Expanding Earth /  
The Evidence:
1. Young Oceans.
As predicted by expanding Earth theory, all current seafloor
in the world is young (less than 200 million years old.)  
This was not expected given the conventional
view of the time: continental fixism.
2. Matching Trans-Pacific Outlines.
The continental outlines that bracket each ocean, Pacific
included, fit together like pieces of a puzzle.
3. Trans-Pacific Biotic Disjunctions
The regions that interlock along matching outlines (New
Zealand - South Chile; Tasmania and South-central Chile,
etc.) share hundreds of poor-dispersing sister taxa found
nowhere else in the world.  The distributional problems
created by the hypothesis of a now vanished pre-Pacific
superocean are overwhelming. The webpage link above
focuses on this evidence.
6. Successful expanding Earth predictions vs.
post-hoc plate tectonic explanations.  
While many "surprising" geophysical
discoveries were predicted by expanding
Earth theory, plate tectonics has had to
develop new hypotheses  to explain the
problematic observations.
5. Simple Geometric Problem
In the Cretaceous, both the Pacific plate and South
America were connected to Antarctica.  Since that time
North America and its Bering region has moved away
from South America while South America has moved
away from Antarctica, requiring that the distance between
Antarctica and the Bering regions is greater today than in
the Late Cretaceous. The Pacific has expanded north-south
since that time. It has not significantly contracted as static
radius assumptions require.
4. The Dinosaur Circuit
Even in conventional reconstructions of the Late
Cretaceous, North America and East Asia were
connected by the Bering bridge while South America and
Australia were both connected to Antarctica. During that
same time, a great number of terrestrial taxa including
the largest of dinosaurs moved between South America
and North America -- and Australia and East Asia.  This
requires direct terrestrial connections completely around
the Pacific, confirming its smaller size.
