What would the Earth be like if we had more than 1 moon?

Since our moon doesn't cause storms but only the tides, there's no reason to believe that another moon would create havoc. In fact for another moon to exist, I'm sure it would have to me much much smaller than the one we have to remain in a stable orbit.

the tidings of the sea would stop existing, and basically everything containing water (including the human body) would OR die, OR very urgently have to adapt! Mmmm, no, we'd die. Even female menstruation depends on the moon...

Here is a very simple and precise explanation with good illustrations\nhttp://home.hiwaay.net/~krcool/Astro/moon/moonorange/

To answer your question in two parts,\n\n1. No, two moons would not cause an appreciable increase in the Earth's gravity.\n\n2. If gravity were higher than it is now on earth, people would be shorter, because the extra gravity would actually cause their cartiledge to compress a bit.\n\nAnd, as a fun side note, giants have been on Earth. Giantism is caused by a incorrectly fuctioning pituitary gland, which produces too much growth hormone. If you think it's fun to be a giant, think again: it hurts a lot, you have weak bones and muscles, and can mess up puberty. Very unpleasant.

i think the moon would be a refreshing change. yes.

i can tell u what would happen if we had no moon... this is the answer... \n\n\nIf the Moon did escape from Earth, the main effect would be the lack of tides on Earth. Tides are caused by the differential gravitational force on the equatorial regions: i.e. the region closer to the Moon experiences more gravitational force than the region on Earth away from the Moon. This results in the formation of high and low tides on different regions of the Earth. \n\nOther than tidal forces, there is no other geological or climatic influence of the Moon on Earth. There are issues like no more Moon to light up the night sky, no more solar eclipses, etc. but there will be no change in the geology or climate on Earth.

We don't have to explain it. Most stars are multiple, some are not. \nBy good fortune, we have a single star system which means we can have a solar system and stable orbits. The tidal forces would have been too strong from a multiple star system for planets to form. The single star system also allows for moons around the planets. Without our moon we probably would not have life on Earth in the first place, among other things.

It depends on how large the impactor was and how fast it was moving. A large impact would make a new and very large crater on the moon. A couple days later we would have a great meteor shower display here on earth as pieces impacted our atmosphere.\n\nIf it was large enough to shatter the moon you could end up with several large pieces orbiting separately. Again, it depends on the size and speed of the impactor. If you broke it up sufficiently, you could form a ring.\n\nThat brings us back to what would then happen on earth. 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-obse...\n\nHope this helps\n\nChuck

great question - I wish I knew more but tides would be different. Also - the day would be shorter. The equatorial regions would be hotter, and the regions further away would be colder. The earth's rotation would be more stable with less wobble.

I think it'll be a while yet before we see people being able to burrow and live under the moon's surface. Me personally? Well, I'd rather live *in* Uranus. Such a lovely place to visit when the weather is right.

yes it would affect the earth because it would disrupt our tides and all of our weather would either become very extreme or nonexistent also we wouldn't have a moon for any one else to visit and then we wouldn't be able to go to anywhere but the earth .

You can see about 4 miles to a flat horizon on the Earth. So from one horizon to the other would be 8 miles. (On the Moon, it would only be 3 miles-- the horizon is only a mile and a half away.)

Yes - the moon is far away, and the earth spins around it's own axis, creating day and night time. The moon would move a little 1/56 of phase shift during the half day it would take for the other half of earth to see the moon, but it's not noticeable.

Earth is rotating at a speed of about 1100 miles per hour. If our planet suddenly stopped rotating, the atmosphere would still be in motion at that speed. The atmosphere would be moving so fast it would literally sweep the land masses clear of anything not anchored to bedrock, this would mean rocks, soil, trees, buildings, people and animals. All would be swept up into the atmosphere.\n\nIf the Earth's rotation slowed down gradually over millions of years, and this is the most likely scenario, it would be a very different story. If the Earth slowed down to one rotation every year, called synchronous rotation, every area on Earth would be in either sunlight or darkness for one year. This would be similar to what the Moon goes through where for two weeks the front side of the Moon is illuminated by the Sun followed by the front side being in darkness for two weeks.\n\nBut what if the Earth stopped rotating completely? In that case, one half the Earth would be in daylight for half the year while the other side would be in darkness. The second half of the year it would be reversed. Temperature variations would be far more extreme then they are now. The temperature gradient would affect the wind circulation also. Air would move from the equator to the poles rather then in wind systems parallel to the equator as they are now.

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
