Earth expansion and how to falsify it.
I say it's in the obvious category. The Earth has got bigger. Grown.
Which means the surface moves outwards from the centre, and that
crustal break-up and sideways movement of the fragments are a
consequence of adjustment to this outwards movement.
We can easily tell that this has happened from the difference in the
way the crust and the mantle have behaved, which leads axiomatically to
a conclusion that the Earth has got bigger - approximately doubled in
size since the Mesozoic.
Not so easy is telling how to falsify it. What geological acid test
could be used to FALSIFY Earth Expansion? ....how would you assess,
*GEOLOGICALLY*, if the Earth has got bigger? (Or not?) Really
substantially bigger; doubled in size in the last 10% or so of its
history.
This is not a question for homework. This is a serious attempt to
address how we understand global geology.
What would the first question be? Something to do with:-
The way that the crust has broken up?
The way that the crustal fragments have moved?
The way that the plates have grown/ shrunk/ moved/ been created/ been
destroyed?
Much simpler than that. If the Earth is expanding then this could be
directly detected by a lengthening of the diurnal period and by retardation
of the pendulum.

Or maybe about mountain belts, stratigraphic sequence, ..et etc;
anything you like, but always the question must pertain to the geology
(rocks and things of the geological past - not slide rules and gps of
the present).
