A fjord is defined as a long narrow inlet of the sea that is typically flanked by steep cliffs or mountains. This geological feature is formed by the submergence of a glaciated valley, where a glacier has carved out a deep U-shaped valley that subsequently fills with seawater. Fjords are often characterized by their dramatic scenery, with steep, often vertical cliffs on either side, and they are found in regions with a history of glaciation, such as Norway, New Zealand, and parts of Canada.

The other options describe different concepts. The second choice refers to a phenomenon related to atmospheric conditions, such as fog or smog, which affects visibility but does not pertain to geological formations. The third choice describes a food chain scenario in ecology, illustrating the predator-prey relationships among organisms but not relating to geological features. The last option, while also rooted in ecology, details a community structure involving multiple food chains, which does not connect to the definition of a fjord. Understanding the unique characteristics of a fjord emphasizes the interplay between geological processes and marine environments.
