Food for thought. I guess the seas would settle at one level (or
close
to) and stay there.

Nope. Both the Sun and the Moon cause tides, and removing the moon
would still leave the solar tides rising and falling twice a day.

The difference would be that they would always rise to the same
heights.

How big an effect is the solar tide? Doesn't the moon have more
influence?

Yes, much more, since the tide is a function of the NONUNIFORMITY of
the
gravitational field and not the magnitude by itself. Since the moon's a
lot closer, the change of its field with distance is much larger (even
accounting for its overall much weaker strength).

Anybody done any study on the effect of the moon's increasing orbital
distance is affecting tidal behavior?


Until I just looked it up, I thought the Moon was getting closer. But
no, moving away at the astonishing rate of 3.8cm a year.Presumably the
effect would be a weakening of gravitational attraction and lower tides.


...it's seems the universe moves at greater speeds than previously
imagined by either of us.


I wonder if that has any bearing on the theory of the Moon being ejected matter from the Earth?
