because it two poles on the Earth causes it to bugle out in the middle.
It spins on its axis and the centrifugal force makes the part at the equator bulge out slightly.
symtrifical force my friend. as the earth spins, rock, water, everything on the side is pushed outwords as if you spun a rock on a rope around, it would push outwords.
Earth is not a perfect sphere because the rotation of the planet has slightly distorted the shape.
The earth is not perfectly homogeneous either. Continental crust and oceanic crust have different densities and thicknesses. Also, centripetal force from the earth's rotation causes the diameter through the equator to be slightly greater than the diameter through the poles.
well, from space, it is round. but this is the earth you are talking about! up close, you are a molecule! so even though small and round from far away, up close it is so big wherever you are, it is flat. :)
Earth is not a perfect sphere; it is slightly wider across the equator than it is from pole to pole, but that difference is less than a percent of Earth's average diameter, too small for the human eye to notice.
you are part of wich sphere of Earth
No, the Earth is a bit wider than it is "high". The shape is often called a geoid (Earth-like) or an ellipsoid. The rotation of the Earth causes a slight bulge toward the equator. The circumference of the Earth at the equator (24,901.55) is about 41 miles greater than the circumference through the poles (24,859.82 miles. If you were standing on the moon, looking at the Earth, it would be virtually impossible to see the bulge and the Earth would appear to be a perfect sphere. The mathematical name for the shape of the earth is an 'Oblate spheroid'.
Actually, Galileo wasn't the person who discovered that the earth was a sphere.
The earth is characterised by a sphere
Oblate spheroid
The sphere that we all live on is called the Earth. (It is not a perfect sphere, but close enough)
The earth is not a perfect sphere because it is flatened somewhat at the north pole and south pole.
Earth is not perfectly sphere, the Earth bulges at its equator for it is spinning very fast on its axis.

It is pretty close.

Yes, for a suitable definition of "round". It is not a perfect sphere.
A globe is a perfect sphere; the earth is shaped more like a pear.
Ideally, if the earth were a perfect sphere, the gravitational potential energy would be zero. In the center of a sphere all other points within the sphere have an equal and opposite counterpoint. They work to cancel each other out. However, the earth is not a perfect sphere so there would likely be a gravitational pull towards the area with the greatest mass.
