Is the distance from North to South poles of the Earth equal that from West to East poles ?
Thank you, I'm really sorry about the polesDanger said:Welcome to PF, SiTuCrois.
There are no 'east' or 'west' poles. If there were, however, the distance between them would be greater than the distance between 'north' and 'south'. The Earth is oblate, rather than spherical, due to its rotation. It's a lot bigger around side-to-side than it is up-and-down.

But why does rotation make its side-to-side bigger ?
The distance from the North to South poles, also known as the Earth's polar diameter, is approximately 12,713 kilometers (7,900 miles).
The distance from the North to South poles is significantly shorter than the Earth's equatorial diameter, which is approximately 12,756 kilometers (7,926 miles).
The distance from the North to South poles is an important measurement in geography and geodesy, as it helps to determine the Earth's shape and size.
The distance from the North to South poles has not significantly changed over time, but it may vary slightly due to factors such as polar ice melting and tectonic plate movements.
The distance from the North to South poles is measured using a variety of methods, including satellite imaging, geodetic surveying, and mathematical calculations based on the Earth's curvature.
