Delhi Ridge

The Delhi ridge is an important part of the National Capital Territory (NCT) of the Metropolitan City of Delhi as it forms the extension of the northern side of one of the oldest and ancient Hill Ranges of India called the 'Aravalli Hill Ranges' dating some 1,500 million years ago which is even more ancient than the young 50 million years old Himalayas. The Ridge is also known as the 'Green Lungs' that shelters the capital city from the harsh Desert of Rajasthan from the western portion. A ridge is a geological feature that features a continuous elevational crest for some distance. Ridges are usually termed hills or mountains as well, depending on their size.
