WebAt Land’s End, the coastal landscape is notoriously wild and the weathering action of waves, wind and salt-spray has produced classic rocky coastal scenery with rock arches, sea stacks, off-shore rock islands and rugged cliffs ranging in height from 61 to 122 metres high. The cliffs around Land’s End are comprised of two forms of granite. WebCoastal erosion may be caused by hydraulicaction, abrasion, impact and corrosionby wind and water, and other forces, natural or unnatural.
