Strait A naturally formed, narrow, typically navigable waterway that connects two larger bodies of water

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.

Island Any piece of sub-continental land that is surrounded by water

An island or isle is any piece of sub-continental land that is surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. A grouping of geographically or geologically related islands is called an archipelago, such as the Philippines.

Graemsay island in the western approaches to Scapa Flow, in the Orkney Islands of Scotland

Graemsay is an island in the western approaches to Scapa Flow, in the Orkney Islands of Scotland. The island has two lighthouses.

Clestrain Sound lies in the western entrance to Scapa Flow. Like other seaways within the Orkney Islands, Clestrain Sound has been recognized for many years to be warmed by the North Atlantic Drift current. [2]

Scapa Flow bay

Scapa Flow is a body of water in the Orkney Islands, Scotland, sheltered by the islands of Mainland, Graemsay, Burray, South Ronaldsay and Hoy. Its sheltered waters have been used by ships since prehistory and it has played an important role in travel, trade and conflict throughout the centuries – especially during both World Wars.

Sound (geography) A long, relatively wide body of water, connecting two larger bodies of water

In geography, a sound is a large sea or ocean inlet, deeper than a bight and wider than a fjord; or a narrow sea or ocean channel between two bodies of land.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
