Explanation: A tidal port is a harbor whose water level is significantly affected by the rise and fall of the tide. The tidal influence can affect the depth of the harbor, which in turn impacts the ability of ships to enter and leave the port. Tidal ports are common in coastal areas where the tidal range is substantial, and they require careful management to ensure safe navigation.
Kandla, also known as Mundra, is a major port located in the state of Gujarat, India. It is situated on the Gulf of Kutch, which is part of the Arabian Sea. Kandla is a tidal port, and its water level changes with the tides. This tidal influence is a defining characteristic of Kandla, making it a prime example of a tidal port in Gujarat.
The tidal nature of Kandla means that the port's depth varies throughout the day, which can affect the types of ships that can use the port and the times at which they can enter and leave. This tidal influence is managed through careful scheduling and the use of dredging to maintain the required depth for larger vessels.
In contrast, Paradwip is a port located in the state of Odisha, not Gujarat. It is a deep-water port and is not influenced by tidal changes to the extent that Kandla is. Similarly, Marmagao is a port located in the state of Goa, not Gujarat. It is a natural harbor and is not a tidal port.
Understanding the geographical and tidal characteristics of ports is crucial for students studying geography and for those preparing for competitive exams such as the UPSC and GPSC. It is important to recognize the specific features of each port and the state in which it is located to avoid common misconceptions and to accurately identify tidal ports in different regions.
In summary, Kandla is the correct answer as it is a tidal port located in Gujarat, while Paradwip and Marmagao are located in different states and do not share the same tidal characteristics.
