Question

Define ‘the theory of plate tectonics’. How has their movement resulted in the formation of Himalayas? Explain.100 word

Answer 1

The theory of plate tectonics states that the lithosphere or the solid upper layer of the earth consists of many distinct plates, which float over asthenosphere or the uppermost layer of the earth’s mantle.


These huge plates that are known as tectonic plates or crustal plates move sideways occasionally, causing earthquakes.

Thus, the floating plates below the continents are much thicker and comprise of Sialic rocks; while the plates under the oceans are much thinner and made of Simatic rocks.

It is believed that several landforms, including the entire Himalayan range are formed due to the movements of these plates.

Answer 2

Plate tectonics  is a systematic theory representing the large-scale movement of seven big plates and the actions of a substantial number of miniature plates of the Earth's lithosphere.

The Himalayas are perceived as the young fold ranges. Ironically the worlds highest hill ranges are all young encounters i.e., developed in contemporary geological point measure (10- 25 million years) eg. The Himalayas. While old hills are superficial mountains with compressed lengths due to consecutive corrosion since times in the geological timescale. For instance, 200 million years ago such as Urals and  Aravallis.

In short, Development of Himalayas is essentially the consequence of plate tectonics. As per serving tectonic system different type of landforms patterns emerging from plate concentration or divergence in plate margins. Fold mountains are the outgrowth of convergent plate margin of 2 continental plates forming Synclines and Anticlines.
