The earth is not really round. It is more close to an oblate spheroid, although the precise shape (the geoid) varies from this by up to 100 meters (327 ft). The average diameter of the reference spheroid is approximately 12,742 km (more roughly, 40,000 km/Ï). The rotation of the Earth causes the equator to bulge out slightly so that the equatorial diameter is 43 km larger than the pole to pole diameter. The largest local deviations in the rocky surface of the Earth are Mount Everest (8,850 m above local sea level) and the Mariana Trench (10,924 m below local sea level). Hence compared to a perfect ellipsoid, the Earth has a tolerance of about one part in about 584, or 0.17%. For comparison, this is less than the 0.22% tolerance allowed in billiard balls. Because of the bulge, the feature farthest from the center of the Earth is actually Mount Chimborazo in Ecuador.

of course it is! as a whole the earth is a massively large sphere but of course there are the mountians and valleys on top of the sphere. Galileo proved this with his pendulum experiment. He suspended a weight from a long string attached to the ceiling, then around the base of the pendulum he placed twelve dominoes. He set the penulum swinging and as the earth turns underneath the pendulum it knocked over each of the dominoes in succession.

Yes, the earth is round, as are the other planets.

No the earth is not round it's like a 3D oval and here is my biggest proof if you know the seasons happen because the earth is tilt so if it wasn't tilt the seasons won't accur every region will have the same seoson billions of years with no change

The Earth is oblate spheroid, and this deviation from a true sphere is due to the planet's spin, which minimizes the effects of gravity at the equator.

More or less, its gravity exceeds the strength of its constituent parts, so it takes on a rounded shape. A very old rocky planet may (it is believed) take on a more egg-like shape at extreme age due to imperfect balance in its rotation.

Not perfectly round....it's a little bit flatter between the North and South Poles than it is at the equator.

kind of. It's not perfectly round. The circumference is longer around the equator than the poles.
