The geographical feature characterized by a narrow inlet between cliffs is a fjord. Fjords are formed by glacial erosion and are typically found in coastal regions, where ancient glaciers have carved deep valleys that are subsequently flooded by rising sea levels. They often feature steep cliffs rising sharply from the water, creating dramatic and breathtaking landscapes. Fjords can be found in various locations around the world, including Norway and New Zealand, and provide stunning scenery along with opportunities for outdoor activities such as hiking and kayaking.
