Main Body
formation of tide
1. High tide and low tide

90° from high tide, low tide occurs due to compensation of water.
2. Spring tide
when sun & moon act in coordination.
Tide exacerbate
3. Nip Tide
when sun & moon are at right angle.
Difference between tides and waves
Tides | Waves
> Occurs twice a day | > Always
> Originate due to gravitational force | > Originate due to slope of continent and wind (advancing/receding - when receding is slow waves enlarge)
> can be source of renewable energy at large scale | > At small scale
Conclusion
Tides and waves are major geophysical phenomenon on earth.
