It should also be noted that the sphericity of the Earth only applies on a macroscopic scale; the hills and valleys don't seem to spherical to me ;)
That's because you're working on a relatively tiny scale. If you were to scale up a billiard ball (which is smooth enough to be a clichéd comparator) to the size of the Earth, guess which would end up being smoother?
Oh, and did anyone mention the fact that the sphericity of the Earth is distorted by the tides?
