Default Moments of Inertia and the Shape of Continents and Landmasses on Earth

On Jul 2, 8:21*pm, Chris L Peterson

The planet's geological circumference is 24 901 miles at the equator
which makes 15 degrees of geographical separation equal to 1037.5
miles.Come back to the thread when you learn that the equatorial Earth
turns at a rate of 15 degrees/1037.5 miles an hour and a full
circumference in 24 hours.

You might even have a chance to comprehend the uneven rotational
gradient between equatorial and polar latitudes in the rotating fluid
interior which is responsible for the 26 mile spherical deviation
between equatorial and polar diameters and consequently the lag/
advance mechanism for crustal generation off the Mid Atlantic Ridge.

An astronomer takes the observation that rotating celestial bodies
with exposed viscous compositions display differential rotation hence
to exempt the Earth from this feature takes quite an effort.The joys
of astronomy reside in piecing together cause and effect hence the
neat meshing of the Earth's magnetic field,spherical deviation and
plate tectonics using a single mechanism as the highest probability of
success.

What can be said for a geological community that can't comprehend the
primary geological fact of a round and rotating Earth with values
attached - forget 'climate change',this is where the real issues
exist.
