Some, yes. The coriolis force certainly is provable, and the effect observed on earth is characteristic of a spherical rotating reference frame.
however, "The earth would travel faster than the speed of light, therefore, the earth is round.
Gravity is exactly the same thing as the electromagnetic force, therefore the earth is round, QED. " obviously are invalid arguments because they make illogical and/or wrong assumptions, i.e. Gravity is not the same as the EM force.
