With no gravity pull If the moon was to dissapear, what would happen to the world?

Question

Perhaps unimaginable, but if anyone has any suggestions...

Answer 1

All the tidal forces caused by the moon (in the sea, in the weather, etc) would change. This would change the climate all over the world, which would impact all life.

But life would adapt.

Answer 2

I assume you are getting rid of the moon, instead of all gravity.

It depends on how you get rid of the moon. If it magically disappears, then the Earth's orbit will change a little bit, because the Earth rotates around the Earth-Moon center of mass once each lunar month, and the velocity of that motion would perturb the Earth's orbit a little.

The moon is responsible for a bit more than half the size of the tides---the Sun does the rest. So the tides would be less than half their current size, and high tide would always be around noon and midnight.

In the long run, the day would stop getting longer. Also, the orientation of the Earth's rotation in space would become less stable, and so over hundreds of thousands of years the seasons on different parts of the Earth would become strange---there could be 6-month days and nights, like in the Arctic, over more of the Earth's surface, as the rotation axis moved toward the plane of the ecliptic.

Answer 3

The earth would spin much faster if there was no moon this would affect weather patterns, some speculate that great winds would ravage the earth. The lenght of day would be greatly reduced. The tides would cease our seas would become stagnant. Tidal rivers would be no more. The fish and all life within the vast oceans would die, without the aeration of the movement of the tides. Without the moon the earth no longer would tilt on its axis consequently the seasons would be greatly disrupted. As the climate and seasons changed food would be harder to grow, there could be huge disruptions to the growing seasons of plants and vegeatables. Animals and man would fight for survival, only the fittest could survive.

Answer 4

I guess we'd just have no moon? But on the same hand, if there wasn't any gravity pull, surely the Earth would stop orbiting around the sun too, because gravity pulls it in it's orbit. So therefore what would happen to the world is that it would probably be half hot and half frozen. Purely because where ever it stopped in orbit one side would face the sun, the other would not.
But if the gravity pull on just the moon stopped, then I would imagine that we'd just have a starry night! And no ware wolves! he he. That would be weird.

Answer 5

Well some things i can think of are

1) The tides would stop - it is the pull of the moons gravitational field that causes them. This would affect all life in the seas, the movement of plant and animal life - food sources etc.

2) There is anecdotal evidnece that menstruation is connected to the moon - i am not sure whether this is trus - if it is fertility might go a bit squiff.

3) Werewolves would get cured.

Answer 6

I think the moon is slowing down our rotational speed so wuthout the moon our earth would have more consistant day/night thing but the wobble in the earth would be unpredictable since the moon seems to stabilize this wobble. Life might not be here today if were not for the moon stabilizing things but not sure about that maybe it would just look different then we know today.

Answer 7

Besides the obvious... which everyone else has stated (tides)...the moon provides one very useful function for us here on earth, often overlooked.
It provides some protection from meteors/asteroids which would otherwise hit the earth & cause havoc. Naturally, some get through & do hit the earth.

Answer 8

Spring tides come twice each month and equinox twice a year.
The difference would be the tidal difference between spring tide and neaps 'plus' the difference between equinox and whatever reading is taken in the middle of equinox.
Would it effect the weather?
Yes but only where Gulf Streams and the like exist.

All of the above is my opinion and not a scientific fact.

Answer 9

Well when we are speculating...
Ok if there is no gravity pull of the earth..honey 1st thing to go will be our atmosphere.. and with no gases (O2) to breathe.. no one will survive to see is moon disapears or not...

generally.. moon causes the high tide and low tides.. but with no gravity..All the water will evaporate and earth will look like mars

Answer 10

Not much.
Tides would diminish but there would still be small tides caused by the sun.
Some animals would probably have trouble if they use moonlight for hunting or such like.
Astronomers would go mad trying to work out what had happened.
