What factors influence the size of a wave quizlet?
What factors influence the size of a wave? The strength of the wind, the length of time it blows, and the distance the wind blows.
What influences the size and energy of a wave?
Size and energy of waves The greater the wind speed, the greater the wave height, the greater the wave energy. The longer the duration of the wind, the larger the wave height and thus the greater the wave energy.
What three factors determine the height of a wave quizlet?
Wave heights increase as all three factors increase: The greater the wind speed, the larger the wave heights. The longer the duration, the larger the wave heights. The longer the fetch, the larger the wave heights.
What factors of wind determine the size of a wave quizlet?
The factors that determine the size of a wave are…? wind speed, fetch, and the length of the time the wind blows.
What factors affect the speed of ocean waves?
The speed of a wave is dependant on four factors: wavelength, frequency, medium, and temperature.
What are the three things that causes waves?
Waves are dependent on three major factors – wind speed, wind time and wind distance.
What factors determine the height length and period of wave quizlet?
What are the primary factors that determine wave height? Wind speed, length of time wind blows in one direction, and fetch. If you have two deep-water waves with periods of 5 and 10 seconds, what can you say about their speeds? The longer period wave will have greater speed.
Which of the following three 3 factors affect the growth of wind waves?
Three factors affect the growth of wind waves. Wind must be moving faster than the wave crests for energy transfer from air to sea to continue, so the mean speed of the wind, or wind strength, is clearly important to wind wave development. A second factor is the length of time the wind blows, or wind duration.
What four factors determine the formation of a wave?
Waves form as a result of the water's motion, gravitational forces, and winds. The most common waves we see are created by wind. However other waves include those created by gravitational forces (e.g. tidal waves) and those created by underwater disturbances, such as earthquakes (e.g. tsunamis).
How do you know if the waves will be big?
Check the "swell rating" to see how big the waves are. The rating is a number that estimates the height of the waves from one to five, with five stars being the biggest. The next thing to do is to check a swell period. That is how long the waves will be rolling in, which tells you what kind of break it may suit.
How does wind speed affect wave size?
The greater the wind velocity, the longer the fetch, and the greater duration the wind blows, then the more energy is converted to waves and the bigger the waves. However, if wind speed is slow, the resulting waves will be small, regardless of the fetch or duration.
How do you get the largest waves?

What three things do you need to get big waves?
How big wind waves get depends on three things:
- Wind strength. The wind must be moving faster than the wave crests for energy to be transferred.
- Wind duration. Strong wind that does not blow for a long period will not generate large waves.
- Fetch.
What causes large ocean waves?
Waves are most commonly caused by wind. 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 3 causes of waves?
Waves are dependent on three major factors – wind speed, wind time and wind distance.
Which condition creates the largest waves?
Ideal Wave Formation Conditions
- Wind Speed – The greater the wind speed the larger the wave.
- Wind Duration -The longer the wind blows the larger the wave.
- Fetch – The greater the area the wind affects the larger the wave.
What determines the size of ocean waves?
Wave height is affected by wind speed, wind duration (or how long the wind blows), and fetch, which is the distance over water that the wind blows in a single direction. If wind speed is slow, only small waves result, regardless of wind duration or fetch.
HOW period affects wave size?
The wave energy below the surface of the ocean is pushed upward causing the waves to increase in height. The longer the period, the more energy under the surface, which is why longer period waves grow bigger than short period waves.
How do waves get bigger?
When wind blows, it transfers the energy through friction. The faster the wind, the longer it blows, or the farther it can blow uninterrupted, the bigger the waves. Therefore, a wave's size depends on wind speed, wind duration, and the area over which the wind is blowing (the fetch).
What makes some waves bigger than others?
Surface Waves The faster the wind, the longer it blows, or the farther it can blow uninterrupted, the bigger the waves. Therefore, a wave's size depends on wind speed, wind duration, and the area over which the wind is blowing (the fetch).
How does swell affect waves?
These general rules include the shorter the swell period, the weaker the waves and the longer the swell period, the more powerful the waves. This makes sense, as motion creates motion. Swell period is important because it can determine if there are good waves or not.
How does swell affect wave height?
Long-period swells accumulate energy, travel faster, and can easily cope with local winds and currents, resulting in larger surf when it comes to average wave height. Forerunners are the first waves coming in on long-period swells.
Why do waves get bigger and smaller?
Waves are a product of the wind. When the wind blows over a large surface of open ocean water, it creates ripples. The size and extent of a ripple depend on the wind speed, the distance it blows across the water, and the length of time the wind blows.
What causes large waves in the ocean?
Waves are most commonly caused by wind. 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 causes big swell?
As wind blows across the water's surface, friction occurs and energy is transferred from wind to water. The result is a rising crest that forms into a wave. Over time and distance, sustained wind strength and duration build up a large amount of energy beneath the ocean's surface, forming deeper waves known as swells.
What happens to a wave if the amplitude increases?
This means that a doubling of the amplitude of a wave is indicative of a quadrupling of the energy transported by the wave. A tripling of the amplitude of a wave is indicative of a nine-fold increase in the amount of energy transported by the wave.
Why do the waves get bigger?
Now, a new study suggests the biggest waves there—already the world's largest—are getting bigger, thanks to faster winds attributed to climate change.
What causes waves to be higher?
Adverse weather or natural events often produce larger and potentially hazardous waves. Severe storms moving inland often create a storm surge, a long wave caused by high winds and a continued low pressure area.
