How long will last the earth's tides?

Obviously English is not your first language, but you make yourself perfectly understood - ignore people like Zinger.\n\nThe Earth's tides are caused by a combination of the moon's gravity and the gravitational effects of our own orbit around the sun, so I would imagine that we will have tides for as long as the moon and sun are around.

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

From what i understand the earth will eventually leave the earth system altogether in a few hundred thousand years, this process is not however do to tidal drag. That force is responsible for slowing the rotation of the earth (and other planets) What most people don't understand is that the moon acts as a stabilizer for the earth. they degree of axial tilt would vary wildly. the equator may wind up as the north pole and go back again. planets without moons all experience this extreme wobble effect.

I  am very concerned about global Warming, The east coast could be underwater and the northpole could be gone in as little as 50 years. Today's choices could have a dramatic effect on the future. yet NOTHING is being done :(.

Yes, the first part is true.  Why does that make tides more "believable"?  \n Any two gravitaionally-bound objects will orbit around a common center of gravity.  (which is closer to the more massive object).

The Earth would lose sea tides and other water tides.  This would mean the sea receding in some parts of the world and flooding in other parts.  I also think that the Earth will "wobble" on its axis and its path of revolution around the sun would change.  That would mean change in the duration of the day and the year, I guess that would mean toal destruction.

Good question!\n\nIn fact, causing the tide on Earth actually results in the Earth-Moon system losing a little energy during every orbit.  \n\nThis results in the moon moving a little further from the earth to maintain the angular momentum of the system.

it sounds like you're talking about global warming. it's very likely that the oceans will rise significantly and that the coastline of all the continents and islands is gonna change considerably. the latest I've heard is not 3' in the next 30 years but maybe 1'.

lunar activity couses the tides with the gravitational pull

googled to find this:\n\n"The Moon, at first, will recede further and further from the Earth, but the two bodies will continue to orbit about their common centre of gravity. Around 600,000,000 years from now, the Moon will be too far away for total eclipses to occur.\n\nHowever, this process won't continue indefinitely - as Mike Sawicki points out in his Myths About Tides and Gravity:\n\nOnce the Earth becomes tidally locked with the Moon, the solar tides will tend to slow the Earth’s rotation even more, so the day will be longer than the month and the Moon will rise in the West and set in the East. The water spheroid generated by the Sun will cause the high tide to appear earlier than the time of highest moon ... Then the tidal force of Earth on the Moon will pull the Moon into a lower orbit and eventually inside the Roche limit (18500 km), whereupon the Moon will disintegrate producing a ring round the Earth."\n\nWhatever happens, we won't be around to know!

The obvious answer is the tides would be much smaller. We would still have tides, but they would be: (1) Caused by the Sun and therefore smaller. (2) They would come at roughly the same time each day.\n\nThis would affect a good deal of the marine life that depends on the tidal changes.\n\nLighting would also change. Reproductive behaviors in a number of animals are goverened by the moon's cycle. It is not known how much the moon's absence would change this.\n\nThe days would not grow longer as someone suggested. The opposite is true as the friction overcome in producing the tides takes energy. That energy is coming out of the earth's rotation and the moon's orbiting around the earth. The moon is slowly moving farther away and the earth is slowing down so the days are getting longer. Of course, this is an extremely slow process and you are not going to notice any change. The moon's absence would mean it wouldn't take place.\n\nEarthquakes would not be affected. They are caused by plate tectonics, which is independent of the moon.\n\nIf you are interested in the moon, try\nhttp://groups.yahoo.com/group/lunar-observing/\n\nHope this helps\n\nChuck

Tides occur because the gravitational force between two bodies decreases with distance. Gravitation is the universal force of attraction between all matter. It holds astronomical bodies together and attracts different bodies toward each other. Because gravity tugs on nearby things more strongly than on distant things, the oceans closest to the Moon, feel the greatest attraction to the Moon. Being fluid, these nearby oceans move upward in response to the Moon's pull, until there is a balance between the upward force from the Moon and the downward force from Earth. The high tide on the far side of the Earth occurs because these most distant oceans feel the least attraction to the Moon. In essence, they are left behind as the Moon pulls the other parts of Earth toward itself with greater force.\n\nThe Moon is steadily moving up. As anyone who climbs long flights of stairs knows, it takes energy to move up. If the Moon is moving up, where does the energy come from? There is only one place it could come from: the spin of Earth. This is a zero-sum game that physicists call the conservation of angular momentum: The total angular momentum in the Earth-Moon system, which related to the energy stored in both rotation and revolution, must remain the same. Since the Moon is gaining angular momentum as it spirals away, Earth must lose the same amount of angular momentum. Earth loses angular momentum because the high tide closest to the Moon is trying to get back directly underneath the Moon, while the high tide farthest from the Moon is trying to get as far away from the Moon as possible. Consequently, the high tides flow westward, and in so doing, they encounter continents and islands. The water pushes against these landmasses, which, because of rotation, are moving eastward. The net result is that the westward motion of the tides -- slowing down the rotation, retards the eastward revolution. The day is getting longer by about 0.002 seconds per century. It does not sound like much, but over billions of years, it adds up.\n\nOn a moonless Earth, the only tides would be from the Sun. The Sun accounts for one-third of the tides on Earth today. Therefore, Earth would still experience some tides and its rotation would still slow down, but not nearly by as much as nonce. A moonless Earth day would be around eight hours long at this time in its life, 4.6 billion years after it formed.\n\nAdditionally, the faster a planet rotates, the faster its winds blow. Higher winds and the shorter days on Earth would have major effects on evolution; imagine what day-to-day life would be like with only three or four hours of sunlight each day, much different than now…\n\nLess protection from meteors and imminent impacts, as you can see, the Moon has shielded us from a cosmic bombardment, just look at its surface.

Predictions suggest that the range will increase until the Earth and Moon become double synchronised, that is, both are tidally locked to one another. The Earth-Moon distance would then be about 550000km. This won't occur for something like 50 billion years. Before then, though, our Sun will have died, and both the Earth and Moon almost certainly won't even exist.\n\nThis website for answer confirmation and more info  -->http://www.madsci.org/posts/archives/apr2002/1020171327.As.r.html\n\nGod is spelled B-I-G B-A-N-G\nPBrax@netscape.com

No tides (not true) \nNo intertidal zone (not true) \nNo eclipses \nDarker skies for astronomy \nSome animals affected (such as salmon and turtles) \nDifferent night creatures \nNo gravity (not true) \nMore impacts on Earth by space debris \nNo lunar calendar \nNo lunar phases \nWorse surfing \nDarker nights \nDifferent name for "lunatics'' \nNo lunar fables (werewolves and so on) \nNo nearby place for astronauts to go \nA lost vehicle for romance \nA lost theme for love songs \nNo Man in the Moon \nThe day would be eight hours long. \nThe winds would be much stronger.\nhttp://www.astrosociety.org/education/publications/tnl/33/33.html\n\nFYI \nThe Moon is moving away from the earth which is why the question is in theory with scientists..The Moon is receding at 2 inches per year\n\nAs for your unintelligent insult on which you are trying to be supreme, you have no CLUE...\n\nIn 1897 George Darwin, son of Charles, suggested that tides are causing the Moon to spiral AWAY FROM US. His hypothesis was CONFIRMED in 1969 after the Apollo 12 astronauts placed corner reflectors (like the red and orange ones on a car) on the Moon. By firing lasers from Earth to the Moon, off the corner reflectors, and back again, astronomers measured the round-trip time and, hence, the distance to the Moon. Repeating the experiment over several years, they confirmed Darwin's prediction. The Moon is receding at 2 inches per year.\n\nSo instead of trying to sound politically correct find facts to the basis of your answer DORK..\nSo here is an explaination of why our days would be 8 hrs long.Earth loses angular momentum because the high tide closest to the Moon is trying to get back directly underneath the Moon, while the high tide farthest from the Moon is trying to get as far away from the Moon as possible. Consequently, the high tides flow westward, and in so doing, they encounter continents and islands. The water pushes against these land masses, which, because of rotation, are moving eastward. The net result is that the eastward rotation is retarded by the westward motion of the tides -- slowing down the rotation. The day is getting longer by about 0.002 seconds per century. It doesn't sound like much, but over billions of years it adds up. Not that you would understand..\n\nNone of your previous questions have been intelligent..
