How do the Himalayan mountains form a subcontinent?

The collision of the Indian Plate and the Eurasian Plate over millions of years led to the uplift of the Himalayan mountains. The Indian Plate pushing against the Eurasian Plate caused the Earth's crust to buckle and fold, creating the towering peaks of the Himalayas. This collision also contributed to the formation of the Indian subcontinent as the landmass was pushed northwards and separated from the larger Eurasian landmass.
