Same as all other planets are round...I learnt in school that its something to do with gravity in the center of the earth...everything is pulled inwards towards it evenly, so the most even shape u can have is a circle

Can't BELIEVE there are people responding that the Earth is round because of God. Religious folks just cant answer a question without raising more difficult ones, can they?
Oh well. Its round because of gravity. You might as well ask why Jupiter is round and why the sun is round. If the reason was that 'God did it' why dont those same detestable theists explain WHY God picked a sphere and not a dodecahedron which would really prove God existed since the laws of nature couldnt make something so insipidly stupid.
However, I digress - they're all spheres because gravity is acting equally on it. In fact, the heavier the planet the more closer it will be to a perfect sphere. Only very small 'planetoids' and smaller asteroids lack the gravity to make them spherical - though of course they do have their own gravity - just as the Earth is exerting influence on me with its trillions of tons I am pulling on the Earth with my 90 kilos. Earth wins because its heavier... still maybe one day I'll fly!

The answer is gravity. The Earth is thought to have formed four-and-a-half billion years ago, from a huge, rotating cloud of gas. In the newly born Earth, gravity pulls from the center. Parts at the same distance from the center are pulled with the same force, and ends up with a spherical shape.

The roundness of Earth is not equivalent to perfection.So the roundness of Earth is also a necessary illusion, better than the flat one.The earth is geoid.

The earth isn't round. The rotation causes the poles to flatten. (If the earth weren't rotating, it would be a sphere. But do you know how impossible it would be for the earth not to be rotating? Relative to everything in the universe it would be stationary. But I digress...)
The earth is in the shape of an oblate spheroid. (A sphere flattened on both poles.)

Gravity.
Gravity pulled debris orbiting the sun 4.567 bil. years ago together to form the Earth. The mass got large enough that in order to maintain a relatively stable shape, it formed a round shape (not quite spherical due to the spin)

Easy. The Earth is round so that penguins and polar bears don't fall off a sharp edge and land up on passing satellites!

Its own gravity pulls it round.
P.S. Earth is not totally round.

the earth is not round. its what the government wants u to think. think about it. everything u see is fake the moon that comes out at night the sun that comes up in the morning.

Some still believe it's flat. But roundness makes sense, it holds itself together. But hey... what an amazing world we all live upon. The grass is green because of the blue sea and the yellow sky. AMAZING!!
