How do waves work?
Waves are created by energy passing through water, causing it to move in a circular motion. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.

What are the different parts of waves?
Vocabulary
- crest. the top of a wave.
- wave. moving swell on the surface of water.
- wave height. the distance between a wave’s trough and crest.
- wavelength. the distance between the crests of two waves.
- wave trough. the lowest part of a wave.
What are 4 parts of a wave?
Wave Crest: The highest part of a wave. Wave Trough: The lowest part of a wave. Wave Height: The vertical distance between the wave trough and the wave crest. Wave Length: The distance between two consecutive wave crests or between two consecutive wave troughs.
What is a group of waves called?
Swell dispersion and wave groups The dispersed arrival of swells, starting with the longest period, with a reduction in the peak wave period over time, can be used to calculate the distance at which swells were generated. The result is that wave groups (called sets by surfers) can have a large number of waves.
What is it called when a wave crashes?
Plunging waves are formed when the incoming swell hits a steep ocean floor or a sea bottom with sudden depth changes. As a result, the wave’s crest curls over and explodes on the trough. The air under the lip of the wave is compressed, and a crashing sound is often heard.
What is a very large wave called?
Although both are sea waves, a tsunami and a tidal wave are two different and unrelated phenomena. A tsunami is an ocean wave triggered by large earthquakes that occur near or under the ocean, volcanic eruptions, submarine landslides, or by onshore landslides in which large volumes of debris fall into the water.
What is the difference between a swell and a wave?
Waves are generated by wind moving over water; they indicate the speed of the wind in that area. Swell are waves (usually with smooth tops) that have moved beyond the area where they were generated.
What are swell waves?
Swell Wave Definition. Swell Wave Surface gravity waves on the ocean that are not growing or being sustained any longer by the wind.
What is a breaker in the ocean?
In fluid dynamics, a breaking wave or breaker is a wave whose amplitude reaches a critical level at which some process can suddenly start to occur that causes large amounts of wave energy to be transformed into turbulent kinetic energy.
