What Causes Tides To Be Much Higher At Many Seaports Than At Sea

Moon causes low tides and high tides.?

From a physics perspective, yes it does affect our bodies. However, the earth has such a strong effect on us and we are so small that any effect the moon has is nearly zero. Even if there was no earth, the moon would have a small effect on us. The moon is much smaller than many planets, and we are small ourselves. The effects of gravity are easily seen between large bodies than when comparing big to small. The ocean is a large component of earth and its difference in density from the rest of the planet allows the moon's gravitational effects to be seen.

High Tide and Low tide?

Answer

The high and low tide are caused by the gravitational forces between the earth and the moon. However, the source of the real effect takes some explaining to grasp. The incorrect way of thinking is that the moon attracts all the water to itself, therefore causing a high tide on the side of earth close to the moon, and a low tide on the side far from the moon. However, if this was the case, there would be a high tide once per day. But there are TWO high tides a day. The reason is, the part of the earth both AWAY from the moon, and CLOSE to the moon BOTH get high tides...

Now we need to explain why this is so. The earth and moon rotate around each other, each pulling the other towards itself. The moon attracts every piece of matter on earth. Since gravity is inversely proportional to the square of the distance, this force is greater on the side of the earth closer to the moon, and lesser on the side of the earth further from the moon. Since the earth is quite a rigid object, this difference in forces fails to deform the earth (much). However, it succeeds quite well in deforming the oceans -- which are not as rigid. Since the waters on the moon side are attracted more strongly than average, they tend to bulge TOWARDS the moon, hence causing a high tide. The waters on the opposite side of the moon, since they are attracted less strongly than average, tend to 'lag behind' the rigid earth, and bulge AWAY from the moon, which in this case, is also AWAY from the earth, again, causing a high tide. Low tide occurs at about right angles to the moon, where the force on the waters match the average pull of the moon on the earth closely.

The question that usually follows this is, why doesn't the sun cause any tides (comparable to that of the moon) although its pull on the earth is larger? The answer is, although the gravitational pull of the sun on the earth is larger than that of the moon, due to the much greater distance, the force changes very little from one end of the earth to the other. Since it is the difference in the force than the average magnitude of the force that matters for creating tides, the net effect is much less than that for the moon.


:o) come on.. i'm almost at level 3!!hope that answered your question!

Would an especially high low tide ever be higher than a very low high tide, at the same spot?

By definition if a "high low tide" becomes higher than a "low high tide" it becomes the new "high tide low", so it sometimes happens, but is renamed if it ever does, so intersection does happen , but it causes this to be renamed so it is not a permanent state, of affairs...just momentary.

The best places to watch the tides are the bay of Fundy in Canada, and the river Teste in England, ( at Southhampton ), where the difference in tidal highs and lows is clear, by a distance of about thirty feet and twenty feet respectively, and both have a tidal race, that causes the tide to go out , and in, at a rate that can NOT be outrun by a man on foot,( it is like watching a bath empty itself ), in the bay of Fundy the tide comes in over flat lands, and can actually be seen covering this flatland at this rate, it also traps many tourists, often fatally, as they never seem to think that this bay can be covered completely in so short a space of time, it is several miles square, and is covered, as if a bedsheet is thrown over a bed, a hover craft is the choice of rescue vessel, for the life services/police, in this area, if you ever visit, I recommend that you heed this warning, it may be some sight to see, but you do not want to join the statistics for those who do not listen to the warnings !.....if you really have to know, how fast this tide comes in, I suggest that you get a washing up bowl, and fill it with water, then hold it over your kitchen floor and while moving your arms, tip it all out , throwing it across the floor, that is how fast it comes in !

How do low and high tide occurs?

by gravitational attraction to the moon

Why was world war 2 so long? what caused it to be so long?

there is not any particular reason, yet there are factors. earlier to WWII, Italy joined the best chum element throughout WW1 in hopes of having new land. regrettably for italy, the U.S, France, and super Britain rather plenty disregarded Italy in the process the treaty of Versailles. Italy replaced into very unhappy, pondering it lost many adult men. So on the spark of WW2, Italy replaced into torn. initially it joined the allys, yet saved switching to what it theory replaced into the prevailing element. in a protracted time, it desperate to combat for the axis by way of fact Germany promised Italy territory if it fights with them. Japan replaced into diverse. in fact, it needed land, by and super interior the South eastern Asia. Japan in this time replaced into exceptionally industrialized and extremely city. It mandatory many "products"n to gasoline its industries. To get those products, they had to commerce with the different u . s .. whilst WW2 sparked, the Japan observed this as an danger to snatch China and the different islands. The U.S., an best chum to China, ordered this to provide up. whilst Japan refused, the U.S. desperate to provide up oil paying for and advertising to Japan. Oil replaced into mandatory to Japan's industry. particularly of a negotiation, Japan desperate to bomb Pearl Harbor, subsequently getting into U.S. into the conflict.
