Tides occur due to underwater volcanic activities.

Tides are the periodic rise and fall of sea levels.

Tides are the rhythmic rise and fall of ocean levels.

Tides result from the gravitational interaction between the Earth, moon, and sun.

Waves are generated by the wind blowing over the sea surface.

Waves are the horizontal movement of ocean water.

Waves are formed due to the movement of energy through water.

Waves are the movement of water due to underwater earthquakes.

Waves are periodical movements in water, indicated by an alternate rise and fall of the surface water. In alternative words, waves are literally the energy, that moves across the ocean surface. The height of the wave is decided by the strength of the wind.Waves travel as the wind pushes the water along its course while gravity pulls the crests of the waves downward. The falling water forces the former troughs upward, and hence the wave moves to a new position. The actual motion of the water under the waves is circular.
