what will happen if earth is turned upside down?

Australia will no longer be refered to as down under but Top Gun.

It will happen, but exactly when isn't known. Take a look at this website for current risks for those objects that do come relatively close to Earth ==>http://neo.jpl.nasa.gov/risk/

Depends on your point of view. If you're hovering above the North pole, the earth rotates counter-clockwise. If you're hovering above the South pole, it rotates clockwise.

obviously the effects will be huge, depending on the number of atomic bombs that is used at the worst case scenario the spin of the earth will change because the atomic bombs release so much energy. so earth could fall out of its orbit. 2 things could happen either  an Ice age or everything is going to be melted!\nin this case i don't think anyone would survive, not even president Bush

Well you seem  to have an inquisitive mind.\n\nsince the angular momentum of the earth is conserved, if all d cars drove towards east, this will prompt the earth to slow down its rotation speed eastwards, because there will be an extra component of the angular-momentum due to the cars.\nSo the rate of revolution of earth will decrease, which will lead to an increased daytime and night time.\n  But yeahh it will also lead to an immense traffic jam.\nDont even think about it.

Hell no, all humans will die from some crisis or big disaster, or maybe the earth will be swallowed by some black hole (Actually it's happening) scientist found out that our galaxy is being sucked by some Massive black hole.\n\nI just don't want to be there when it happens :D

Earth rotates. Sun on one side.

I think we'll screw up the atmosphere, then choke to death.  1000 years later, the Earth will probably fix itself, sans us.

you'd fall very quickly and then go past the centre towards the surface at the other side.\nThen you'd start to fall back to the centre and go back to the other side.\nThis is basically how a pendulum works.\nBy the way.. there should be free fall at the centre of the earth... I.e. no gravity.

They are in space.. so it depends from what angle or where are you looking as a whole picture. Since we are on earth, we take earth's orbit as the reference and draw the other planet's rotation. But from outside in space (outside earth), if you are positioned perpendicular to earth's rotation, then earth is rotating in vertical direction.. thats what i could imagine..

The worst thing that'll hurt the Earth is getting melted by the Sun when it grows from a small yellow star into a red giant star in about seven billion years, as estimated by astrophysical calculations.\n\nThe Sun will  transform all the hydrogen it has into helium by fusion of hydrogen nuclei into helium nuclei. The helium will accumulate in the Sun's nucleus, and the Sun's volume will increase. Its temperature will also increase. As a consequence, In about three billion years, water in the Earth's oceans will evaporate. In about seven billion years, the Sun will ultimately swallow Mercury, and its temperature will be so high that the Earth's rocks will melt.\n\nAfter that, the Sun will have burned all the helium in it and shrink into a white dwarf star, so the Solar System, including the Earth, will freeze.\n\nThat will mark the end of the Earth, and so it will be the thing that will hurt it most.

1. If the Earth's rotation INSTANTLY stopped, everything not fixed to the Earth would continue to rotate around at the same velocity that they were before due to conservation of momentum. To us it would feel like a giant earthquake where the Earth would suddenly start "moving" in the opposite direction of the rotation. Buildings would collapse, the oceans would wash up onto land in large tidal waves, and there would be a large atmospheric wind shear at the surface. (The atmosphere is not attached to the planet either and would keep rotating too). Since we are traveling at about 460 m/s at the equator (about 1000 miles per hour) we would be tossed pretty far. (We wouldn't fly off the earth, though. Escape velocity is much higher.) As my officemate said when I told him about this question "We would be thrown into the wall at 1.5 times the speed of sound as the building was tipped off its foundation." \n\n2. Seismic waves from the impact would travel through the earth causing massive earthquakes. Depending on the size and velocity of the impactor, the earth might even break apart. \n\n3. Much of the atmosphere would be boiled off. A fireball would expand outward destroying material in it's path and polluting the rest of the atmosphere. \n\nThose things would probably kill all life and level everything on the Earth's surface! It would be much worse than the extinction event that may have contributed to dinosaur extinction. \n\nIf we were magically able to stop the Earth with no bad consequences, life on a non-rotating or retrograde (backwards) rotating planet would be very strange. \n\n* On a retrograde rotating planet, the sun and all the stars would rise in the west and set in the east. \n\n* If the rotation was very slow, the day could be very long. This would have a huge effect on plant and animal life on the earth, some of which could not survive many days with no sunlight. \n\nIf there are any physics enthusiasts out there, from knowledge of the mass of the earth, the radius of the earth, the earth's escape velocity (use as impactor velocity), the rotation period of the earth, and the average density of the earth you can calculate a very rough estimate of the size of an impactor needed to stop the earth's rotation. If I assume that the earth collides with an object just sitting in its orbit right at the edge at the equator I get a rough radius of 1600 km for the needed size. In reality, you would probably need something much, much bigger. There are not any objects of this size in the solar system that we don't know about, which means that this scenario can't really happen.

Our sun will expand and engulf the earth and turn it into a ball of molten rock, then vapor.  Run... this will happen in about 5-6 billion years.

Time is unconnected to the Earth.  The only immediately noticeable differences between normal Earth and a backward rotating Earth (NOT counting the moment during which the Earth stops spinning) is that water will circulate in the opposite direction in the ocean, counterclockwise instead of clockwise, and storms will rotate across the Earth in a different directional tendency.

it depends on the exoansion of the universe. if it is expanding too fast for gravity of all the bodies to pull it back together, eventually it will spread out so far that there will be no motion and the entire universe will reach absolute 0 temperature. but, if gravity can eventually reverse the expansion of the universe, everything will be suckiked into 1 black hole and return to a singularity, like it began at the big bang. this will have basically infinite temperature. the first case is ice, the second fire. i think some scientists measured the expansion and they think it will shrink eventually, going back to a dot, but i dont think they were really sure.

Even if the earth stops rotating,it will still be revolving around the sun and each area on the earth will be facing the sun once in a year.That is the sun will be over head once in a year in each place though at an angle from the horizon in some places.Thus one day and one night will approximately be  six months each.Accordingly weather condition may also change which will be anybody's  guess.

No but it would affect existence on the planet! There is a delicate balance to be maintained and if polar ice caps melted, this balance would be tipped over.  You can certainly expect weird weather.
