why the sea never comes out from its boundry usually.?

Gravity...or if you mean why doesn't it come over the land...then that is because the land is higher then the sea, hence there is not enough water in the sea to raise it above the land.

in the unconstrained case (no floor), water from the lowest hole will reach the furtherest given enough time (vertical space to drop). With a vertical constraint (a floor), the optimal coverage will be from a hole one third the way up from the floor, not the top hole near the surface of the water, and not a hole at floor level.\n\nAlthough I really don't see how this applies to wind sailing:-)

Why does it always spiral the same direction?\n\nIt *doesn't*.\n\nTry the experiment in your bathtub.  It can go either way.\n\nSome people mentioned the "coriolis effect", but for\nsomething as small as a bathtub, this effect is *tiny*.\n\nThe last references below describes experiments where (with\nvery careful controls) this effect was demonstrated, but\nfor most of our experiences, we're seeing other local\neffects (ie. residual currents in the water).  The\nexperimenters literally had to let the water sit for *days*\nin order to let the residual currents die down so that they\nwouldn't overwhelm the vanishingly small coriolis effect.\n\n[By the way, the coriolis effect is *not* vanishingly\nsmall for something *really big* -- like a weather\nsystem.  In that situation, there is a significant\ndifference in the speed (due to the earth's rotation)\nof the portion farthest from the equator vs. the \nportion closest to the equator.]

good one... like there is Tsunami...a low pressure area in water body.Why there is no air movement.\nThere may be a little movement which is not highly noticeable.

It is partly a matter of scale, and partly because of local relief in the landscape. \n If you were to stand on a perfectly flat plain or on the surface of an ocean, the farthest point you could see would be approximately 30 miles distant.  \n Also, because of changes in elevation over smaller distances, and/or obstructions to our field of vision, we tend to see even smaller 'chunks' of curvature, which our brains interpret to be flat.

Ok.. listen.. you have to think about this one a little bit\n\nIF everytime a lighting hit the water, everything got electrocuted, then there would be no fish in the sea.. so people that said that are not thinking right.. \n\nnow.. how far do you have to be\nLighting will try to reach ground right? thats the way it works? so it will find the fastest way down.. now Im going out on a limb here, but salt water conducts electricity pretty damn well.. probably better than a human body.. so my guess is, lightning will go straight down into the ocean floor.. \n\nnow.. this doesnt mean you wont die if its near you, because some electric current might choose a different path, but I would say if you are outside of 100 meters you would be ok. But I would get out of the water when a big storm is coming.. not because of lightning, but because the waves might be too strong to swim in

because the earth are moving around the sun so thats y..its never disappear.

Higher latitude...\n\n...altitude is something else.\n\nIt has to do with the seas, and the winds. Check the following link for information:

probably gravity. it's the most likely. without gravity there would be no wind, running water or sea waves. think about it for a second it'll make sense

Maybe it has something to do with grounding. If a ship is in the ocean and not touch anything then there is no reason for the current to go up right?

the surrounding area that is hit is temporaily electrified (no more than a second or so) this is due to the fact that the sheer size of the ocean, and the fact that water dicipates electricity so quickly.  There really isn't any thing out of the ordinary cept the poor fish that was caught in the affected area might be floating.

In the South Atlantic there is a vast area for waves to develop, and much energy, as well as thousands of miles of  fetch, unbroken by land, for them to build. The southern oceans are known for their tremendous waves. The latitudes of the 50's and 60's south  are known for their wild waters(the roaring 50's)

Some rivers dont they can finish in a lake thats inland. Water just flows downhill till its at the lowest level it can find which is usually the sea

Well, generaly, a large fish is bound to only swim in the ocean because there is enough space for it. Also it depends if the fish lives in salt water versus fresh water.

Because of scaling, corrosion, and sediment problems.  The dissolved solids in seawater tend to cause excessive problems.  \n\nIf there is any evaporation taking place, the water vapor leaves behind all of the dissolved solids, and scaling and corrosion can occur even where there is no evaporation.

It is downhill from start to mouth using sea level. However, there are rivers that do flow uphill at times. The continental divide is the reason for it. All water flows Easterly East of the continental divide. All water will flow Westerly West of the continental divide. I've been there and seen it, weird. \n\nAnother explanation would be the rotation of the earth. The water would be "pulled" toward the equator, where the largest mass of the earth's body would be.

If you are refering to those real small islands at the north end, they are off limits because they go under water at high tide.  There is nothing on them for you to see because of this.
