Recent studies show that India is still moving northwards at the rate of 5cm/year and crashing into the rest of Asia, thereby constantly increasing the height of Himalayas.
Evidence to prove that the Himalayas are still rising:
1. Fossil formation found in Shivalik hills:
Similar fossils have also been found in the Tibet Plateau. This indicates that in the past, Tibetan plateau and Shivalik hills shared a common location, similar level and thus similar vegetation, life etc.; then Tibetan plateau got uplifted.
2. Desiccation of lakes of Tibet:
In the Tibet plateau, we find deposits which are generally found in lakes. This indicates that lakes once existed in Tibet but because of upliftment the water got discharged and deposits remained.
3. Frequent Earthquakes
4. Youthful nature of rivers (High erosion, v-shaped valleys etc.)
The North-South Division of the Himalayas
The Himalayas consist of a series of parallel mountain ranges:
The Greater Himalayan range, which includes:
The Great Himalayas(Himadri), and
The Trans-Himalayan range
The Lesser Himalayas (or Himachal), and
The Outer Himalayas (or Shiwalik).
