Diameter through the poles:7901 miles. Diameter "through" the equator: 7926 miles. So the earth is 25 miles wider than tall.

Centrifugal force pushes every thing away from the centre of a rotating body. The Earth is a rotating body around the North-South axis, thus everything is being pushed away from the axis ever so slightly. It is being pushed enough to cause the shape of the Earth to look like a sphere being squashed at the poles, again ever so slightly.

No, There is Legend from Sumer about the Earth being larger and orbiting in a different location in space. The legend goes on to say that a large planetary body(or good sized moon) struck the earth and caused extensive damage. In its new orbit the Earth was positioned closer to the sun. The surface water melted and massive volcanic activity caused the continents to form and slide, thus repairing some of the damage. That is why some say, the Earth bulges and is not round. Remember, this is only legend.

Earth, however, is not perfectly round. Earth's spin causes it to bulge slightly at its middle, the equator. The diameter of Earth from North Pole to South Pole is 7,899.83 miles (12,713.54 kilometers), but through the equator it is 7,926.41 miles (12,756.32 kilometers). This difference, 26.58 miles (42.78 kilometers), is only 1/298 the diameter of Earth. The difference is too tiny to be easily seen in pictures of Earth from space, so the planet appears round This is from NASA

Yes, you can see satellite pictures of it. Also how do you explain rotation and translation movement?
-
not absolutely round but closer to round than say, egg-shaped.
