The horizon has 0 slope. Horizontal is parallel to the plane of the horizon at right angles to vertical. It's really weird that you keep asking me about tides when I have not made any claims about tides. A 24-hour sun in Antarctica doesn't have anything to do with the ground being measured flat. Just another red herring. Said in Mr Sensible's Video about his flight to Mali.
