is probably a raised beach platform (aka, marine terrace), which is not considered a product of abrasion but may be undercut by abrasion as sea level rises.
