Headland geography refers to coastal landforms that project into a body of water, typically the ocean. These formations are characterized by steep cliffs and rugged terrain, often created through processes like erosion and wave action. Headlands can serve as natural landmarks and are often found at the edges of bays or along coastlines. The formation of headlands is influenced by the type of rock in the area, with harder rocks resisting erosion better than softer rocks. Common examples of headlands include Cape Cod in the United States and Land's End in the United Kingdom. These features play a significant role in coastal ecosystems and navigation.
