Three Seas Surrounding the Indian Peninsula: Arabian Sea, Bay of Bengal, Indian Ocean

The Indian Peninsula (south of the Indo-Gangetic Plain) is bounded by three major water bodies:

• Arabian Sea – to the west; connects to Persian Gulf, Red Sea; key for trade with Middle East, Africa, Europe.
• Bay of Bengal – to the east; receives Ganges-Brahmaputra; cyclone-prone; trade with Southeast Asia.
• Indian Ocean – to the south; opens to the Southern Ocean; strategic maritime domain.

These seas define India's maritime climate (monsoons), economy (ports, fisheries, hydrocarbons), and geopolitics (Indian Ocean Rim). The peninsula's tip at Kanyakumari marks the confluence of all three.
