Coastal cliffs are steep rock formations found along coastlines, created by the erosion of land by waves, wind, and weather. These cliffs can vary in height and composition, often made of limestone, sandstone, or granite. They provide stunning views of the ocean and are home to diverse ecosystems, including various plant and animal species. The formation of coastal cliffs is a gradual process that can take thousands of years. As waves crash against the shore, they wear away the rock, leading to the development of features like sea stacks and bluffs. Coastal cliffs are important for coastal protection and can also be popular spots for hiking and birdwatching.
