What 3 things affect the size of a wave?
The size of a wave depends on three factors: the distance over which the wind blows across open water (the fetch), the strength of the wind, and the duration that the wind blows.
The larger these factors, the larger are the waves..
What are the two types of waves?
Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.
Is every 13th wave bigger?
It is not true that every 13th wave is larger than the others, as claimed in the film. In fact, there exists no pattern in wave sizes. In the original Kon-Tiki documentary, it was shown that the crew simply waited for a wave big enough to carry them over the reef.
What causes waves to be bigger?
Waves located on the ocean’s surface are commonly caused by wind transferring its energy to the water, and big waves, or swells, can travel over long distances. A wave’s size depends on wind speed, wind duration, and the area over which the wind is blowing (the fetch).
How many waves are in a set?
What are wave sets? A wave set is a group of three to ten large waves that seemingly appears out of nowhere and disappears just as quickly. Not only does the number and height of waves in each set vary, so does the length of time between sets. Sometimes it’s 5 minutes, sometimes it’s 25.
How high can waves get?
An earthquake followed by a landslide in 1958 in Alaska’s Lituya Bay generated a wave 100 feet high, the tallest tsunami ever documented. When the wave ran ashore, it snapped trees 1,700 feet upslope. Five deaths were recorded, but property damage was minimal because there were few cities or towns nearby.

What is the largest tidal wave ever recorded?
1720 feetA tsunami with a record run-up height of 1720 feet occurred in Lituya Bay, Alaska. On the night of July 9, 1958, an earthquake along the Fairweather Fault in the Alaska Panhandle loosened about 40 million cubic yards (30.6 million cubic meters) of rock high above the northeastern shore of Lituya Bay.
Can you swim under a tsunami?
The answer is NO, so that is NO number three. Toby Dewhurst explains it well, ie the tsunami goes all the way to the bottom so you can’t get underneath it. I used to body surf and you can dive under normal waves, but you cannot go under tsunami.
What is the biggest tsunami of all time?
Lituya BayAn earthquake followed by a landslide in 1958 in Alaska’s Lituya Bay generated a wave 100 feet high, the tallest tsunami ever documented. When the wave ran ashore, it snapped trees 1,700 feet upslope. Five deaths were recorded, but property damage was minimal because there were few cities or towns nearby.
What causes wave?
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. … The gravitational pull of the sun and moon on the earth also causes waves.
How far inland would a 1000 Ft tsunami go?
Tsunami waves can continously flood or inundate low lying coastal areas for hours. Flooding can extend inland by 300 meters (~1000 feet) or more, covering large expanses of land with water and debris. Tsunami inundation is the horizontal, inland penetration of waves from the shoreline.
What is the roughest ocean?
Southern OceanThe Southern Ocean, also known as the Antarctic Ocean or the Austral Ocean, circles round Antarctica and comprises the southern-most parts of the world’s oceans. This is known to be the roughest ocean amongst all the other oceans.
What is the roughest sea?
The roughest seas in the world are in the Drake Passage between Cape Horn and the Antarctic Peninsula. It is the one place in the world where the wind (and the water) can travel all around the Earth without interruption.
Do waves come in sets of 3?
Wave measurements usually show a tendency for large waves to group together–often referred to by scientists as “groupiness.” Normally, the number of waves in a group range anywhere from three to 15 or more, and it typically consists of smaller waves in the lead, larger waves in the middle and smaller waves again at …
Why do waves come in sets of 3?
A. Wave sets or groups occur when waves traveling at different speeds interact, making every few waves larger than the others. A common example is a fast-moving swell that interacts with a locally generated wave. The swell may not be very large in deep water but gets larger as it reaches shallow water.
What three factors affect the size and strength of waves?
The size of a wave depends on three factors: the distance over which the wind blows across open water (the fetch), the strength of the wind, and the duration that the wind blows. The larger these factors, the larger are the waves.
Is every 7th wave bigger?
So the first wave in a group is tiny, the next one is bigger and so on until you get the biggest one in the middle of the group. Then they get smaller again. The last one is tiny, so the biggest wave in the group is in the middle, and if there are 14 waves in a group, the seventh wave is the biggest.
