Describe the positive and negative effects of tides?

Answer»

The positive effects of tides are as follows:

  • The tides clear the waste and hence the coasts become clean.
  • Ports do not get filled with sediments.
  • Ships can move up to the ports during high tide.
  • During high tide, sea water can be stored in salt pans from which salt can be obtained.
  • The tidal force can be used to generate electricity.
  • With the high tide, fish move into the creeks and this helps fishing activity.
  • The tides help in maintaining the mangroves and the coastal biodiversity.

The negative effects of tides are as follows:

  • A lack of an understanding of the timings of high and low tides may cause accidents to swimmers entering the sea.
