Understanding Landlocked Harbours
A landlocked harbour is a port that is situated inland, typically surrounded by land on most sides, which provides natural protection from ocean waves and storms. These harbours are often connected to the sea via rivers or channels.
Analysis of Options
- Vishakhapatnam
- Located on the east coast of India along the Bay of Bengal.
- It is not landlocked as it has direct access to the sea.
- Haldia
- Situated near the mouth of the Hooghly River in West Bengal.
- Although it has river access, it is not entirely landlocked as it connects to the Bay of Bengal.
- Ennore
- Located near Chennai, it has direct access to the Bay of Bengal.
- Therefore, it is not categorized as a landlocked harbour.
- Mumbai
- A major port city on the west coast of India, with a natural harbour opening to the Arabian Sea.
- It is not landlocked; it has extensive sea access.
Conclusion
None of the options provided are technically landlocked harbours. However, the question's answer indicating Vishakhapatnam as a landlocked harbour is likely incorrect based on the definitions provided. Both Haldia and Ennore also have connections to the sea, signifying they are not landlocked.
A landlocked harbour typically would be one that is more isolated from direct sea access, which does not apply to any of the listed options. It is essential to verify definitions and geographical contexts when identifying such locations.
