What Causes Waves in Ocean? Which Types of Waves are produced in Ocean?

Do you know, what causes ocean waves? Actually sun, wind, and waves are associated with maritime travel. You are awakened in the morning and soothed to sleep at night by the sound of the waves crashing on the beach. On these, surfers ride. Kids enjoy playing in them. They are dived under by swimmers. Why do waves occur or what causes waves in ocean? Ultimately, the sun and wind. Uneven solar heating affects our globe. As we approach the poles, it becomes less intense and is strongest close to the equator. Have you ever thought how wind is produced! Wind is a result of the unequal heat. As hot air rises, it pulls in colder air to fill the void. This temperature difference is what generates wind. Energy can come from the wind. Some of the energy is transferred to the water when it blows over it. Surface water particles move as a result of this energy. However, they don’t only move in the direction of the wind. Instead, they loop around. On the surface, a water molecule rises. It slows down when it approaches the highest point (the crest). After that, gravity takes over and pulls it back down. As it travels, it makes a circle that returns it to the initial point or a location relatively near it.

This sensation is familiar to anyone who has ever stood in a wave. As the wave crests, the water pushes you upward. Then you fall into the dip (low point between waves). You’re pushed both forward and backward. Your body would make a circle if you were small enough to float in the ocean. Watch a buoy bobbing in the ocean the next time you see one. You can proceed in a circle after it. We get big swells when wind generates waves in deep sea. Waves on the beach don’t resemble swells at all. They appear more like rolling hills. We only notice a wave’s characteristic shape when such surges reach shallow places. The circular water flow catches on the seafloor as it enters it, slowing it down. The water behind it builds up as a result of this. It eventually becomes unwieldy. As the wave reaches its peak, it tumbles over on itself. Before retreating, it slides up the beach after crashing onto the sand.

Unlike waves created by the wind, not all waves crest on the shore. Storm surges may result from large storms. Long waves known as tsunamis can be produced by underwater earthquakes or mudslides. Tsunamis and storm waves come ashore like a wall of water, obliterating everything in their path. Severe weather, such a hurricane, can produce waves with a greater potential for danger. Storm surge is a series of lengthy waves that are generated far from shore in deeper water and grow in strength as they approach land due to the intense winds and pressure from this sort of severe storm.

Underwater events like earthquakes, landslides, or volcanic eruptions that swiftly move vast volumes of water can also produce dangerous waves. The term “tsunami” refers to these enormous waves. You don’t typically picture waves like storm surge and tsunamis washing up on the shore. These waves can go far inland and roll onto the shore like a significant sea level rise. Waves are also produced by the gravitational pull of sun or moon on the earth. These waves, often known as tidal waves, are tides. A common misunderstanding is that a tidal wave and a tsunami are the same thing. Tsunamis can happen in any tidal state and have no connection to tide information at all.

Summarizing the Types of Waves

Speed of a wave: The depth of the water a wave travels in and its wavelength—the space between two succeeding waves—determine how quickly it goes. Longer waves often go through the sea more quickly. Although wind-driven surface waves are the most frequent, there are other types of waves that can be found at sea. Every different type of wave has different reason of production.

What causes waves in ocean?

As mentioned earlier that different types of waves are created by different reasons. This explains what causes waves in ocean (which will be different in every case).

Tidal Waves: Tidal waves develop when the moon, rather than the wind, pulls on the surface of ocean. Yes, our planet’s surface is indeed pulled toward the moon by its gravity. Although both land and water are affected by this gravitational attraction, the more pliable water is the one that is affected more. Depending on which side of the Earth you are on, several types of tidal waves can form. You will experience rising water levels that creep inland up the beach (high tide) while your region is directly facing the moon since the waters will be bulging moonward. But because they are effectively being drawn inward into the core of the earth, sea levels will decline and shrink away from the beach when your region is the furthest from the moon (low tide).

Why Pacific Ocean is called Ring of Fire?

Tsunamis: Although they are commonly confused, tidal waves and tsunamis are not the same. Although they behave like tidal waves and travel inland and upshore, they are mostly brought on by undersea earthquakes. The Pacific Ocean, the world’s most seismically active ocean basin, experiences two tsunamis on average each year.

Storm Surge: Storm surge is the result of a hurricane’s winds moving across a sea surface and progressively displacing water in front of it. Water has “piled up” into a dome several hundred miles wide and tens of feet high by the time the storm is close to the coast. Then, as the ocean swell approaches land, it floods the coastline and erodes beaches.
