1. Himadri (Greater Himalayas)
- The Himadri is the tallest range, with an average elevation of 6,000 meters or more. Peaks like Mount Everest (8,848 m) and Kanchenjunga (8,586 m) are located here.
- Due to extreme cold, vegetation is sparse. Only mosses and lichens grow at higher altitudes, while alpine shrubs and grasses are found at lower elevations.
- Animals like snow leopards, Himalayan tahr, and yaks inhabit this region.

- This range is covered with dense forests of oak, pine, deodar, and rhododendron, making it rich in biodiversity.
- Animals like leopards, Himalayan black bears, and musk deer are found here.
- This range is home to picturesque valleys like the Kashmir Valley and Kullu Valley. Rivers like Beas and Ravi flow through this region.
- The Himachal range has several hill stations, such as Shimla, Manali, and Dharamshala, and fertile plateaus like the Chamba Plateau.
3. Shivalik (Outer Himalayas)
- One of the three parallel ranges of the Himalayas, the Shivalik range is the lowest, with an average elevation of 900 to 1,200 meters.
- It has tropical forests with sal, teak, and bamboo trees. This range is very fertile and lush.
- Animals like elephants, wild boars, and deer live here, along with various birds and reptiles.
