Origin and Rise of The Himalayas: “Chilling” Facts!
Posted on: April 18, 2018. Comments ( 1 )

225 million years ago…
The six continents that we know today, exists as one massive landmass—the supercontinent Pangaea, which formed a third of the Earth’s surface—surrounded by a gigantic ocean called Panthalassa.

Off the Australian coastisa large island, today known as India.

A vast ocean called Tethys Sea separates this large island from what is today the continent of Asia.

200 million years ago…

The “rolling of the Earth’s Mantle” makes the tectonic plates to move across the Earth’s surface and thereby breaks Pangaea into two landmasses, Laurasia and Gondwanaland.

This large island, which is today India, begins to drift in a northerly direction.

100 million years ago…

Laurasia and Gondwanalandbreak up into the six geographical continentsthat we know today: Africa, Antarctica, Australia/Oceania, Asia-Europe “supercontinent Eurasia”, North America, and South America.

80 million years ago…

The large island, which is today India, continues to drift northward at a speed of 9cm/year, coming approximately 6,400 kilometres south of the continent of Asia.

40-50 million years ago…

The Eurasian and Indian continental tectonic plates bump into each other—the vast ocean, the Tethys Sea, goes under and vanishes. India impacts what is today the continent of Asia, nearly halving the speed of its northerly progress, andthe uplift of the Himalayas is initiated.

The rapid uplift of the Himalayan young fold mountainsis a direct consequence of this collision and the speed of tectonic plate movement—the Indian continental plate, drifting northwards—subsequently drops and halves to around 4-6 cm/year.

The ocean floor of the Tethys Sea is not completely pushed under the converging tectonic plates—thick sediments of the ocean floor on the Indian margin of the ocean is heaped onto the Eurasian continent, creating the Himalayan mountain range.

Today…

The Himalayas, world’s highest mountain range and “roof of the world”, is a northwest-to-southeast-running arc thatstretches across India, Pakistan, China, and Nepal over a length of 2,400 kilometres. The Himalayan mountain system comprises two, nearly-parallel ranges separated for their entire length by a valley of an average width of 250 kilometres.

Mount Everest, the world’s highest mountain by peak elevation, stands at 8,848 meters. In fact, the Himalayas isthe world’s only mountain range to boast severalpeaks over 8,000 meters tall—the runner-up is the Andes in South America, whose tallest peak is just 6,962 meters tall.

    An audiovisual reference depicting the above theory would make it easier for the youngsters to understand.Please share the link if you can.
    Overall very interesting article.
