INDIAN GEOGRAPHY

Detailed explanation-1: -About 20 mm per year of the India-Asia convergence is absorbed by thrusting along the Himalaya southern front. This leads to the Himalayas rising by about 5 mm per year, making them geologically active.

Detailed explanation-2: -The Himalayan mountain range and the Tibetan plateau were formed as the Indian tectonic plate collided into the Eurasian plate about 50 million years ago. The process continues even today, which causes the height of the mountain range to rise a tiny amount every year.

Detailed explanation-3: -The Himalayas are still rising by more than 1 cm per year as India continues to move northwards into Asia, which explains the occurrence of shallow focus earthquakes in the region today.

Detailed explanation-4: -The collision between the two continental plates is still happening today. India continues to creep north by 5cm (2in) a year, causing Everest to grow by about 4mm (0.16in) per year (although other parts of the Himalayas are rising at around 10mm per year.

Detailed explanation-5: -The Indian Peninsula drifted towards the north and finally collided with the much larger Eurasian Plate. As a result of this collision, the sedimentary rocks which were accumulated in the geosynclines (known as Tethys) got folded and formed the mountain systems of the West Asia and Himalayas.
