Question

why earth is not 100℅ round like circle?​

Answer 1

Answer:

Earths rotation causes it to be flat at the poles so it is not round

Answer 2

EXPLANATION :- The Earth is massive enough that the pull of gravity maintains its roughly spherical shape. Most of its deviation from spherical stems from the centrifugal force caused by rotation around its north-south axis. This force deforms the sphere into an oblate ellipsoid.
