Good point. Is there a perigee/apogee effect as well I wonder? (similar to
the effect on the Jovian moons)

The specific heat of seawater, although varying with salinity,
temperature, and pressure, is somewhat lower than that of pure H2O, more
like 0.95 cal/gC° (3.9 J/gK).

Yes there is a perigee/apogee effect but that is one of the components of
libration, so it isn>t "as well". The moon is a little egg shaped because
of the tidal effect. When it gets closer to Earth it gets more egg shaped

By while the earth is rotating, the moon always shows the same face to

The lunar tide due to the Sun would probably cause more dissipation,

it will still be small.

Technically speaking, the moon has a "static tide". Although some
might say
that is an oxymoron. However, there is a still a tidal potential that
affects the moon and therefor a tide, static or not.
But indeed, since the tide is static there is no flexing, hence
no heating

By while the earth is rotating, the moon always shows the same face to

The lunar tide due to the Sun would probably cause more dissipation,

it will still be small.

This topic is entirely Selene/moon related, such as the supposed
volcanic or lava fused as little and apparently not so little basalt
and silica combined spheres (�green glass spherules�) that researchers
claim to be of their NASA/Apollo moon rock samples, that which
supposedly their spendy (public owned) mass spectrometers as having
only recently detected as containing 260,000 ppb of good old h2o.
(that>s not necessarily per given mass of common moon bedrock, but of
the given mass of each little portion of rock containing such lava
formulated geodes as solid glass spheres that could have been
contributed and/or contaminated by most any icy meteor encounter)

The tidal flexing, as you call it, only affects the Earth>s oceans. It is
far too puny to affect the landmass. The Earth has no tidal effect on the
Moon, since its rotational period coincides with its orbital period. No
flexing there, Guthball

Sorry.. the discussion above was about the moon. And thats what I
was talking about.

beats me. I was talking about the moon.
