What if all ppl on northern hemisphere did ....?

Nothin would happen.\nIf you consider two bodies the earth (name it E) and a large mass (m). \ninitially M rests on E. and you lift mass M. the force used to lift it will also act on E.\nAlso if you consider the mass M and E. as a system force exerted on dropping M would be internal and since internal forces do not cause acc. the Earth will not get unbalanced.\n\nThats good for us isn't it...

The northern hemisphere will suffer a prolonged agony and barbarity in a nuclear exchange of the two superpowers. At a minimum, 1 billion souls will be lost, mostly in the US, Europe, Russia, China and Japan, another 1 billion will die from radiation sickness from the fallout.  That's half the population of the planet. \n\nAnd those in the southern hemisphere will face extreme hardships from the impending nuclear winter that will eventually reach them.  Without sunlight, all plants and eventually animal life will die out.  Carl Sagan concluded that there's a very low threshold for Nuclear Winter, far below the 5,000 megatons that would be detonated.\n\nIts no wonder that Einstein said that WW IV will be fought with stick and stones.

Two Hemisphere...may be

Yes, but to a degree. The horizon line is going to be different, so you will see some of the stars, although a bit displaced, that the Northern hemisphere sees, and you will see a lot more that is only visible to the Southern hemisphere.

Countries on the southern hemisphere. Think about the tilting earth as it orbits. Australia would be a good example.

the tidings of the sea would stop existing, and basically everything containing water (including the human body) would OR die, OR very urgently have to adapt! Mmmm, no, we'd die. Even female menstruation depends on the moon...

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:

we would notice a change right away, the direction and position of where the sun's rays hit are what cause our temperature differences. if we had a drastic 90 degree turn in our axis it would throw off our global climate over the course of a few decades. changes would happen drastically however, and until things settled down over those decades or even centuries we would be in a state of climate-chaos

I do agree,they claim el nino is responsible,some claim global warming. The semi cold weather with wet,cloudy days is depressing not to mention it brings on aches and pains......Illness The cold snowy days seem to bring excitement, to cold for the germs. My personal theory is the whole Earth has shifted orbit just enough to mess the weather up. Scientifically I would go with global warming or the green house effect. We have used and released so much freon or R-12 into the atmosphere, plus other pollutants its really damaged are enviorment all for comfort. Maybe we should go back to horse and buggies..lol

I read in new scientist that there there is a certain current in the Atlantic that transports hotter ocean water from the south to the north.\n\nWhat happens here is the arctic ice will cool the temperature of the water down and it will thus flow south again.\n\nWith global warming there will be a constant flow of hot water to the north thus raising the water level there. So all places on the northern hemisphere would get affected first. \n\nI'm not too sure I got all the facts right but it has something to do with a current though.

Earth is rotating at a speed of about 1100 miles per hour. If our planet suddenly stopped rotating, the atmosphere would still be in motion at that speed. The atmosphere would be moving so fast it would literally sweep the land masses clear of anything not anchored to bedrock, this would mean rocks, soil, trees, buildings, people and animals. All would be swept up into the atmosphere.\n\nIf the Earth's rotation slowed down gradually over millions of years, and this is the most likely scenario, it would be a very different story. If the Earth slowed down to one rotation every year, called synchronous rotation, every area on Earth would be in either sunlight or darkness for one year. This would be similar to what the Moon goes through where for two weeks the front side of the Moon is illuminated by the Sun followed by the front side being in darkness for two weeks.\n\nBut what if the Earth stopped rotating completely? In that case, one half the Earth would be in daylight for half the year while the other side would be in darkness. The second half of the year it would be reversed. Temperature variations would be far more extreme then they are now. The temperature gradient would affect the wind circulation also. Air would move from the equator to the poles rather then in wind systems parallel to the equator as they are now.

nice question  theoretically you would be pulled in every outward direction, which would be interesting.

if you mean..." If the worlds oxygen ends what would happen?" then that is obvious. the worlds would slowly deteriorate\n\nLife would end

I'm sure the Earth would think so...\n\nhttp://threeleggedlegs.com/humans/

Both the northern and southern hemispheres have winter and summer solstaces, except there are in reverse order: i.e. when the north is having its winter solstace, the south is having its summer solstace and vice versa.\n\nSo which one do you mean? During the north's winter solstace, it is summer in South Africa; and vice versa.\n\nBe aware though, that the earth experiences its apogee from the sun near the time of the northern hemisphere's summer solstace and its perigee near the sun during the northern hemisphere's winter solstace.\n\nThis may easily contribute to the northern hemisphere's milder winters and summers than the southern hemisphere, and explains why the Antarctic is colder than the Arctic.

I've been there. Its sorta like NORTH-SOUTH Hemisphere. Its either 1 degree celicus or 92 degrees Farenheit. Trust me...BE PREPARED!

What century are you living in?  Consider the people that have made non-stop around the world flights, not NASA, but other pilots, such as the pilots of Voyager.  Would they just have come to the edge of the world and had to just flip over to the other side to get back to where they took off from?
