Model Answer
Harnessing Tidal Energy:
Floodgate dams are built across inlets. During high tide, water flows into the inlet and gets trapped when the gate is closed. After the tide falls outside the floodgate, the trapped water flows back to the sea through a pipe, passing through a power-generating turbine to produce electricity.
Ideal Regions in India:
- Gulf of Khambhat (Gujarat)
- Gulf of Kuchchh (Gujarat)
- Gangetic delta in Sunderbans region (West Bengal)

Explanation
- The question has two parts — the mechanism (2 marks) and the locations (1 mark). Balance your answer accordingly.
- Use the exact textbook terms: floodgate dam, high tide, turbine — examiners look for these keywords.
- All three locations must be named for full marks on the location part. Do not confuse Gulf of Khambhat with Gulf of Kuchchh — both are separate answers.
- Avoid writing a general definition of tidal energy; focus on the process as described in the textbook.
