1.The Highland Zone
This zone is characterised by rocky, rugged hills and eroded mountain faces, interrupted by valleys and extensive plains. Because these higher lying areas get less sunlight during the day and more rainfall than the lower lying areas, they are generally colder and unsuitable for farming.
The Pennine Mountain Range, Cumbrian Mountains and the mountains of the Lake District are included in the Highland Zone. Some of these mountains peak at an impressive 3000 feet (or 914 metres) above sea level. Devon and Cornwall are situated on a peninsula that is part of the Highland Zone, and is particularly rugged and bare.
