Strait

A strait is a naturally formed, narrow, typically navigable waterway that connects two larger bodies of water. Most commonly it is a channel of water that lies between two land masses. Some straits are not navigable, for example because they are too shallow, or because of an unnavigable reef or archipelago. Straits are also known to be loci for sediment accumulation. Usually, sand-size deposits occur on both the two opposite strait exits, forming subaqueous fans or deltas.

Terminology[edit | edit source]

The terms channel, pass or passage, can be synonymous and used interchangeably with strait, although each is sometimes differentiated with varying senses. In Orbaal firth or kyle are also sometimes used as synonyms for strait.

Many straits are economically important. Straits can be important shipping routes and wars have been fought for control of them.

There are a few artificial channels, called canals, that have been constructed to connect two bodies of water over land. Although rivers and canals often provide passage between two large lakes or a lake and a sea, and these seem to suit the formal definition of strait, they are not usually referred to as such. The term strait is typically reserved for much larger, wider features of the marine environment. There are exceptions, with straits being called canals.

Comparisons[edit | edit source]

Straits are the converse of isthmuses. That is, while a strait lies between two land masses and connects two larger bodies of water, an isthmus lies between two bodies of water and connects two larger land masses.
