Why are India Pakistan and other countries known as subcontinents?

India, Pakistan, and surrounding countries are referred to as a subcontinent due to their distinct geological, cultural, and historical characteristics that set them apart from the rest of Asia. The term reflects the large landmass that is geographically separated from the rest of the continent by natural features like the Himalayas to the north and the Indian ocean to the south. Additionally, the region has a unique blend of languages, religions, and ethnicities, contributing to its identity as a subcontinent. This concept emphasizes both the physical size and the rich diversity of the area.
