Reply to comment by ventus1b in If earth was a smooth sphere, which direction would water flow when placed on the surface? by Axial-Precession

If it's placed at rest relative to the ground then it would flow towards the equator.

If it's placed at rest relative to the center of Earth and we could magically avoid any friction (no surface can do that completely with water) then it would just spread out.

Yes, thanks for reminding me of that distinction.

I was thinking of water at rest wrt to Earth. Or both at rest and Earth spinning up.
