what is the real shape of the world?

Question

i have hear the shap of the world is really egg shape is this correct

Answer 1

When people say egg shaped or pear shaped they are technically correct. However the amount of deviation from a perfect sphere is very small so if you were in space you wouldn't notice it at all.

Answer 2

The earth is slightly bulged at the equator and flattened at the poles from a perfect sphere. I believe the deviation is about 20 miles. It's called an oblate spheroid. NASA has launch sites near the equator to get the extra boost from the speed of rotation of the earth (faster close to the equator) not because of the altitude.

Answer 3

The earth is indeed slightly elliptical with the equator bulging out slightly in repsect to the rest of the planet. This is because the centripetal acceleration of each longitude approaching the equator is greater than the one before it (the radius of each longitudanal disk increases while its rotational velocity is constant throughout the earth). Thus the earth bulges where its centripetal acceleration is greatest, the equator.

Answer 4

The earth is a sphere, slightly bulged (by a few feet) at the equator. Just look up some photographs taken from space.

Answer 5

No it is not correct. Earth’s shape is called geoid=the slightly flattened sphere , used in calculating the precise measurements of points on the Earth’s surface.

Answer 6

The shape of the earth is a very slightly deformed oblate sphereoid. The shape has a special name: Geoid.

Answer 7

In a way,yes.The bulge at the equator is real but mostly insignificant.All spinning objects get slightly distorted by centrifical force. But it is significant enought that NASA would like to have launch sites at the equator.It means less distance to travel to get into space and burn less fuel to get there.

Answer 8

not really but still there is some conical attribute of a egg like shape having less ecentricity

Answer 9

it's a sphere
