Why is the world round?
442513
The gravitational force holds it into a spherical shape.

because the sun's gravitational pull is much greater than the earth's...same reason the moon goes around the earth and not the other way around

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.

The earth is round and its gravitational pull draws us to its center.  Upside-down is really just pointing away from the core...from anywhere.

Columbus was challenged by the Spanish government, specifically the Queen, to disprove the commonly accepted  notion that the world was flat.  Conceptually, the formulation of his proof that the world was indeed "round" (spherical, or possible cylindrical - it's not specified in history texts what "round" meant to Columbus) was that if he could set some starting point and then sail around the world in a constant direction, should he return to his starting point then his theory would be proved.\n\nHe ended up in the Indies, which has ever since been named the "West Indies", but thought he was elsewhere.  As far as Columbus was concerned, he was sure that he had found some one of the outermost islands of Cipango or Japan. So he dropped his anchors, ordered out his rowboat, and prepared to take possession of the land in the name of the queen of Spain, who had helped him in his enterprise.\n\nOf course, he wasn't in Japan or Cipango...if you want a full text detail of the story, follow the link in references...this was the short version.\n\nI hope this helps you!!

columbus sailed west to the indies instead of going around africa because he thought it would be faster. most people those days believed the world was flat, but columbus thought the world was round. he went west, but ended up in north america, but he didn't know that. he called the people he saw there indians because he believed he was in the indies.

It seems flat to me.  However, when I peer intently  at lines of clouds over a real-long horizon I detect a curl this way and that, like it's following some sort of curvature of the surface in a distant kind of way.  It's really spooky.  But you include the question "Was it ever round?"  So if you want more on the subject, listen to Phil Hendrie on xm radio channel 152, and sometimes he has a guest General Johnson Jameson, who attempts such inquiries.  As an added bonus, a few conversations about a society of small people who live in a magical land.

It means that sometimes the needs on one man are lost in the need for the greater good of mankind.\n\nThe Earth is round because

money makes the world go 'round.

Neither.  It is more of an oval thanks to the strong magnetic pull at the *top* and *bottom* (North and South Poles) of the earth which also have to do with gravity.  Were these features any different, the fowl of the air would not know where to go in the winter.

Because the circle, in its every form, is the most marbelous shape in the universe.  It really is when you think about it.....

I think the world is round. Have you been outside of your room even? If the world was flat, you would be flooded, he he. Why are there mountains if the world is flat? Really you can't even answer my question? Try going to the library and actually do some research. Gotta go. Rock.

so that they roll. why are wheels round?

you know the world isnt flat right??

The earth is APPROXIMATELY round due to gravitational forces.

I'm going out on a limb here, but I would say round.  The reason I say round is this.  Way back when, everybody thought the earth was flat, until someone sailed around the world.  What I don't get is the fact we can look up at the sun & moon, and it's plain to see they are round.  Why in the world would those people ever thought the earth was flat, I'll never know.  We are like fish in a bowl, we can see out but can't live out there.  As of now it is impossible for us to ever go that far out of the bowl without it killing us.  I don't think we will ever know the answer to that question, at least not in our lifetime.  Think about it, we can see into the past, and see things that has taken place millions of years ago.  Can we somehow see the other direction, and look into the future?  Maybe!  I too am fasinated by the universe, and wish I had answers to these questions, but since we are so tiny when compared to the universe, I wonder if we are not just a molicule of some giant living thing thats waiting to crawl off.  \nHave Fun.  Good Luck!!!

It's just an assumption...\n\ncoz it looks like a sphere... like how the moon looks round...\n\nBut can u be sure!!!
