Which phenomenon helped in the formation of the Himalayas?

In Journey to the End of the Earth, the author explains that the collision of the Indian subcontinent with the Asian landmass led to the formation of the Himalayas. This geological phenomenon, known as continental drift, occurred after the breakup of the ancient supercontinent Gondwana. As tectonic plates shifted and collided, the land was forced upward, giving rise to the Himalayas. This event illustrates the powerful and dynamic nature of Earth’s crust, and it connects Antarctica’s history to the geological evolution that shaped various landscapes and ecosystems worldwide.
