This here is a nice and lovely map of Asia. Note that the teardrop-shaped Tibetan Plateau dominates the map, and we have India to thank. For the last 50 million years, it has been pushing upwards, merging into the main continent. Wherever it touched, the greatest mountain ranges rose up. Not just the Himalayas, mind you, but others like the Hindu Kush, the Karakoram, Jinping, to name a few.
But does the shoving of India to Asia influence the rest of the continent's geography? Would the mountain ranges of Turkeye, Iran, Mongolia, China and Siberia exist without India joining Asia, let alone be as big as they are today?
