Identify the sea-port in India on the basis of the given characteristics : 1. It is more than a century old port on the west coast of India. 2. It is a natural harbour protected by a breakwater and also by a mole. 3. A deep draft channel of about 14 metres depth permits large vessels to enter the harbour. Select the correct sea-port from the options given below :
- A.Mormugao Port
- B.Deendayal Port
- C.Cochin Port
- D.Jawaharlal Nehru Port
Correct answer
Explanation
The correct answer is A, Mormugao Port. Mormugao in Goa, a natural harbour at the mouth of the Zuari estuary, was opened in the late nineteenth century and is sheltered by a breakwater-cum-mole, which fits every clue. The Portuguese developed the port, and its first berths came up in the 1880s, so it is well over a century old. It became one of India's major ports in 1963, after Goa joined India. Its approach channel, dredged to about 14 metres, lets large bulk carriers in, and it has long been India's leading port for exporting iron ore from the mines of Goa and Karnataka. Option B is wrong because Deendayal Port at Kandla in Gujarat is a tidal port built in the 1950s to make up for the loss of Karachi at Partition. Option C is wrong because Kochi's modern port took shape only in the 1920s and 1930s, when a channel was dredged through the sand bar into the backwaters. Option D is wrong because Jawaharlal Nehru Port at Nhava Sheva was opened only in 1989. Exam tip: Mormugao: Goa, Zuari estuary, iron ore exports.
