the equatorial diameter or the polor diameter

The equatorial diameter since if you think of it, the Earth it not perfectly round. It's actually "fatter" than it is "taller". Another reason is because the rapid speed of the Earths rotation in centrifugal force.

The equatorial diameter.

Equatorial. The Earth is an oblate spheroid. That means it is roughly spherical, but flattened at the poles. This is due to the centrifugal force produced by the earth's rotation. You can see this in other planets as well, most notably Jupiter and Saturn, which have, for their size, extremely rapid rotation periods.

The equatorial diameter is bigger due to the rapid speed of the Earths rotation in centrifugal force.

The earth is an oblate spheroid. The diameter at the equator is slightly bigger than at the poles.

Equatorial radius 6,378.137 km
Polar radius 6,356.752 km
Mean radius 6,372.797 km

the Earth is "wider" than it is "tall", so the equator is longer
