Cliffs are steep, vertical, or nearly vertical rock faces that can be found along coastlines, mountains, and riverbanks. They are formed through processes like erosion, weathering, and geological activity, which shape the landscape over time. Cliffs can vary in height and composition, often made of materials such as limestone, granite, or sandstone. Cliffs provide important habitats for various wildlife, including birds, plants, and insects. They also offer stunning views and recreational opportunities, attracting hikers and climbers. Famous cliffs, like the White Cliffs of Dover in England or El Capitan in Yosemite National Park, are popular destinations for tourists and nature enthusiasts.
