Why is earth a geoid?

What is the shape of earth ?
Most people thinks that earth is spherical in shape ,but it is not .It have a geoid shape .

Our planet has this shape due to the centrifugal forces formed due to it's rotatory motion.The north & south poles are flat & it's equatorial region is projected outwards .

This shape is what that makes the equatorial regions warmer than poles.
