The British Isles can be divided into two, not only because of its geography but also because of its climate and agriculture.(32)If you draw a line from about the Bristol Channel to the Wash .then to the south of this line there are mainly low lands and hills, and to the north there are higher lands and mountains. This includes the Pennines, which is a range of mountains that runs north to south, and is known as the backbone of England. It is wetter in the north because of the higher land, and drier and sunnier in the south. This has an effect on the agriculture, of course. To the north there are sheep and cows because the grass grows so well, and(33)to the south there are arable farms growing crops and cereal.
    The South West of England is famous for its beautiful countryside and dramatic coastline. One particular area of natural beauty is Dartmoor, which is inhabited by wild ponies. The countryside in the South East is more gentle, and there is a lot of fruit-growing.(34)It is also the most heavily populated part of Britain. Wales is characterized by its mountains in the north and its valleys in the south. Scotland is famous for its lakes, of course, known as lochs. The moors and mountains are beautiful and empty.(35)Ireland is famed for its rains and its rich green grass, its romance and its mists.
