Bays are water bodies located on a land next to the sea or a lake located between two headlands. Waves cut arches and sea stacks that jut into the water. The areas of softer rock retreat, forming bays, while hard rock is eroded slower, resulting in headlands. Also see U-Shaped Valleys, Fjords, and Hanging Valleys as part of Glaciers & Glacial Landforms. Resistant bedrock combined with high-energy wind and wave activity will create a steep profile, whereas easily erodible rocks in low-energy environments will create a more gradual profile, for example, the high cliffs of Kalaupapa National Historical Park (Hawaii) versus the gently sloping rocky coastline of Dry Tortugas National Park (Florida). However, they should be protected from excessive human exploitation. As a result, a section of land known as a headland juts out into the sea.
