Headlands are elevated landforms that extend into a body of water, often creating a prominent point along a coastline. They are typically characterized by steep cliffs or slopes and can be formed through processes such as erosion and sediment deposition. Headlands serve as natural barriers, protecting the shoreline from strong waves and currents. These landforms are often rich in biodiversity, providing unique habitats for various plant and animal species. The surrounding marine environment can also be influenced by headlands, as they can create sheltered areas known as bays or coves. Popular examples of headlands include Cape Cod in the United States and Land's End in the United Kingdom.
