Question

Which of the following statements are correct?

• A. High tides help ships navigate in shallow harbours.
• B. Tidal energy cannot be used to generate electricity.
• C. Ships navigate through shallow harbours only during low tide.
• D. Fishes may be found closer to the shore during a period of high tide.

Answer 1

Answer: (A), (D)

The correct options are
A High tides help ships navigate in shallow harbours.
D Fishes may be found closer to the shore during a period of high tide.

During a period of high tide, water levels close to the shores are raised. This allows for ships to arrive at and leave shallow harbours easily.

Fishes may be found closer to the shore during high tide. This gives fishermen plenty more to catch.

Additionally, the rise and fall of water due to tides is being used to generate electricity in some places.
