SUMMARY

The Earth is not a perfect sphere due to its rotation and the non-uniform distribution of mass. As a rotating body, it experiences a bulging effect at the equator, similar to a spinning ball that is not rigid. This phenomenon is exacerbated by the Earth's composition, which includes varying densities and structures beneath the surface. For a deeper understanding, refer to the provided link discussing centripetal forces and their impact on planetary shapes.

PREREQUISITES
  • Understanding of basic physics principles, particularly centripetal force
  • Familiarity with planetary geology and Earth's internal structure
  • Knowledge of rotational dynamics and their effects on celestial bodies
  • Basic comprehension of the concept of hydrostatic equilibrium in planetary formation
NEXT STEPS
  • Research the effects of centripetal force on planetary shapes
  • Explore the concept of hydrostatic equilibrium in celestial bodies
  • Learn about the Earth's internal structure and mass distribution
  • Investigate the differences between oblate and prolate spheroids in planetary science
USEFUL FOR

Students of physics, geologists, astronomers, and anyone interested in the scientific explanations behind the Earth's shape and its physical properties.

Why is the Earth not perfectly round
 
Earth sciences news on Phys.org
if you spin a ball that is not perfectly rigid, it bulges outward slightly at the spin equator. If it were made of jello, it would bulge out quite a lot.
 
The distribution of mass on Earth is not constant, altering the shape of the earth.
 
Thanks.
