What would happen if the earth stopped spinning?   
Hi:

The 1st and obvious answer is that half the world would be night and the 
other half would be day without change.

However, what would be the less apparent effects? For example, how would 
it affect the ecosystem, the climate, polar ice caps.

Lets assume that the Earth stops spinning in a manner such that it is 
the time [in terms of sun/earth orientation] always 4:30 AM 
standard-time in Stamford, Connecticut. Let's also assume that the 
Earth's movement stops when it is summer for the southern hemisphere and 
winter for the northern hemisphere.

What would be the effects? That it would be always be summer in 
Australia and winter in Canada is self-explanatory.


Thanks,

In order to stop the seasons, you need to stop the Earth from orbiting 
the Sun as well as stopping it spinning. But if you do that, there's 
nothing to stop the Earth from falling into the Sun.

The seasons would occur as usual even without axial rotation -axial
rotation generates  daylight and darkness and changing orbital
orientation to the central Sun generates seasonal daylight/darkness
variations,

Standing on the Earth's  polar axis is equivalent to a non rotating
Earth,it stands to reasons that seasonal daylight/darkness variations
are at the extremes while the effect becomes less variable towards the
Equator (where no seasonal variations are seen).

Through this reasoning,there is a much better way to explain the
seasons but alas,geodynamics is in a poor state at the moment and
replacing the pseudo-dynamic of variable axial inclination with a new
orbital component which causes the daylight/darkness variations may
take a while.

Hope this helps.

At the poles as well as the equator, the season is pretty much constant. 
  The former being extremely cold while the latter being extremely hot.

Also, wouldn't the one side of the world remain night while the other 
side day if the earth's completely stopped moving?

The Earth would have to rotate on its axis once a year in order for one side 
to always be facing the Sun.

The night side would get very, very cold, maybe not cold enough to freeze 
nitrogen, but perhaps cold enough to freeze CO2.  A huge ice cap would cover 
North America much like the Antarctic cap.  The day side would get very hot. 
Equilibrium temperatures in places like China and Australia could be as high 
as 60-70 C.  It would probably only be possible for life to flourish in the 
"twilight zone".

The atmosphere would be able to redistribute heat around the globe to some 
extent; there would be drastic changes in the sort of weather we have now, 
where the patterns and flow are largely driven by Earth's rotation (Hadley 
Cells, coriolis effects) and powered by heating effects of the sun.

In this description the earth still rotates once per year
if the earth did stop spinning, the length of the day would be
the same as the length of the year. However, I don't beleive
that would be a stable condition.

The transfer of angular momentum to all the loose objects (people, 
trees, soil, oceans etc) would fling it all off at high velocity, 
removing the entire ecosystem in one fell swoop. The air, if any was 
left after all that stuff had hurtled through it, would continue to 
rotate at around 1000 mph (near the equator) for some hours, scouring 
off anything remaining on the surface.

As for night/day, winter/summer, this isn't dependent solely on the 
earth's rotation - the earth's orbit around the sun is a factor in both, 
and the main factor in the seasons.

If you're unsure about the day/night point, hold a football at arms 
length with the logo pointing towards a distant tree. Now, with the 
front logo pointing to that tree, move the football to your left. Notice 
that you're now looking at a difference side of the ball. You're the 
sun, so the side nearest to you gets the sun.

Not based on the stupid scenario that YOU have set!  Based on the planet 
having "...completely stopped moving", it would have a "day-length" 
equivalent to the length of it's year, with a "night" roughly 6 months long 
and a day 6 months long.

The Moon is "tide-locked" Moron, meaning that its rotational period (it has 
one!) and it's revolutional period are identical, causing one side to always 
face the center of it's orbit (toward Earth).

Technically no. If the planet completely stopped moving, then assuming
the Moon didn't immediately hit it, we could say goodbye to the Sun,
Moon and other solar system planets in pretty short order. It'd be night
everywhere in pretty short order and too cold for life a bit after that.

The issue is that the solar system is orbiting the galactic centre. If
the Earth stopped, the solar system would continue on without us.

Lather, rinse, repeat for movement of the galaxy, though it'd take a
while before we were outside the Milky Way, and I doubt anyone would be
a live to see it.

There is no "stopped".  Though if it were stopped in any inertial
frame, it would not be orbiting the galaxy.

And even then the orbital eccentricity though small would allow some 
minor seasonal variation at the edge of the terminator.

Depending on whether or not the Earth is not rotating wrt the fixed 
stars you will either see the same stars in the same places every night, 
or an annual change as the Earth moves along its orbit with one side 
always facing the sun if it is not rotating relative to the mean solar 
position (Mercury is tidally locked to the sun in a 3:2 resonace).

The moon would still orbit the Earth once a month or so and tidal drag 
would slowly spin up the Earth and very gradually slow the apparent 
motion of the moon. If the same side of the Earth is always facing the 
sun then tides would be entirely due to the moon with much less 
amplitude and less monthly variation.

Antarctic winters in 6 months get down to well below -70C so after a 
year or so there is a good chance the cold side will be -80C and solid 
CO2 will freeze.

Weather would be pretty odd without any rotation. I expect the 
terminator would bear the brunt of storms transferring energy and water 
from the hot to the cold side of the planet. After a while I suspect all 
the precipitable water and most of the CO2 would be stuck on the cold side.

If the Earth stopped rotating then you'd still have a cycle of light and 
dark; you'd have a year-long day.

No, its gravitationally locked to the sun but has still rotates, and its 
rotational and orbital periods are not equal (ratio of 3:2 I believe).

A person standing on the North and South pole is physically not
axially rotating therefore your interesting question is not
hypothetical but an actual condition.With this discovery,you can work
through the reasoning where a person at the polar axis experiences
variations in daylight/darkness throughout the year while not axially
rotating.

It is possible to work with variations in daylight/darkness as they
represent the closest gauge to what the Earth is axially and orbitally
doing without having to deal with local climate conditions such as
heat and cold variations.From this standpoint ,the extreme seasonal
variations in daylight/darkness at the polar axis has to come from
somewhere and that is when you look at what orbitally occurs as the
Earth orbits the Sun.

No,that is what is so fascinating,a location will orbitally turn
through 360 degrees with respect to the central Sun thereby creating
variations in daylight/darkness .Again,day and night is due to axial
rotation but variations in daylight and darkness is due to an orbital
component.Use the unique and extreme rotation of Uranus to see what
happens as a location orbits the central Sun over the course of a
year.as the rotational orientation keeps point to the same point in
the sky but orbitally changes through 360 degrees  with respect to the
central Sun like a crank pin keeps point to the same external point
but changes to the central shaft -

Just take your time,rember that there is a point on the Earth surface
that does not rotate yet experiences extreme seasonal variations in
daylight/darkness and remind everyone else here of the same fact.

This is quite new and you will not find a similar explanation,which
means that you will have to discover most of it yourself.Good question
btw.

Good !

If the Earth stopped rotating you would lose your  'axial tilt'
explanation  for seasonal variations in daylight/darkness which occur
anyway  regardless of  axial rotation and orientation.The seasonal
change arises from orbital motion along with the global variations in
the natural noon cycle when allied with axial rotation and using
natural noon as a benchmark.

Very rare that a large modification such as replacing variable axial
inclination with a new orbital component is allowed to drift as this
insight has,but it is done nonetheless and there for any person who
wishes to reason through the details.No person who truly grasps it
would dare pretend that the insight is not  a huge departure from
previous' variable axial tilt'  explanations or try to assimilate the
insight without regard for the  enormous and sometimes painful effort
put in.

It used to be believed that it was tidally locked in an 88-day orbit
so that one side always faced the sun, but this was discovered to be
false in the 1960s.  Larry Niven among others write a science fiction
story with this premise.

You still haven't defined what you mean by "stopped rotating".

Sloppy question.
Which inertial frame 'Earth stopped moving'?

1.  Solar:  Earth swings around sun, facing it.
             Light  & dark sides.

2.  Galactic:  Earth swings around sun, facing center of galaxy. 

                Year-long day.

3.  Extra-galactic: Earth stops while sun goes around galaxy.
                     Very dark.

4. Other ?

Permanently very cold in shadow area and very hot on other side.
Everyone and virtually everything would live along a thin circular
zone where the sun would be permanently on the horizon. Only a small
portion of the earth would be inhabitable. There would be only two
directions to travel, east or west.

... underlying your question is the one concerning the cause of both
Earth rotation & revolution
... and in fact none has answer to that question except the one
peddled forth by the Academic Cretins i.e. inertia resulting from some
alleged "Gros Boum" idiocy some Zillions yearz ago !
Okay ?

I am tellling your here now,  that if the Earth stopped rotating the
whole system would do likewise,  and it would mean that Sun which is
the driving force in accordance to the True Geology,  would have
stopped rotating as well
( non-obstant the certitudes processed from of the conditionned mind
of poor John Kepler, a faithful of Glaciations, Continental Rafting
etc   )

You mean if the Earth's rotation were to slow to the point that one 
hemisphere always faced the sun. 

> Let's also assume that the

This part is meaningless because summer and winter are defined by the 
relation of earth's rotation axis to its orbital axis. Unless you're 
asking that the axis of the earth's rotation changes so that it's at the 
arctic circle at approximately the -2h GMT time zine. (I may be off on 
the longitude; that was just a mental calculation without pencil and an 
envelope). 

> What would be the effects? That it would be always be summer in

Well, depending on how quickly this change occurred, it could wreck the 
ecosystem.

Oh, it's you! I was expecting you to show up at this party. 

Now you're calling axial inclination a pseudo-variable? That's good.

Hah! That's the most idiotic thing you've ever said! 

Do you think that if someone were to set up a time-lapse camera at  the 
south pole, above that chrome hemisphere, say on the summer solstice, 
that the sun would stand still in one place? 

I recall seeing a movie where someone did exactly that. The sun quite

Brain? Brain? What is brain?! 

You need to work this out yourself with a ball and a lamp. Put the lamp 
on a table in the middle of the room; remove the lampshade. Hold the 
ball in your hand and walk in a circle around the lamp. Watch what the 
shadow does. 

(Under no circumstances do this counterclockwise! Your neighbors will 
think you're doing witchcraft.)

In the third episode of Star Trek: The Next Generation, young Wesley 
Crusher fell over a barrier into some flowers. Those flowers were in an 
Enforcement Zone that day, so Wesley was sentenced to a quick and 
painless death. There's a lot to be said for that sort of thing.

So in other words, you're poisoning the conversation by saying ahead of 
time that anyone who disagrees with you is stupid. That's okay. You're 
free to present convincing diagrams and measurements that back up your 
preposterous claims.

The same face of the earth to point towards the sun at all times.
ie the earth's rotational and orbital periods to be identical.

I suspect that to achieve /that/ the earth would have to a ) be moonless 
and b) a lot closer to the sun. The gravity of other bodies in the solar 
system has a nonzero effect on the earth and would break any tidal lock.

Without thinking, it 'feels' to me that the Moon would drop into

has gravity weakening effects. One of those Hollywood moments where
things stall, and

According to theories it is the contrary. Spinning adds to gravity,
more noticable in spiral
galaxies where this dark matter is 9 times the visible mass.

What??? That makes only a little bit of sense. To do calculations of the 
moon's orbit, all you need is the earth's mass, the moon's mass, the 
distance between them, and some specifics about eccentricity, orbital 
inclination, etc. You don't care about the Earth's rotation. 

Yes, the Earth's gravity as measured at the surface is a little lower at 
the equator than at the poles, but you can't measure that difference in 
orbit. 

But you've contradicted yourself. You say that "that the rotation of 
Earth has gravity weakening effects" yet if the earth's rotation should 
stop, the moon would fall into the earth.

According to what theory? 

I strongly suggest you pick up a couple of textbooks on astronomy and 
learn their content before you write such opinions. They make you look 
like someone trying to be mistaken for ignorant.

A location does not keep the same face to the Sun but changes through
an entire 360 degrees with respect to the central Sun.There are actual
images of the Equatorial rings of Uranus showing this  feature of
orbital motion -

http://asymptotia.com/wp-images/2007/08/uranus_rings.jpg

The  Earth does not have those useful Equatorial rings which
explicitly show that a location changes its orientation through 360
degrees and take an entire orbit to achieve this but it should be
inferred without question  by any intelligent person -

You operate off celestial sphere geometry and a false view where the
Earth keeps the same side to the Sun.In the absence of axial rotation
you would not get a year long day as some have correctly pointed out -

http://www.pfm.howard.edu/astronomy/Chaisson/AT401/IMAGES/AACHCIT0.JPG

I have to remind myself that  men still cannot explain the second
greatest effect after day and night - the variations between daylight
and darkness everywhere except at the Equator.The lack of a central
authority to actually deal with the matter and come to a satisfactory
conclusion is lacking.

A original poster asked a very straightforward question regarding
axial rotation and what occurs if it stopped in terms of daylight and
darkness,it does not require anything other than the Earth's behavior
to the central Sun and should not involve any other factor outside
orbital motion.


Btw,a person axially rotating at the Equator is moving at roughly
1.000 miles per hour and diminishes to 0 miles an hour at the polar
axis hence a person standing on the polar axis is not axially rotating
nor the ground beneath him.That is a fact for everyone.

Quick question - is crude oil denser or less dense than water? Then how

It depends on how you define "stopped spinning".
Technically in most gravitational systems the length of a spin slows
down to a length of a revolution with one day = one year.
Focucault's pendulum would still precess with a one year
cycle indicating there is still spinning going on.

Do you know when the wheels on your car stop turning/spinning/
moving.The guy had a good question if you can actually understand the
concept of a spinning Earth.

Do you know when sometimes you are outside you can see the stars and
at other times you can see a bright and shiny ball in the sky ,well
that is caused by a spinning Earth and if it stops spinning you get a
year long day of daylight and darkness.

Foucault's pendulum is based on axial rotation occuring beneath the
swiinging pendulum and at the poles,where the  rotational forces
acting perpendicular to the rate of change is absent,the ground
registers a movement beneath the swinging pendulum of 24 hours 360
degrees,not a second more or a second less -

http://www.phys-astro.sonoma.edu/people/students/baker/SouthPoleFoucault.html

Considering that I have yet to meet an individual who is capable of
recognising rotational geodynamics involved in crustal geodynamics or
people who have an adult  regard for physical considerations in
respect to astronomical,geological or climatological causes and
effects,people will have more regard for your erroneous response and
conclusion than they will for working through the physical effects to
come to a satisfactory conclusion.

Btw,you are not to blame,you are just doing what everyone else is.

No wonder astronomy is in a poor state - there is not the slightest
sign that somebody actually enjoys working with the motions of the
Earth.Give credit where it is due,the follwing article more or
less,with a few minor errors,gets it right -

T"he plane of the swing of the pendulum bob is now independent of the
surface of the earth which was imparting a force to the bob before it
was released (through the holding point). As noted previously, the bob
is still spinning with the Earth (a spot of the bob will spin with the
Earth), even though the bob is no longer turning with the Earth. Thus
the Earth continues to turn underneath the swing of the pendulum while
the swing of the pendulum remains in a fixed plane that doesn't rotate
(turn)."

http://en.wikipedia.org/wiki/Diagrams_For_Foucault_Pendulum

At the North pole,where axial rotation is essentially  absent,a person
technically  experiences a day long year in terms of daylight and
darkness thereby determining that quite apart from axial rotation,a
location chnages its orientation a full 360 degrees with respect to
the central Sun.

If axial rotation ceased,the pendulum would act as though it were
located at the Equator at every latitudinal point between Equator and
pole.If axial rotation ceased,the Equator would also experience a year
long day in terms of daylight and darkness.

This stuff is just fun for me and I do not see why it does not provide
for a lively discussion.Perhaps the art of discussion has been lost
and all that exists are the complainers .

That is not true. At either pole one can see the 24-hour rotation of the 
Earth by observing the sun, the moon, and the stars moving around the 
sky.

Go ahead and discuss what a person will experience at the polar axis
in terms of daylight and darkness throughout an annual orbital cycle
(a year in other words).

If axial rotation ceased,a location at the Equator would behave in the
same way as the polar axis location insofar as it would turn through
360 degrees with respect to the central Sun and take an entire year to
do it giving the experience of a year long day of daylight and
darkness.It all depends on how much focus you place on seassonal
differences produced by the Earth's motion to the central Sun, rather
than wandering off to equidistant celestial sphere geometry,if a
person keeps things restricted to the fairly short distance between
the Sun and the Earth and intepret the motions correctly they will
reach a satisfactory and enjoyable conclusion.

Go ahead and try  and get a discussion going,the  collected
information  of the Pendulum,the time lapse footage of Uranus or
whatever other information can be brought to bear on the fact that a
change in the orbital orientation of a location replaces the pseudo-
dynamic of variable axial/equatorial inclination as the cause of the
seasons.In short,you are supposed to enjoy working with a new orbital
component and with that,I leave this for a while.
