What happens if earths starts rotating in opposite direction??

Question

What happens if earths starts rotating in opposite direction?? (i mean to say is only rotation and not revolution around the sun).. will gravitational force be affected by this??

Answer 1

it has happened in the past.. n it will happen again.. the earth tips over every few million years.. the earth tips over. so the north pole will be in the south.. nd everything will be the opposite of the way it is now.

the north pole will be warm.. the equator could freeze.. n all this.. but we may not witness this in out (human) lifetime..

p.s. when this happens the earth rotates in the opp. direction as to what it was doing before the flip..

Answer 2

If you mean the Earth just suddenly stops moving in one direction and instantly changes spinning direction, then, considering just how fast the Earth is spinning, everything will be jolted in the other direction so forcefully there'd be a cataclysmic event that would destroy everything on the surface of the Earth as well as probably parts of the Earth's crust.

If you're just talking about a magical change, or a gradual change or even a parallel universe where the Earth rotates in the opposite direction, then here might be some differences:
1) The sun would set in the east and rise in the west.
2) Hurricanes and tornados would rotate in the opposite direction.
3) A change in the water and air currents around the globe.
4) A disruption of the Earth's magnetic field, possibly causing the north and south poles to magnetically switch. (compasses would point south)
5) A possible change in values of the hour, minute and day (depending on the speed at which the Earth will rotate)

Since gravitational force depends solely on the mass of the objects involved, then no; the gravitational force will not change.

Note: What preety could possibly be talking about is called precession. This is when the Sun's gravitational pull on the Earth causes the Earth's pole to actually rotate. This will not cause the Earth to flip over, the Earth will retain its 23 degree incline, nor will it cause the Earth to spin the other way, but it will cause the seasons to change. So in about 12,900 years, what we call summer now will actually be winter, and vice versa.

Hope this helps.

Answer 3

Klo-Jann:
I think gravitational force will not be affected by this.
However:
1. each day starts backwards
2. east and west definitions have to be corrected (as the earth spins towards the west then)
3. sunset comes before sunrise and children will get confused (because the textbooks say the sun rises from the east but not the west)

Answer 4

on my idea, nope, it will not affect the gravitational pull in any way, assuming that the speed of the rotation of the earth is still the same. But you better get your new calendar and watch/clock readjustment

Answer 5

The world would blow up because it would have to stop to start spinning the other way, and there would be no gravity to hold everything in. I guess none of us will be there to see what happens next. If it did just start spinning the other way though (magically) nothing would happen. The sun would rise in the west and set in the east.

Answer 6

Nothing much will happen except

The sun will rise in the west and set in the east

The speed may change slightly so our perception of the hour will change

During the transition from one dir to the other we may have some bizzare weather conditions

Answer 7

gravitational force? i don't think so. but i'm sure you wouldn't want to be on the earth when it swiched directions.

Answer 8

Nothing different except the days and nights and the time.

Answer 9

it will collapse with the sun as the sun will suck the earth

Answer 10

Our moon will be highly confused.
