Why ripples are formimg in water?

if you drop something in the water, it displaces water, and that displaced water moves other water, the rock going down in teh water pushes some up, which then pushes some down, and so on and so on.

When water falls, it becomes a mist. Then light refraction occurs and the wave length changes. It looks white because it scatters the light. I also creates rainbows because of the light refraction.

They will remain suspended above the waterline due to surface tension unless you.......\n\n   (see below)

There are natural surfactants in the water from certain organisms that grow in the ocean (e.g. kelp, coral). The wave action on the water and surfactants then makes the foam.

Waves are normally created by wind!\n\nAdditionally, just like the earth, even the moon has gravity... Its the moon's gravity that pulls the sea water towards it, and "creates" waves!

waves don't always come to shore, they go in most every direction, the reason you see them close to shore is the sloping land under the water makes it apper to get bigger and more pronouced, as it nears the shore. thus making it seem like they always come to the shore.

Water and impurities in the water cause friction.

Yes, it does. For one thing, I've seen it hit the ocean and cause a scatter/ripple effect in the water. It was actually very cool.\n\nSecondly, why do you think people always tell you to get out of the water when there is a lightening storm overhead?

It is not air that takes a spherical shape in water but rather the water forces it to take that shape. This is because of surface tension - the same reason why drops of water tend to be shperical. It is the state with least potential energy implying the most stable state.\nIn case of smoke in air, the same thing does not happen as neither air nor smoke does not have any surface tension (being gases, rather mixtures of gases, they are not cohesive unlike water or any liquid for that matter). The simply diffuse into each other randomly (and aided by air currents) however, smoke being a hot mixture of gases, tends to rise higher, hence the wierd upgoing patterns formed by smoke.

Because settling only works if there is no chemical reation involved. All of the prticals of some substances will not settle out of water. like sugar. Even if they do the time frame needed to accomplish this is to long.

Water often contains a great deal of suspended air - but it is not visable as they are very small.  When you shake the water, the little bubbles start bumping into each other, and if they are big enough, you will see them.  If they are big enough to see, they will float to the top and pop!\n\nIf you have an aerator on your kitchen sink you can get lots of bubbles from shaking water.  Water that has sat in a bottle undisturbed for a while has most of its bubbles gone.

Seems to me like an accumulation of thousands of (young) fish, encountering plancton(food).\nOtherwise, it could have been the rising/falling tide, causing a whirlpool-like motion in the waters, which occur only once at that very same spot during the rise or fall of the tide, because of the constant changing water level. At falling tide, for example, if the water has to pass through a formation of rocks that are still submerged and invisible, the waters on the surface start to move noticeably, and if the trapped water body is large, it may create a scary scenario, which is indeed seriously dangerous for any swimmers caught in it.

because the sound reverberates in your skull, and with the water acting as a sound proofing, there is very little distraction noise-wise and the whispering becomes clear.  Basically you are hearing from the inside out.  Now when you come out of the water, there is water in your ears, and you no longer have the insulation of the water around your head.  That, combined with the noise of sitting up, the water splashing around you, the ambient noise from your surroundings, causes you to not recieve the soundwaves, which are now outside of your head and "mixing" with the rest of the noise.\n\nGet it?

Generally, small angular waves are an indication that something in the water is moving just below the surface and can be attributed to some form of water organism.  This can range from water bugs to minnows to fish or whales.  \n\nEven in very small puddles I have seen very small water beetles.  It usually takes about two to three days for them to begin to appear.\n\nIf you want to perform an experiment to see if the "currents" are created by water based organisms or not try filling a small wading pool with a few inches of water and covering it with a tarpaulin or some other cover for about two weeks.  At the same time fill a second small wading pool with water of a few inches depth and leave it uncovered for the same time period.  After two weeks have gone by you should begin to see the "currents" you asked about.  If you take the cover off the "control" pool and look you should not see these same "currents".  (Just be sure that there are no winds or breezes when you are performing your observations.)\n\nDave Cooke

Pools of water that form near the ocean due to shallow dips in the landscape. When the tide goes out the water is trapped in these small pools. When the tide is in they are just another part of the ocean.

I heard on the Discovery channel the other day that there are spots in the ocean where bubbles come up from the bottom of the ocean and it decreases the density of the water so boats sink.  The bermuda Triangle is said to have these "spots"  http://dsc.discovery.com/convergence/bermudatriangle/bermudatriangle.html   go there

Totally false.  Waves do occur in ponds and lakes.\n\nIn fact, any really experienced sailor can tell you that when the wind is blowing strongly, shallow waters are more dangerous thaan deep ociean waters.\n\nFifty foot waves can and do occur in the Great Lakes.  Many ships, boats, and lives have been lost, especially during November.\n\nThe big waves in the Great Lakes come crashing ashore, against piers, and against the shoreline ice barrier that forms during winter.\n\nThey are as spectacular as many typical ocean waves, but it is true that you can get even bigger waves from the ocean, such as the ones used by surfers in Hawaii.
