What is a description of steep ocean inlets?

Steep ocean inlets, often referred to as fjords, are narrow, deep coastal valleys formed by glacial activity, characterized by steep cliffs on either side. These inlets typically have a U-shaped profile and can be quite deep, with water levels often exceeding the surrounding land. The dramatic topography creates stunning landscapes, where freshwater rivers meet the ocean, and they are often rich in marine biodiversity. Fjords can serve as important habitats for various species and are popular destinations for tourism and recreation.
