A fjord is a deep, narrow inlet of the sea that is surrounded by steep cliffs or slopes. These natural formations are typically created by the erosion of glaciers, which carve out valleys that later fill with seawater. Fjords are often characterized by their stunning scenery, featuring dramatic landscapes and clear waters. Fjords are commonly found in regions with a history of glaciation, such as Norway, New Zealand, and Chile. They can vary in size and depth, with some fjords extending many miles inland. The unique ecosystems within fjords support diverse marine life, making them important for both tourism and conservation.
