In the UK we call it the Irish Sea.
Ireland is an island containing the Republic of Ireland and Northern Ireland. Nearby is the island of Britain, containing England, Scotland and Wales. The Isle of Man is a small island between Britain and Ireland, in the Irish Sea. Other countries nearby are France, Belgium and the Netherlands. See the maps below.
The Irish sea is located to the east of Ireland between Ireland and Britain. See the map at the link below.
The Isle of Man lies between Britain and Ireland.
No tunnel, country or bridge connects Ireland and the United Kingdom, so most goods need to cross the Irish Sea by commercial boats, ferries or large container ships.
Irish Sea, English Channel, North Sea, Saint George's Channel, North Channel, Atlantic Sea, and the Norwegian Sea.
The Irish Sea.
The Irish Sea lies between Britain and Ireland. However, Northern Ireland is part of the United Kingdom, therefore the UK shares a border with the Republic of Ireland and is not separated by the sea.
The Irish Sea and the Celtic Sea.
There are two. The Irish Sea and the Celtic Sea.
The Irish Sea lies between England and Ireland. It would not be described as a strait as it is too wide.
The island of Ireland (although not bordering the North Sea), which is split between the United Kingdom and the Republic of Ireland.
The Irish Sea and the Celtic Sea.
The Irish Sea separates Ireland and Britain.
The only country to border the United Kingdom is the Republic of Ireland, the rest of the country is surrounded by the sea.
The United Kingdom is not an island nation. The United Kingdom consists of the island of Britain and Northern Ireland, which is part of the island of Ireland. The United Kingdom does have a lot of sea ports and so that is a major element of its trade.
The Irish Sea and the Celtic Sea lie between Britain and Ireland, not a river.
Northern Ireland is part of the United Kingdom and on the island of Ireland. You can travel from the Republic of Ireland by driving across the border. The rest of the United Kingdom is across the Irish Sea, so you would travel by boat or plane to get to England, Scotland or Wales from Ireland.
