Fjord vs. Other Landforms: Understanding What Isn't a Fjord

* A river delta. A river delta is a landform that is formed at the mouth of a river where the river meets the sea. River deltas are typically formed by the deposition of sediment that is carried by the river.

* A lake. A lake is a body of water that is surrounded by land. Lakes can be formed by a variety of processes, including the damming of a river, the melting of a glacier, or the subsidence of land.

* An ocean. An ocean is a large body of salt water that covers much of the Earth's surface. Oceans are formed by the collection of water from rivers, lakes, and other sources.
