what are the two impartance of tides and waves
Answers
Answer: The importance of tides are:
1. They can cause a change in landforms of the Earth. While they can destroy coastlines, they also help in the formation of creeks and inlets.
2. Strong tides help in the building of lower flood plains of rivers. These are very fertile.
3. Since the debris is swept away by tides, they help to keep the harbours clean.
4. In cold countries, tides bring in salt water to the shore and their continuous movement prevents the harbour from becoming ice bound.
5. The low lying areas of the sea coast during high tides trap water which is used for the manufacturing of salt. In India, along the west coast, salt is manufactured in this manner.
6. The alternate rise and fall of the tides help the fisherman to sail out and return back to the coast with the tides.
7. Tidal energy is fast becoming an important non conventional source of energy. They are used in the production of electricity along the Gulf of Kutch and in the state of Gujarat.
IMPORTANCE OF OCEAN WAVES
Ocean waves are very important for weather forecasting and climate modelling as well as for coastal communities, shipping routes and offshore industry.
2. Recent studies of coupling atmosphere-ocean-wave models have shown improvements in the simulation of North Atlantic sea surface temperatures in climate models.
3. Ocean waves are thought to play a role in weather forecasting such as improving hurricane intensity forecasts by regulating surface friction. 4. Adding an ocean wave component to the ‘next generation’ of climate and weather models will provide an opportunity to address long standing biases.
5. Extreme ocean waves continue to be a threat for coastal communities and the offshore industry. How ocean waves will change in the future will be of great interest to decision makers for coastal communities, shipping routes and the offshore industry.

Answer:
Tidal Energy
Two high tides and two low tides occur during every 24-hour period. The predictability of the tides, fast movement of water during the inflow and outflow can provide a source of renewable energy to communities living along the coast.
