It would be extremely difficult. You would have to somehow put an unbalanced force opposite the initial direction of rotation. I can think of two ways to do that: 1: direct an external body into a location on the surface so that the combined system would have zero angular momentum 2: Use a mass driver to throw mass away from the earth at high speed. For option 1, you might be able to run an asteroid . The second moment of the earth is something like 10^38 kg

∙ 14y agoIf you are hanging motionless in space up over the south pole, looking down at the earth, then yes, you see the Antarctic ice rotating around the south pole in the clockwise direction, which is from west to east.

∙ 13y agoIf you're hanging over the north pole watching it, then you'd say it does. But if you're
watching from over the south pole, then you'd swear the earth rotates clockwise.
You'd be correct in both cases. The direction depends entirely on where you're watching from.
There's no "real" direction.

∙ 13y agoThe evidence says, emphatically, YES!
During its early formation, the Earth would have been spinning considerably faster than it is now.
The formation of the oceans introduced tidal friction - the action of the oceans against the surface of the crust. This began a slow-down process that continues to this day.
A major factor influencing this slow-down is actually our very own moon. As it orbits, rather like a ball on a string, rotational energy is transferred from the Earth's spin to the moon's orbit, resulting in the gradual slowing of the Earth's rotation. The same action causes the moon to recede further from the planet as it gains orbital velocity.
In real figures, the Earth is gaining about a 0.002 seconds every century while the moon gets about 38mm further away each year as its orbit gets longer.
It is estimated that it would take about fifty billion years for the Earth and its moon to reach an equilibrium, with the Earth taking 47 days to complete a rotation.
Resetting our clocks will not be a problem as our ageing sun will fry Earth to a barren crisp about 2-3billion years from now.

∙ 14y agoThe earth will stop ratating 2147. Scientist have researched this over about 30 years and came up with different answers, but say that this is the most accurate! They came up with other answers like 2619, 2567, 3104, but asi said this is the most accurate.

∙ 14y agoIf what you meant to ask is "How would the length of the solar day change if the Earth ROTATION ON IT'S AXIS were suddenly to reverse direction? Strangely, the length of of the day would not change at all assuming that the rotation speed remained the same. Unfortunately though, there would not be any of us around that would survive such a shift. Too bad, it would really be nice to see the sun rise in the west and set in the east for a change. It would be like being on Venus.

For option 1, you might be able to run an asteroid . The second moment of the earth is something like 10^38 kg·m2, and its angular velocity is 2*pi/86400 radians/sec. An "asteroid" with a mass of, say 10% of the earth would have to impart an opposite angular momentum, so it could have a velocity rmv = I*omega v= 10^38 kg·m2 * 2*pi/86400 rad/sec / (6.4 e6 m * 0.1 * 6x10^24 kg) which is a mere 1.9 km/s, if my calculations are correct. So you could probably get better results with an asteroid that is 1% of the mass of the earth, but had velocity of 19 km/s, about how fast the earth moves around the sun. Ceres has a mass much less than this(1x10^21 kg vs 5x10^24 kg), so it would have to be tossed in appropriately faster. This is all vector stuff, so you would have to get it in just the right direction, too. For example, it could fly fly in from due east and crash into Venezuela, thereby stopping the rotation of the earth and ending the regime of of Hugo Chavez. The benefits of either of these effects are left as an exercise to the student. It would seem that this probably happened to Venus at some time in the past, since it has basically no rotational angular momentum now. Very strange. The other alternative could be enacted by building a string of nuclear generating stations along the equator, then using them to toss mass eastward into space. Suppose you tossed mass out in 1 kg pills at somewhat above escape velocity, say 10 km/s for the sake of argument. Since the station is 6400 km from the axis of the earth, then each would take away rmv=6400 km * 1 kg * 10 km/s = 64x10^9 kg m2 of angular momentum. You would need to toss off N = I*omega/h = 1.14e23 of these things to stop the earth. The energy required to accelerate them would be 1/2 mv2 = 50 MJ. Since a decent nuke plant can generate about 1 GJ/s, one reactor could generate enough to fire off 20 projectiles a second. Tossing off 1.14e23 of them would take about 180 quadrillion years, or about 10000 times as long as the universe has been around. The value of this exercise has also not been demonstrated.

∙ 12y agoFrom a physical standpoint, this is next to impossible, so no. The Earth has an enormous amount of rotational inertia that would have to be cancelled out (and then some) in order for this to happen.
It's not actually impossible... there are (unlikely) scenarios in which it could occur... but unless the change happened over an extremely long time period, the consequences of it would be devastating.

∙ 16y agoTime would not go backwards, but we certainly would. And if it happened in a few moments, everything and everyone on the planet would be destroyed. You would have to be very near the poles in order to survive. The earth doesn't come with a Star Trek Inertial Damper system.

∙ 15y agoThe apparent direction of rotation of the earth depends on whether you are looking at it from above the north pole or above the south pole.
From the north pole it appears anticlockwise and from the south pole it appears clockwise.

Why is there seasons on earth?
Because:- 1) The Earth orbits the Sun and take one year to make a revolution. 2) The Earth spins on its own axis (like a child's top) but the axis of spin (a line joining the north and south poles) is inclined (not at 90 degrees) to the plane in which it orbits the Sun. This mean that at one part of the orbit the north pole is pointed towards the Sun and half a year later the south pole is pointed towards the Sun. This gives the seasons.
The revolution of the earth causes the seasons right?
No, the revolution of the Earth (its spin about an axis through the north and south poles) causes night and day. The Seasons are cause by the fact that the Earth's spin axis is tilted and by the orbit of the Earth round the Sun.
Do tornadoes spin clock wise or counter clock wise?
It depends on the hemisphere of the Earth that the tornadoes are in. In the Northern Hemisphere, like all low pressure systems they spin anticlockwise. However, in the Southern Hemisphere they spin clockwise. This change of spin is due to the Coriolis effect. Similar to water down a drain. Tornadoes are a very localised low pressure system in extemis. Of slightly higher eye pressure are hurricanes, typhoons, cyclones, and willy willy's. Hurricanes ; Carribean/USA Typhoons ; South China Sea. Cyclones ; Bay of Bengal. Willy Willy's ; Australia ( An aboriginal name). These atmospheris phenomina occur elsewhere in world, notable Brazil, and South East Africa., but they do not carry a name. Of slightly higher central eye pressure again are normal atmosphereic depressions. The anitcyclones are regions of the highest pressure of all.

How does the earth spin around?
Earth spins around its axis(or imaginary line from the north pole to the south pole) by gravity from earth itself and the surrounding planets.
Which direction would the earth appear to spin if you could observe it from the below the south pole?
clockwise
Which direction would the earth appear to spin if you could observe it from below the south pole?
clockwise
How is the earth is rotating whether in clockwise or anticlockwise?
It depends on where are you standing, over the North pole, or over (or should I say under) the South pole. If you are at the north pole, the Earth appears to spin counter clockwise and at the south pole, clockwise. If you view the Earth from space, with the north pole up and the south pole down, it will spin moving left to right at the equator.
What happens when A high altitude wind system is traveling south from the Equator toward the South Pole?
be deflected to the east by the Earth's spin.
What country does the Earth spin around?
The Earth does not spin around a country. It spins on its axis and revolves around the Sun. Neither end of the axis is located in a country. The north pole is located in the Arctic Ocean and the south pole is located in Antarctica, which is a continent, not a country.
Is there a north pole and a south pole on mars?
Yes. All of the planets, which spin on their own axes, have a north and a south pole.To my knowledge, Earth is the only planet upon which axes may be found. I do believe that all planets that rotate around their axis have a north and south pole.
What prevents wind from blowing in a straight line from the North Pole to the equator?

What is the complete spin of the earth that takes 24 hours?
The earth spin around its axis in almost 24 hours.Consider for sake of argument that an invisible line is drawn through the earth vertical from the south pole to the north pole (like a top). The earth spin around this line approximately once every 24 hours.This axis is, however, really not vertical from the north to the south pole. Instead this axis is tilted 23.5 degrees.See this short video on YouTube: http://www.youtube.com/watch?v=Zm_-ewT6-yIor read this article: http://www.physicalgeography.net/fundamentals/6h.html
Why does mercury have a North Pole?
All planets, moons, suns, stars, and so forth spin like a top. There is a top and bottom where the spin is almost nothing. These are called the poles. 'North' pole and 'south' pole are terms used because the earth is full of iron, and therefore like a huge magnet with . . . a north and south pole. Other planets, suns, stars, moons, and so forth may or may not have iron cores, but the north and south pole convention applies anyway.
How in miles per hour does the earth spin at the north pole?
about 900miles to 1100miles
Does the earth spin on its axis?
Yes. The Earth, if viewed from the North Pole rotates in a counter clockwise rotation.
