what creates waves in the ocean?

Answer 1

The movement of the water caused by wind and the tug of the moon's gravity on the water itself.

Answer 2

A whole range of things.

The most obvious causes which probably have the greatest effect are wind and the gravitational pull of the moon and sun.

Then there are seismic movements and processes which take place both under water and to a lesser extent on land such as earthquakes, volcanic activity, rock falls and so on-the tsunami which occurred in the far east a few years ago shows the effect these processes can have.

Water currents criss-cross the oceans at different depths and where they interact waves may well be formed.

When waves strike a solid object they rebound causing other waves and so on.

Answer 3

The wind does create most of the waves in the ocean. Normal wind driven waves are mostly no larger a couple of meters. Waves that are created and driven by storms can be very large. Large storm systems with low pressure cause the ocean to well up underneath them and the wind, since it's both a higher velocity and more concentrated, will whip up higher waves. These waves can be several stories high, some mariners have reported waves of 25ft or higher. Storm surge caused by hurricanes and tides are not "waves". Storm surge from hurricanes is when water is pushed out in front of the hurricane; the surge builds up higher as the hurricane strenthens and the longer a hurricane lasts. Tides are the mass movement around the ocean basins caused by the gravitational force of the moon. Tsunamis are giant waves caused by off-shore or near off-shore very large earthquakes, which physically displace the entire water column from ocean floor to surface and build up as the wave moves closer to the shore. If you would like to test the "wind causes waves", fill up your bathtub and plug your hairdryer up close by (don't drop it in the water!!!). Turn the dryer onto low speed and put it above the water on one end of the tub and let the dryer run for several minutes. The longer you let it run, the more waves should be created. If you turn the dryer on high, the waves will get larger.

Answer 4

A wave is a disturbance that propagates through space or spacetime, transferring energy and momentum and sometimes angular momentum. While a mechanical wave exists in a medium (which on deformation is capable of producing elastic restoring forces),

Answer 5

The winds cause waves on the surface of the ocean (and on lakes). The wind transfers some of its energy to the water, through friction between the air molecules and the water molecules

Answer 6

generally, waves are created by energy transfer from wind. they can also be cause by an under sea earthquake which is called a tsunami.

Answer 7

I agree that the tides are primarily influenced by gravitational attraction of the moon (high tide/ low tide) , but also by currents (convection) based on temperature differences, prevailing winds (weater fronts), global rotation,etc.

Answer 8

wind causes waves, with the exception of tsunamis caused by earthquakes or large masses falling into the water.
the moons pull causes tides.

Answer 9

high tide and low tide depending on the moon position above our location

Answer 10

A mixture of gravity and wind
