Main Body

As per latest NOAA (USA), tides are the periodic rise and fall in the levels of ocean water due to combined gravitational influence of Sun, Moon and Earth.

Formation of Tide:

Tides are formed based on the relative Gravitational pull of Earth moon and the ocean water.

Types of Tide:

[Box containing diagram showing]

Based on frequency:

Based m frequency
During semi-: During I / I -> Near / Full moon tide
During spring: Near Full moon

Waves vs Tides comparison table in text form.

1In Full Moon Tide, ocean birth dim & moon are in the same: in the same line, the gravitational pull is added and longer tides are seen.
2In Neap tides, moon is perpendicular to the sun-earth axis, hence the tidal bulge is smaller than full moon tide.

[Comparison table: Tides vs Waves]

Tides:

1Large quantity of water is vertically displaced.
2Movement of water from depth to upwards buoyancy number.
3Help in docking of ships at shipyards.
4Seen at coastal boundaries.
5Gravitational force propels Tides.

Waves:

1Movement of ocean water by orbital motion creation.
2No large movement of water from depth.
3Influence movement of ships based on direction of movement.
4Seen both at coasts and in open oceans.
5Multiple forces like Tsunami using inscription, etc wind etc

Hence, both Tides and Tidal waves possess energy which could be harnessed as sources of renewable energy (Tidal energy-12 GW potential, wave energy-41 GW potential).

Therefore, Deep Ocean Mining and Project Samudrayaan are also in right direction to basically leverage various priorities of oceans for sustainable development.
