Fjords are long, narrow inlets of the sea between steep cliffs or slopes, typically formed by the action of glaciers. These stunning natural features are found in places like Norway, New Zealand, and Alaska, and are characterized by their deep waters, dramatic landscapes, and unique ecosystems. Fjords are created when glaciers carve through valleys, and once the glaciers retreat, the valleys are filled with seawater. They’re popular for their breathtaking views and rich biodiversity.
