Why is India considered as a subcontinent? Elaborate your answer.

A subcontinent is a large, relatively self-contained landmass which, though part of a continent, possesses a distinct geographical identity of its own. India, with its neighbours, forms the Indian subcontinent within Asia.

Why India qualifies as a subcontinent

• Tectonic distinctiveness: the landmass rides on the separate Indian Plate, which broke away from Gondwanaland, drifted north and collided with the Eurasian Plate to raise the Himalayas — it is geologically set apart from the rest of Asia.
• Natural barriers: the Himalaya–Karakoram–Hindu Kush arc, the Sulaiman–Kirthar ranges and the Purvanchal hills wall it off in the north, while the Arabian Sea, Bay of Bengal and Indian Ocean bound it in the south.
• Distinct climatic regime: the region functions as one monsoon unit, with the seasonal reversal of winds governing its agriculture, festivals and economy.
• Continental scale and diversity: it packs lofty mountains, the Indo-Gangetic plains, the peninsular plateau, the Thar desert, long coasts and islands, drained by great rivers such as the Indus, Ganga and Brahmaputra.
• Human mosaic: multiple language families (Indo-Aryan, Dravidian, Austro-Asiatic, Tibeto-Burman), all major world religions and diverse ethnic groups share a common civilisational thread.

Since India, Pakistan, Bangladesh, Nepal, Bhutan, Sri Lanka and the Maldives together display this self-contained physical and cultural personality, the region — with India at its core — is aptly called a subcontinent.
