Sea cliffs can be ‘hard’, with enduring rock faces of plunging granite, sandstone, basalt or limestone, or ‘soft’, with crumbling, folding slopes of shale and mudstone.

Seabird colonies are typically home to a range of seabirds. Tightly packed, raucous Guillemots and Kittiwakes nest on ledges alongside Gannets, Shags and Cormorants as well as gulls, Fulmars and Razorbills.
