Why is earth not a perfect sphere or it is also known as a oblate spheroid or geoid give its measurements equatorial diameter and its polar diameter
answer in brief

hey mate!
The Earth is not a perfect sphere.
Scientists have unveiled the most accurate map ever produced of the Earth’s gravity. The map is called a geoid, the result of two years of orbital surveys by the European Space Agency (ESA) Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite that also studies ocean circulation and the movement of ice.
The geoid is a map of the Earth’s gravitational field and since gravity impacts things like sea level and currents, it’s important to understand how it varies.
This information is particularly important to understanding sea level rise. Scientists predict that, on average, sea level will rise 3 feet overall by 2100, but those three feet will be distributed differently throughout the world.
As you can see, the map shows the Earth is not shaped not like a sphere but a potato.
The reason why our planet has this weird shape is because the Earth’s gravity isn’t uniform. Our planet is affected everyday by such factors like winds, currents and tides, so because gravity is higher in Iceland than for example in India.

earth is not a perfect sphere, it has bulgy sides on equator
