How waves are generated in ocean? and why even big lakes do not have waves?Is it due to vastness of sea?

Question

We are told that the waves are generated due to
1. Earth's Rotation 2. Moon's Gravitational force
Then, all this should make waves even in ponds or lakes. Is it that due to it's very small amplitude and frequency that we do not see or feel them physically?

Answer 1

Waves are born as the air pressure on the surface changes and the frictional drag of the moving air against the water creates ripples. Once a ripple has formed, there is a steep side against which the wind can press directly. Now the energy can be transferred from air to water more effectively and the small waves grow rapidly.

The wave size will depend on the wind velocity, the time the wind blows and the vastness of action.

In a pond you do not have the vastness effect so waves will be smaller than in the ocean. Very big lakes may have big waves but no as big as in an ocean.

Answer 2

Actually, waves are due to the Sun's energy, not #1 or #2. The Sun sends energy our way in the form of light and radiation. The light powers the atmospheric circulation patterns and these patterns create wind and storms. The wind over the ocean creates a drag over the surface of the ocean, and this friction causes slight waves. These surface waves create oceanic circulation, however they also travel and accumulate over the surface. The speed of the wind has an effect on the wave's speed and size, and also the duration of the blowing wind. This is why there are large waves that wash up on the beach during a storm, and smaller waves when there's not much atmospheric activity.
There are waves on lakes and even rivers if they are large enough. Plus, if there is a landslide or something, waves will occur.

Answer 3

Tides are caused by gravitational forces. Waves are caused primarily by wind. Waves can form on any standing body of water, even a puddle in your backyard. But waves have more of a chance to build to greater size when they are exposed to stronger winds, and when they have the chance to be exposed to those winds for a longer period of time. Just look at the size of the waves that come ashore during a hurricane. There hasn't been any change in gravity, just a major change in wind force and duration. A wave on a small pond will reach the shore before it has the chance to reach great size, even if the wind is strong. But on the ocean the winds are often more powerful than inland, and the wind can act on a wave over a distance of many miles, causing it to gradually attain great size.

Answer 4

Waves are simply a disturbance in water. When you see a wave the water is not moving from side to side, it is just a vibration that is moving through the water. Think of wiggiling a jump rope, you see a wave but the material of the jump rope is not actualy moving from side to side. Now a wave is different from a current. The current is near the shore when you see the waves crash, the stuff surfers surf on. That is caused by the vibrations in the water hitting something (the shore) making a big old wave. Pond vs. Ocean maybe there just isnt enough vibrations in a pond.

Answer 5

Big lakes do have waves. Small lakes do have waves. Have u ever been to a lake before???

Answer 6

I think this is linked to wind but I'm not sure

maybe streams like the gulf stream or stuff like that influences
