India: major ports & sea routes map study
Extend the port map outward: connect each Indian port to the sea lanes it serves.
STUDY NOTE 1
Gateways to lanes
Western ports face the Suez–Gulf lanes; eastern ports face Malacca and East Asia. India’s trade direction mirrors its two coasts.
STUDY NOTE 2
Draft and depth matter
Modern container ships need deep water; ports like Vizhinjam (deep natural draft) and JNPT grew because older harbours silted or stayed shallow.
STUDY NOTE 3
Sagarmala thinking
Port-led development links ports to coastal economic zones, inland waterways and rail — the sea-route map is really a supply-chain map.
Map reading task
Draw the two great lanes past India and assign three ports to each with their main cargo.

UPSC map practice & Geography Optional connection
For UPSC Prelims, pair the location with its state, neighbouring relief and relevant geographic process. For GS I and Geography Optional Indian geography revision, use a simple labelled sketch to explain the relationship rather than replacing the answer with place names. These are Pragnya-authored exercises, not official UPSC previous-year questions.
