Most of England consists of low hills and plains, with upland and mountainous terrain in the north and west. Uplands in the north include the Pennines, an upland chain dividing east and west, the Lake District, containing the highest mountains in the country, the Cheviot Hills across the Anglo-Scottish border, and the North York Moors near the North Sea. Uplands in the west include Dartmoor and Exmoor in the south west and the Shropshire Hills near Wales. The approximate dividing line between terrain types is often indicated by the Tees-Exe line. To the south of that line, there are larger areas of flatter land, including East Anglia and the Fens, although hilly areas include the Cotswolds, the Chilterns, and the North and South Downs.
