The term "Pennine" refers to a mountain range in northern England, known as the Pennines. This range stretches approximately 250 miles from Northumberland in the north to Derbyshire in the south. The Pennines are often called the "backbone of England" due to their central location and significant impact on the region's geography and climate. The Pennines are characterized by rugged terrain, deep valleys, and scenic landscapes, making them a popular destination for outdoor activities such as hiking and cycling. The area is also home to several national parks, including Yorkshire Dales and Peak District, which showcase the natural beauty and biodiversity of the region.
