Eli5, if the earth isn’t perfectly round, why does it seem that way in pictures from space?

Question

I’ve always asked this question but people don’t really know or just answer in ways I can’t really understand it so I was just wondering if somebody here knows why?

Answer 1

Because it’s only very slightly oblate. Earth’s diameter at the equator is only 43km larger than at the poles, which is just about 1/3% of Earth’s diameter.
