What are the effects of tides?

The effects of tides are:

1. Tides help to remove the debris from the seashore.
2. Strong tidal currents help ships to enter in shallow harbours, e.g., Kolkata
3. In certain harbours tidal basins are constructed to store tidal water, e.g., London harbour.
4. Tidal energy can be harnessed to generate electricity, e.g., UK and Australia.
5. Tides help in producing salt in the coastal area as water is collected/flooded by high tide in the low lying areas.
6. Tides govern the schedule of fishermen. They sail out and in with the tide.
7. In cold countries, tides prevent the ports from getting frozen as they keep coastal waters in constant motion.
8. Strong tidal waves help rivers in building their own flood plains, e.g., Thames in England.
9. The sea creatures which are attached to rocks depend on tides to bring their food along with the tidal waters.
