There's some confusion here, and some odd reality as well, which might be part of the source of the confusion. Our 'natural' impression of what's going on in many cases doesn't quite fit what's really going on in detail.\n\n1) Gravitational force doesn't exist 'on Earth'. You are aware of it, when you stand on something, only becuase you're standing on something, which is probably why the phrase 'on Earth' is used. The something is pushing back with a force equal to the force of attraction between you and the Earth. If you were to be falling free (as in skydiving, leaving aside air resistance, or in orbit on the Space Station), you would still be acted upon by the gravitational attractive force between you and the Earth, but you'd feel no such force. It's true the force diminishes (as the square of the distance between the bodies involved), but it still exists. And any body with the mass and size of the Earth will have the same gravitational attraction to you if you were near it (or on it) as the Earth.\n\n2) We can see such a force. Assorted satellites have orbited the Moon. Several folks have walked on the Moon (even hit a golf ball on the Moon) and, except that it's a smaller force (with the changes one would predict, including distance off the tee), the gravtational force of the Moon behaved just exactly as expected. The gravitational attraction of the Moon on you at the surface of the Earth is quite small (and easy to calculate) in comparison to that of the Earth. But in principle you are correct about its changing value. As you sit in your backyard (for 24 hours), and as the Moon orbits the Earth, you will indeed experience (but not really be aware of) the varying force between you and the Moon as it moves (and as the Earth rotates under it). Just as the Earth experiences changes in the direction of the gravitational attraction between itself and the Moon; but you are not so sloshy as sea water and so you don't actually feel (or diaplay) any tidal effects. And neither does the sea either feel its tides, I suppose. If you were quite close to a black hole, your height (and indeed your thickness) would be enough to experience very extreme tidal effects in a gravitational field of that intensity. Far worse than the high and fast tides in the Bay of Fundy in SE Canada, dramatic though they be. \n\n3) As long as the masses of the Earth and Moon remain the same, the gravitational force between them will be constant. The complication introduced by their motions about the common center of gravity in the two body system are mere complications. Hard to deal with mathematically, but mere complications none the less. \n\n4) There are thousands of planets in the Solar System, if your definition of planet is an independently orbiting chunk of stuff. On the other hand, there are only three planets (Jupiter, Saturn, Uranus) if you consider all the rest of those chunks (including the Earth) as merely trivial debris. Or some intermediate value if the orbit has to be primarily about the Sun, not another body. The Earth has one moon, Jupiter has lots (some largish), Mars has two (both smallish), ... Recently, the Hayden Planitarium in NYC revised an exhibit on the Solar System and demoted Pluto from planethood. With the expected storm of objection and discussion. And there have been found of late a couple of large, very distant, and very cold chunks rather farther out than Pluto. Are they planets? Or not? Jump in and join the arguement, it's pretty lively.\n\nAs for the claim that some 10th planet is really really magnetic and causing weather problems here... Magnets are rather hard to arrange in bulk form which is why so few materials have bulk magnetic properties; it requires alignment of the electrons at the atomic level across trillions of atoms, which is usually pretty haphazard and self cancelling. But even if a mountain could be made entirely magnetic (ie, no cancella

Come on, everybody, give this poor person a break! That's nasty, to suggest that the asker is stupid! \n\nThose who said it is because of gravity are basically right. The Earth pulls everything toward it. We pull the earth toward us, as well, but the earth is larger and pulls us harder. Do you ever watch the Moon in the sky as it goes around the earth? The moon drags the oceans back and forth. The moon is not big enough to drag the oceans away from the earth, because the earth is bigger and pulls them harder. So the oceans stay on earth. But the moon causes the tides to go back and forth. If you are interested in these thing, you can learn more about them by studying physics. Good luck!

Yes, the moon goes around the Earth at a much slower rate (28 days) than the Earth spins around once (24 hrs).\nClick on the link to the animation below. Notice how the Earth spins while the part of the moon facing us changes.

Assuming life on earth still existed and that water\ncould still be found (not all frozen), the tides \nwould be smaller, because the Moon influences the\ntides about 90% but the other 10% influence comes\nfrom the Sun's gravitational force... That's why\nthe tides are higher at New Moon and Full Moon, \nbecause both the Moon and Sun are pulling along\nthe same line, whereas at first quarter and last\nquarter Moon, the tides are relatively lower, \nsince the Sun and Moon's gravitation somewhat\ncancells each other out

if you check the tide tables printed for your area on the earth you will notice significant differences in the tides all year long. There are 2 lows and 2 highs per day every day, approximately ever 6 hours, alternating high, low, high low. The tide table lists these 4 for you. The lowest lows-highs are known to be during the NEW MOON, esp during winter, but full moons are quite low-high too. So, yes, the moon does exert gravitational pull on the earth and its waters.  \n\nFull moon even affects birth rate (labor), moods, crime. Eclipses are also notorious for its effects on people as well.\n\nTide changes vary from place to place on the earth.  Even a few miles north or south of the site a tide table is made for can affect the results predicted in the little tide booklet. The topography-geology of the bodies of water all over the world also affect this. Some places on the earth go thru MAJOR changes with the tides during these full and new moon phases every day.....Bay of Fundy is one place to look up......tidal change can by 30 feet. If there is a storm, then there is possiblity of even greater tide changes given in the tide tables.

The Moon does not play a key role in the universe.  In terms of the universe, the moon is not even noticeable.  It does not play a key role in our galaxy.  It does not play a key role in our solar system.  However, the Moon does have some profound effects upon Earth.\n\n1) Earth's oceans would have tides even if we did not have a moon.  The Sun is large enough that its gravity would create tides.  Oddly enough, the moon tides and sun tides are of almost equal size.  The Sun's gravity is more powerful than the Moon's gravity.  But the Sun is much farther so it balances out.  When the Moon and Sun are on the same side of Earth, the tides are much stronger.\n\n2) Most of the time, the Moon lights the night sky.  Without this light, it is doubtful that any of the nocturnal species would be nocturnal.  It is certain that the moonlight affected the course of evolution on Earth.

The moon, being much nearer to the earth than the sun, is the principal cause of tides. Because the force of gravity decreases with distance, the moon exerts a stronger gravitational pull on the side of the earth that is closer to it and a weaker pull on the side farther from it. The earth does not respond to this variation in strength because the planet is rigid—instead, it moves in response to the average of the moon’s gravitational attraction. The world’s oceans, however, are liquid and can flow in response to the variation in the moon’s pull. On the side of the earth facing the moon, the moon’s stronger pull makes water flow toward it, causing a dome of water to rise on the earth’s surface directly below the moon. On the side of the earth facing away from the moon, the moon’s pull on the oceans is weakest. The water’s inertia, or its tendency to keep traveling in the same direction, makes it want to fly off the earth instead of rotate with the planet. The moon’s weaker pull does not compensate as much for the water’s inertia on the far side, so another dome of water rises on this side of the earth. The dome of water directly beneath the moon is called direct tide, and the dome of water on the opposite side of the earth is called opposite tide.\n\nAs the earth rotates throughout the day, the domes of water remain aligned with the moon and travel around the globe. When a dome of water passes a place on the earth, that place experiences a rise in the level of the ocean water, known as high tide or high water. Between successive high tides the water level drops. The lowest water level reached between successive high tides is known as low tide or low water. Low and high tides alternate in a continuous cycle. The variations that naturally occur in the level between successive high tide and low tide are referred to as the range of tide. At most shores throughout the world, two high tides and two low tides occur every lunar day, the average length of a lunar day being 24 hours, 50 minutes, and 28 seconds. One of these high tides is caused by the direct-tide dome and the other by the opposite-tide dome. Two successive high tides or low tides are generally of about the same height. At various places outside the Atlantic Ocean, however, these heights vary considerably; this phenomenon, which is known as diurnal inequality, is not completely understood at the present time.\n\n© 1993-2003 Microsoft Corporation.

gravitational pull is different in different places on earth. but it is fixed. we cannot change it locally or globally. bcoz it depends on earth's mass, which we cant change.

Mass is a constant.  \n\nWeight depends on gravity.\n\nSo, your mass is the same on earth and on the moon,\nbut you would weigh one-sixth as much on the moon\nas you do here on earth.

The moon is often visible during the daytime! If it's not visible during the daytime where you are, it's visible from somewhere else on Earth.

The force of gravitational attraction that the earth exerts on the moon tending to pull the moon towards its center, is exactly balanced by the centrifugal force (that tends to take the moon away from the earth) on the moon due to its (approximately) uniform circular motion.\n\nMathematically,\n\nFg   =     Fc

The Earth is round.\nObviously at lower latitudes you view the moon from a different angle than what you would at higher latitudes.\nSo that at the equater the moon when rising would look like a bowl from that angle in that phase.

Ok, this is kind of a long answer, but bear with me.  First off, the night would be no darker than it currently is during a new moon.  Remember, the moon is only up at night half of the time.\n\nHowever, the consequences of Earth having no moon would be much more severe.  Life as we know it would probably die out.\n\nOur moon is actually fairly large compared to our planet...this is what causes the strong tides people experience living on the ocean.  This tidal force also causes a much more subtle effect known as "precession".\n\nEarth's seasons are entirely determined by it's "axial tilt", the amount that our axis of rotation is tipped to the axis of our orbit (it has absolutely nothing to do with Earth being closer or further form the Sun).  During summer in the northern hemisphere, that hemisphere is tipped towards the Sun, while the southern hemisphere is tipped away from the Sun...that's why it's winter there.\n\nNow, throughout its history, Earth has had a relatively steady 23.5 degree tilt, meaning that the seasons have always been roughly the same intensity.  As mentioned, the moon's tidal forces causes precession, meaning the rotation axis carves out a wobble 23.5 degrees in radius every 26,000 years.  It's kind of like a top spinning...not only does it spin quickly, but as it also slowly wobbles from the Earth gravity.  The direction of the rotation axis changes, but the magnitude of the angle doesn't change.\n\nSo, the moon has a steadying effect on our axial tilt...so what?  Well, without it, our axial tilt could vary a lot, being caused by changing tidal forces from Jupiter and the Sun.  There's good evidence to show that this is exactly what happened to Mars...it has no large moons, just a couple tiny captured asteroids which exert very little tidal force.   As a result, it seems that Mars has varied anywhere from 0 degrees axial tilt (no seasons) up to a 60 degree axial tilt (crazy intense seasons) caused by the tidal forces of the Sun and Jupiter.\n\nWith an axial tilt of 60 degrees, that means all locations northward of 30 degrees get 24 hours of sunshine in summer, and absolutely no sunshine in winter.  With such strong seasons, it's likely the oceans would evaporate off...this seems to be the case on Mars, where there is mounting evidence that there was once a large northern ocean that mysteriously disappeared.\n\nSo, Short Answer: The seasons will become incredibly intense, the oceans would evaporate off, and without liquid water, all life would die.

The moon's got gravity too, and like the Earth pulls the moon, the moon pulls on the Earth's waters. Depending on where the moon is, you get different tides. Kinda like if you move a magnet in a circle around a paperclip. The paperclip will move in different directions depending on where the magnet is.

When the moon is full, it is on the side of the Earth opposite the sun. It takes the moon about a month to go around the Earth once. So in the course of a single day, it remains in almost the same position.
