There are several models explaining the figure of the Earth. These models vary in the way they are used, in their complexity and in the accuracy with which they represent the size and shape of the Earth. These models are sphere, ellipsoid, and geoid.
Flat-Earthers often take the existence of these multiple models as evidence of disagreement among scientists, and that the shape of the Earth is still in contention. They are wrong. All these models are valid models, only with different complexity and accuracy.

In a talk show, Neil deGrasse Tyson explained the figure of the Earth. He told the audience that the Earth is practically round, but it is a little farther from the center near the equator compared to the poles. And that in the southern parts, it is a bit farther from the center than in its northern regions. To illustrate the fact, Neil used the analogy ‘pear-shaped.’
Flat-Earthers really love to ridicule the ‘pear-shaped’ analogy. But they are mistaken. If they watch the entire unaltered video, they will find Neil explained the fact very clearly.
