The accepted theory about the formation of the Himalayas started to take shape in the year when German meteorologist Alfred Wegener developed his Theory of Continental Drift. According to Wegener, the earth was composed of several giant plates called tectonic plates. On these plates lie the continents and the oceans of the earth.
The continents were said to have formed a single mass at one point in time. We pick up the story about million years ago.
Around million years ago also known as the Middle Permian Periodan extensive sea stretched along the latitudinal area presently occupied by the Himalayas.
This sea was named the Tethys. Around this period, the super continent Pangea began to gradually split into different land masses and move apart in different directions. As a result, rivers from both the northern Eurasian land mass called Angara and the southern Indian land mass called Gondwana started depositing large amounts of sediments into the shallow sea that was the Tethys.
There were marine animals called ammonites living in the sea at the time. The two land masses, the Eurasian and the Indian sub-continent, moved closer and closer. Indian plate was moving north about at the rate of about 15 cm per year 6 inches per year.
The initial mountain building process started about seventy million years ago or the Upper Cretaceous period when the two land masses or plates began to collide with each other.
As a result, the already shallow seabed rapidly folded and was raised into longitudinal ridges and valleys. Soon afterwards, about 65 million years ago Upper Eocene Periodcame the second phase of mountain building. The bed of the Tethys started rising again. The sea retreated, and the seabed was elevated into high mountain ranges.
Later, about 25 million years ago Middle Miocene Period came another mountain building period, which led to the formation of the low Shivalik ranges.
After this, periodic mountain building phases occurred as the Indian plate pushed against the Eurasian plates, which led to the Himalayan ranges rising further.
The last major phase occurredyears ago. Although the phase of major upheaval of the Himalayas has passed, the Himalayas are still rising, albeit at a much slower rate.
Because of this reason the Himalayas are rising at the rate of about 5 millimetres per year. This means that the Himalayas are still geologically active and structurally unstable.
For this reason, earthquakes are a frequent occurrence in the entire Himalayan region. It has to be understood that it is impossible to detect the movement of the plates and uplifting of the Himalayas by casual observation.The width of the Himalayas varies from km in Kashmir to km in Arunachal Pradesh.
The total area of the Himalayan mountain region is nearly five lakh sq km. The Pamir, popularly known as the roof of the world is the connecting link between the Himalayas and the high ranges of Central Asia.
