The nearest country is France, which is 20 miles away and from which Britain is separated by the English Channel.

Scotland is in the north, while Wales is in the west. Ireland, which is also an island, lies off the west coast of Britain. It consists of Northern Ireland and the Irish Republic.

The capital city is London, which is situated in south-east England.　　The UK has a total area of about 244,100 square kilometres (94,248 square miles).

The northern and western regions of Britain, that is Scotland and Wales, are mainly mountainous and hilly. Parts of the north-west and centre of England also consist of mountains and hills.　　Britain has a generally mild and temperate climate. It is, however, subject to frequent changes. It has an average annual rainfall of about 120 centimetres (47 inches).　　In 1998 the population of the United Kingdom was nearly 59 million. The density of population was approximately 240 people per square kilometre. However, in England, where 83% of the population live, the density was much higher, about 363 per square kilometre.　　In the UK, English is the first language of the vast majority of people.

In Scotland only a small number of people speak Gaelic.　　In Britain about 66% of the population say that they are Christian, while fewer than 5% say that they belong to other religions.　　Summary:　　Britain is an island that 　1　the Atlantic Ocean and the North Sea.
