What do mean by the word oblate spheroid I know it's the shape of

Dear student,

Since the Earth is flattened at the poles and bulges at the
Equator, geodesy represents the figure of the Earth as an oblate
spheroid
The oblate spheroid, or oblate ellipsoid, is an ellipsoid of
revolution obtained by rotating an ellipse about its shorter
axis
