Inlet
Encyclopedia
An inlet is a narrow body of water between islands or leading inland from a larger body of water, often leading to an enclosed body of water, such as a sound
, bay
, lagoon
or marsh
. In sea coasts an inlet usually refers to the actual connection between a bay and the ocean
and is often called an "entrance" or a recession in the shore of a sea, lake or river. A certain kind of inlet created by glaciation is a fjord
, typically but not always in mountainous coastlines and also in montane lakes.
Complexes of large inlets or fjords may be called sound
s, e.g. Puget Sound
, Howe Sound
, Karmsund
(sund is Scandinavian for "sound"). Some fjord-type inlets are called canals, e.g. Portland Canal
, Lynn Canal
, Hood Canal
, and some are channels, e.g. Dean Channel
, Douglas Channel
, Amsterdam Channel.

A bay is an area of water mostly surrounded by land. Bays generally have calmer waters than the surrounding sea, due to the surrounding land blocking some waves and often reducing winds. Bays also exist as an inlet in a lake or pond. A large bay may be called a gulf, a sea, a sound, or a bight...

Ocean
An ocean is a major body of saline water, and a principal component of the hydrosphere. Approximately 71% of the Earth's surface is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas.More than half of this area is over 3,000...

Fjord
Geologically, a fjord is a long, narrow inlet with steep sides or cliffs, created in a valley carved by glacial activity.-Formation:A fjord is formed when a glacier cuts a U-shaped valley by abrasion of the surrounding bedrock. Glacial melting is accompanied by rebound of Earth's crust as the ice...
