Coastal cliffs are steep rock formations found along coastlines, where land meets the sea. They are formed through processes like erosion, where waves and weather wear away the rock over time. These cliffs can vary in height and composition, often showcasing layers of different types of rock. Many coastal cliffs provide habitats for various plants and animals, including seabirds that nest in the rocky crevices. They also offer stunning views of the ocean and are popular spots for hiking and photography. Coastal cliffs can be found in many regions around the world, such as the White Cliffs of Dover in England and the Big Sur coastline in California.
