are different constelations seen  from the opposite side the earth?

Yes, they are. However, (Oh God, I can't remember what movie it was, but) The little dipper can't be seen because it is too close to the equator if you are in Tailand. And, I just remembered the movie!!! It was in Bridget Jones, The edge of reason. (I just watched it again yesterday!! LOL! I think Renee Zelwigger is awesome!)

don't lagph but i think that there parrell uniiverses out there one that just so happens to have our opposite on them.

I suppose it depends on what you mean by the 'other side'. \n\nDo you mean directly behind the sun, from our vantage point in space on earth? \n\nWell, there is the abstract answer, then there is the scientific one.\n\nThe 'bizarro-world' answer is that no one knows what is on the other side of the sun, because no one has been there, if we are talking about the side of the sun that is obscure to us. \n\nThere could be anything back there.\n\nBut, there probably is not anything lying close to the sun, if that is what you meant. The sun's surface is 6000 degrees centigrade. And the solar corona, the outer atmosphere of the sun, is one million degrees. Hence, nothing that we know of could survive in those conditions.\n\nUnless you meant the other side of the sun, in terms of the same distance away from it as is the earth. \n\nProbably, from a scientific standpoint, there is just empty space behind the sun. Space is very empty, and vast beyond human understanding.

1. Eclipses, and lunar phases. \n2. The other "celestial" bodies, like the sun, moon and planets also appear round. One might assume, that the earth might be also.  \n3. Gravitational laws based on the earth being a certain shape and size, predict movement, etc. \n4. The stars in the southern hemisphere are  different than in the northern hemisphere.\nIf the earth was flat, one should be able to see the all of the stars at least some of the time. \n5. Sailors regularly circumnavagate the earth.\n6. Planes regularly fly around the world.\n7. The seasons and the climatic zones are hard to explain otherwise. \n8. The coreolis forces of hurricanes.\n\nOne can use scientific method to prove all of these and come up with conclusions for an earth that is somewhat round in shape, if one isnt lucky enough to see it from space, and believe it with your own eyes.

If you were to go a million miles (or so) over the north pole, you'd see the earth rotating counterclockwise, the moon revolving around the earth counterclockwise, and the earth moving counterclockwise around the sun.  \n\nIt is the earth's counterclockwise rotation that makes the sun seem to rise in the east and set in the west.

I know how it will look.  The same side of the moon always faces us because its rotation rate and revolution rate are both the same - 27 to 28 days depending on whether you are looking at it from sidereal or solar time (that's technical lingo you can skip over).  But those two rates are tidally locked and there's no reason that would change.  We'll never see the other side from earth. One thing that WILL change is that is has been, and will continue to, slowly move farther away from us every year.  In the distant future it will appear smaller in the sky and will take a longer time to go around us, 30+ days in the future.  This is because conservation of energy and conservation of angular momentum must both be conserved.  I can explain that, but trust me, you don't want me to.

Nope. \nThere is some evidence that people can sense the magnetic field of the earth and tell which way magnetic north is. But as for true north no one can do that without knowing the magnetic variation for the location they are at.\nWell if you know the time of year and about where you are you could tell true north from the stars but that would be about the same as knowing the magnetic variation for your location.

The Earth and Mars do not orbit the sun in perfect circles, they are ellipses.\nSo sometimes the Earth is closer to the sun than other times, and sometimes Mars is closer to the sun than other times.\nSo if the Earth is farther from the sun than normal at the same time Mars is closest to the sun, and this happens when both planets are on the same side of the sun, then we are closer to Mars than any other time and therefore we can see it better.

The direction that a clock goes is entirely dependent on how it is made.  You can easily put the numbers in the opposite direction above the equator and have it work, so which side of the equator it's made on doesn't really matter.

Two possibilities not previously mentioned: first, phone your various friends around the world, and ask them the time! You will then find out that the sun is at a different height in the sky at different places. So at least the world is not flat, since the sun is very much farther out than the distances between any two points on earth.\n\nSecond, wait for a lunar eclipse. This is the Earth's shadow projected on the moon. It is round. The Earth is not a disk (see first experiment) but casts a round shadow: a sphere seems indicated. In fact, it is a sliughtly flattened sphere (ellipsoid, in fancy language)

Although the earth is rotating in the same direction the angle of incidence is the opposite of that in the northern hemisphere. as the earth rotates the angular momentum causes the water to spin. Think about wheels placed against the surface of the earth and angled so that their axles are pointing at the center of the planet as the earth rotates they will turn in opposite directions.

First I want to clear up that clockwise is really a 2-dimensional description of rotation, and planet rotation can be viewed in 3D so you can't really describe planet rotation as clockwise or counterclockwise. If you define an "up" and a "down" for the solar system, and then say "when viewed from above the solar system rotates counterclockwise", then the "anticlockwise" description works. For my answer we will assume you have done all this and that the solar system rotates counterclockwise, so there is no confusion from the wording of the question.\n\nThe reason the solar system rotates counterclockwise has to do with the way the gas clouds that created the solar system collided. They didn't collide head on. Think of cars travelling in opposite direction down an interstate hitting each other not quite head on (i.e. the left headlights of both cars smack together). When they do this they will spin out sideways - they will effectively rotate around each other (in North America with the cars driving on the right side of the road, they will rotate counterclockwise when viewed from above if they collide like this). The gas clouds did the same thing and their collision exceeded the critical density needed for gravity to take over and start forming the solar system, and as this matter collapsed to form the sun and planets, the rotation sped up. The rotation these gas clouds got from their collision gave momentum to the rotation of most matter in the solar system; the sun rotates in the same direction as those clouds did when they collided and so does most other things, including all the planets.\n\nSo that is why.

The direction of the north magnetic pole on the earth changes slowly over time. In addition, occasionally, the north and south poles reverse with the pole in the northern hemisphere becoming a south magnetic pole and vice versa. This can be recorded in magnetic rocks and even has utility as a dating method. According to our understanding right now, we are in the middle of such a switch. This is why the strength of the magnetic filed is decreasing. Anyway, a shift is when one of these switches happens.

The earth has two magnetic poles, a north pole and a south pole.\n\nThe effect of both poles can be detected by a good compass from anywhere on earth.

Have you ever noticed that the sun appears to come up on one side of the horizon, and then several hours later it seems to sink down on the other side of the horizon?\n\nIf you ever noticed this phenomenon, you were aware of the Earth spinning.

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.

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.
