1. Would ocean tides exist if the gravitational pull of the moon (and sun) were somehow equal on all parts of the world? I know it's no but why?
2. With respect to spring and neap ocean tides, when are the lowest tides? That is, when is it best for digging clams?
3. The human body is composed of mostly water. Why does the gravitational pull of the moon overhead cause appreciably less biological tides in the fluid compartment of the body than the gravitational pull of a 1 kg melon held over your head?
