following questions: The folds of the Great Himalayas are asymmetrical in nature. The core of this part of Himalayas is composed of granite. It is very perennially snowbound and a number of glaciers descend from this range. The range lying to the south of Himadri forms the most rugged mountain system and is known as Himachal or lesser Himalaya. The ranges are mainly composed of highly compressed and altered rocks. The altitude varies between 3,700 and 4,500 metres and the average width is of 50 km. while the Pir Panjal range forms the longest and the most important range, the Dhauladhar and the Mahabharat ranges are also prominent ones. This range consists of the famous valley of Kashmir ,the kangra and kullu valley in Himachal Pradesh. This region is well known for its hill stations. The outermost range of the Himalayas is called the Shiwaliks. They extend over a width of 10 to 50 kilometre and have an altitude varying between 900 and 1100 metres. These ranges are composed of unconsolidated sediments brought down by the rivers from the main Himalayan ranges located farther North. These valleys are covered with thick gravel and alluvium. The longitudinal valley lying between lesser Himalaya and the Shiwaliks are known as Duns. Dehra Dun ,Kotli Dun and Patli Dun are some of the well known Duns.

Physical Map of India
The Greater Himalayas or Himadri: The northern most range is known as the Great or Inner Himalayas or the ‘Himadri’. It is the most continuous range consisting of the loftiest peaks with an average height of 6,000 metres. It contains all the prominent Himalayan peaks. The folds of Great Himalayas are asymmetrical in nature. The core of this part of Himalayas is composed of granite. It is perennially snow bound, and a number of glaciers descend from this range.
The Lesser Himalaya or Himachal: The range lying to the south of the Himadri forms the most rugged mountain system and is known as Himachal or lesser Himalaya. The ranges are mainly composed of highly compressed and altered rocks. The altitude varies between 3,700 and 4,500 metres and the average width is of 50 Km. While the Pir Panjal range forms the longest and the most important range, the Dhaula Dhar and the Mahabharat ranges are also prominent ones. This range consists of the famous valley of Kashmir, the Kangra and Kullu Valley in Himachal Pradesh. This region is well known for its hill stations.

Explanation:
- The most distinctive features of the Himalayas are its towering elevations, steep jagged mountains, vast valleys and alpine glaciers, terrain severely affected by erosion, deep river canyons, complex geological structures, and A series of elevated belts with diverse ecological signs, Fauna and flora and climate.
- The mountains to the south of the Himachal Pradesh form the steepest mountain range, known as the Himachal or Lesser Himalayas. The altitude of this area is about 3700-4500 meters above sea level. Many popular summer resorts such as Shimla, Mussolini and Kulvalley are located in this area. The average diameter of this area is about 50 km. The Himachal Mountains are very rough and composed of compressed rocks.
- Other important mountain ranges in the Lesser Himalayas are the Peer panjal Mountains south of the Kashmir Valley and the Daoladar Mountains in Himachal Pradesh. The largest mountain range is the Peer Panjal Mountains. The Lesser Himalayas consist of the famous valleys of Himachal Pradesh: Kullu and the Kangra valleys.
