What would of happened if the earth did not spin?

Spin relative to what?\n\nThe spin of the Earth about its own axis causes day and night but only because the spin is not synchronised with the orbit of the axis around the sun.  Mercury spins once on its axis for every orbit and so always has the same face to the sun.  It could be said in this case that Mercury does not spin, but that is only relative to the orbit of Mercury.\n\nImagine a frame of reference that is fixed in space like the grid lines on a map.  If a planet did not spin on its axis relative to this reference, then it would have a day/night cycle that took one orbit to complete (this would be one year for the Earth).\n\nIt is also believed that the spin of the Earth contributes to the generation of the magnetic field, so if the spinning stopped or slowed (relative to any reference) we could loose the magnetic field and thus be exposed to higher radiation levels from the sun.

Actually, No.\n\nIf our planet was anything but symetric about the access of rotation, it would develop a tremendous vibration or wobble.  This would lead either to localized forces that would eject people and things beyond the gravitational field, or would result in the complete breakup of the planet itself.\n\nSorry.

Time is unconnected to the Earth.  The only immediately noticeable differences between normal Earth and a backward rotating Earth (NOT counting the moment during which the Earth stops spinning) is that water will circulate in the opposite direction in the ocean, counterclockwise instead of clockwise, and storms will rotate across the Earth in a different directional tendency.

theoretically, you would oscillate back and forth until friction slowed you down enough to come to a rest at the center of the earth.  it could be six flags newest attraction!

It can! Actually Earth's rotation is slowing by about 2.2 seconds every 100,000 years. The massive earthquake that recently caused the disastrous tsunamis around the Indian Ocean slowed Earth's rotation by a few micro-seconds. Don't worry, though, long before Earth stops spinning, our Sun will have left its current stable condition and engulfed the planet--in about 4.5-billion years.

Well, assuming you mean that the Sun just went out, but the Earth keeps orbiting:  probably for a little while.\n\nThe temperature would fall pretty quickly, though the oceans would give us a little reprieve; temperatures would remain livable near the oceans longest, and would be coldest inland.  Meanwhile, every photosynthesizing plant would eventually die from lack of sunlight, and soon every land animal would freeze or starve to death.  Even with modern technology, I doubt the last humans could make it for a couple of months.  Eventually, the atmosphere would rain, then freeze onto the surface, while the oceans would eventually freeze solid, or nearly so.  It would not be pretty.\n\nI've included two relevant links below:

It keeps spinning because of its angular momentum. The same reason why a top keeps spinning, until friction slows it down. But since the Earth is floating in space, there is no friction and it keeps spinning indefinitely.\n\nIt has not been spinning "since the Big Bang" because the Earth has not existed for that long. The Big Bang was about 14 billion years ago. The Earth is 4.6 billion years old.\n\nAlso, the speed of rotation is not constant. The tidal effect of the moon and sun are very gradually slowing the Earth down, making the length of the day very very slightly longer all the time. But it will take billions of years for a significant change in day length.\n\nIf the Earth suddenly stopped spinning, everything on the surface, especially at the lower latitudes, would be destroyed. The Equator is traveling at about 1,000 miles per hour (1600 km/h) and if the Earth suddenly stopped spinning the chaos would be incredible. But you don't have to worry about that because there is nothing that could possibly do that.

The seasons would be far milder. There probably still would be some seasonal variations because the earth is not always the same distance from the sun.\n\nAlso, it should be noted that even if the axis of rotation was oriented to be normal to the ecliptic, there is still a 435 day period Chandler Wobble to the earth's axis, caused by redistribution of mass on the earth's surface (and presumably within the earth as well) and the conservation of angular momentum.

If you're talking about some magical reversal without physical consequences, you already have several answers. But if you're talking about physical reality... the earth's mass is about 6.6 sextillion tons and its tangential velocity due to rotation is over 800mph at the equator. You can't just stop an object that massive, moving that fast without equally huge effects. The biggest effect would be friction. Energy is conserved and stopping the rotation of earth would convert the planet's entire momentum into heat. If the reverse happened quickly enough, the heat generated would probably boil the atmosphere and the oceans off into space. Everything on the surface would burn or melt. All life on the surface would end - everything would go up in smoke. \n\nIf the reverse happened slowly, we would lose the angular momentum of our orbit around the sun. Earth would leave its orbit and either fly off into interstellar space or plunge into the sun - either way would be pretty final.

No one is really sure yet. Astronomers and meteorologists are working everyday to figure out what is going to happen but the only theory is that....\n1- The earth stops rotations and can cause us to die\n2- The earth can get compressed into a small cubical.\n3- Nothing at all and we still live... which i hope is this.

As Debster92 pointed out, there is no way to stop the Earth from spinning once it starts.\n\nAlso, and perhaps more importantly, there is absolutely no way to get it started again if it did stop.\n\nThe angular momentum imparted on the solar system as it coalesced out the primordial gas cloud is what causes all the planets to spin and rotate as they do today.  If one were to somehow stop a body from rotating, it would take tremendous energy to get it started again.

Things would weigh less than on earth\n\nst

You would have to overcome the spinning motion of the atmosphere.  See my answer to your "if the world stopped spinning" question.  So yes, if you could reach about 900 mph going west, you would be counteracting the spinning of the Earth and eventually be somewhere else "without moving".  Now about the Earth's orbit around the sun...

Hmm. I think air would not flow as well. I would guess the atmosphere would stay hovering relative to each plane (6 of them), and perhaps intersect at the corners.\n\nEach side of the earth would have varying surface temperatures, unevenly distributed, which would make the air dramatically different temperatures. This would cause the air to move, possibly faster so it could be quite windy.\n\nHee hee what a weird question, I like it :-)

It's due to the formation of the planets themselves.  the gases and the dust spun around the sun as the star formed itself, and congealed into the planets we know.  And since they spun as they formed, they started the spinning on their axis as well.  \n\nBesides, we'd be either cooked or frozen if the Earth didn't revolve!\n\nHarley's wrong.  The moon DOES spin on an axis.  However, its spinning is on par with the Earth's spinning, thus you only see the one side of the moon.

If that direction were opposite the direction of the \nearth's rotation, I think the answer is theoretically yes.\nIn reality there's not enough mass of people relative to the mass of the earth to have any effect.
