Answer:
The Earth is an oblate spheroid, bulging out slightly at the poles
Explanation:
- Earth's surface structure is in the form of geoid of three-dimensional structure. As the earth's topographic features are associated with landform and water bodies.
- Hence earth is not a complete sphere nor a perfect sphere its a form of oval-shaped epllicics and thus has an ellipsoid revolution and a tilt around the sun on its axis.
- The bulge at the equator is a product of the spinning of the earth and modern geodesy takes this ellipsoidal as a spheroid.
I think the correct answer is crust. I am really sorry if I am wrong.
