how do earth spins ?

Answer 1

Rotation (not orbit) goes in the same direction (west to east) for all planets in our solar system. The Earth spins at about 2000 Kph. Since there is some temperature in space, the spin WILL slow ever so slowly. By the way, gravitational pull of the sun causes the Earth to ORBIT, while the sun's spin prevents the orbit from decaying. The MOON HAS NO SPIN, the Earth's SPIN (not its gravity alone) prevents it from coliding with us. Spins started with the solar system, they are NOT a function of gravity.

Answer 2

As far as what makes it spin...it's the after-effect from back when the earth was forming from the dust cloud that the entire solar system was formed from. Much like when a weather pattern causes the air to spin in circular motion here on earth, a similar phenomenon happenned during solar system formation that resulted in the formation of the sun and all the other planets and moons. Add gravity to the event, and you'll have all this dust cloud mass collapse upon itself...the earth literally spun and fell together. Even though that dust cloud is now gone and has merged into being part of the earth, the energy of the initial spin continues.

Answer 3

The Earth spins around itself about it's own axis and around the sun. The earth spins from west to east with a speed of 1610 miles per hour.The Earth spins around the Sun in an elliptical orbit.

Answer 4

Earth Spins, i.e rotates, around it's North - South Axis (in apparent West to East), in a plane almost perpendicular to the plane of it's revolution around the Sun. Obviously each rotation is of 24 Hours.

Answer 5

Some say that the earth's rotation was accelerated by the meteor that caused the formation of our Moon. In the process of blasting a Moon sized chunk out of the planet, it's possible that the meteor could have hit the planet in such a way to cause the planet to spin. Ex. Try standing up a quarter on a table holding it in place with one finger on one hand, and with the opposite hand flick the quarter on it's edge and it will spin to form a sphere. The finger that you flick the quarter with is the meteor in this example.

Answer 6

Good question many answers.

First of all it has a center of gravity and gravity therefore a point on which to spin, the gravity of the moon for one keeps it spinning, convection, momentum resulting dominant wind and ocean currents friction from space debris in its revolution affects its rotation even a close by comet could warblize it eccentric.

The most important reason is that it is more natural for things to spin than not spin. any light or convection will spin by change this is why planets are orbs as most is round and spins.

Answer 7

Earth spins due to centrifogal force acting of gravity exerted by sun. this is only reason why all planets spin.

Answer 8

The earth spin clockwise on its axis due to the heavy gravity of sun but we dun get pulled into the sun because the effect of gravity is not tht stong tht it will jus suck us rite into it like a vipersuction or something like tht so yea tht y we dun get pulled

Answer 9

West to East _ on it's axis, (which is tilted by about 23.5deg)_ hence sun seems to rise in the East and set in the West.

The exact causes and mechanism that causes this rotation is a subject of research and not known for sure.

Answer 10

there is nothing to stop to earth from spinig in the space,and because of that there is nothing to resist that's why earth spins.
