The Earth's Shifting Crust by Charles Hapgood - wire of information

EARTH'S SHIFTING CRUST
include the following: whether we have properly estimated
the magnitude of the centrifugal effect; whether there is any
layer below the crust weak enough to permit crust displacement;
whether the Antarctic icecap is really growing, as the
theory requires, or is in retreat; whether the centrifugal effect
we postulate would not in practice merely cause the icecap to
flow off from the Antarctic continent into the sea, rather than
transmit its push to the crust; whether the thrust of the ice-
cap, if it was transmitted to the crust, would be transmitted to
the crust as a whole, as the theory requires, or would be ab-
sorbed in local readjustments of the crust; whether, if both
the poles happened to fall in water areas, icecaps
would not
cease to develop, and thus the whole process of crust displacement
be brought to an end; why, if crust displacements have
been frequent in geological history, there are not evidences
of more icecaps in the geological record; why, with that assumption,
we find some rock formations that appear to have
been undisturbed since the earliest times. All these objections,
and many more, are fully, and I hope fairly, discussed
in the following chapters. Therefore, if the reader finds him-
self asking questions that do not appear to be answered, I
hope he will have patience. He may find that they are answered
in later parts of the book.
