Details I Missed On Avalon

Chapter Three

Equatorial diameter: 11,308 kilometres. Highest Andromedan peak: 4500 metres. Corona, the north polar continent extending past the Tropic of Swords: eight million square kilometers, comparable to Australia. In the Southern hemisphere, Equatoria, New Africa and New Gaiila are small continents or large islands.
-copied from "Who Knows Of Avalon?" here.

I missed some details:

Avalon's molten core is smaller in proportion than Earth's;

the planet's 0.635 mass cannot store as much heat;

therefore, mountain-forming forces are weaker;

erosion is faster;

atmospheric pressure, similar at sea level, drops more slowly with height because of the different gravity gradient;

rapid rotation causes violent weather;

therefore, the surface is low - the highest Andromedan peak only 4500 meters (see above);

there are no great land masses;

the only real continent, Corona, is eight million square kilometers, the size of Australia (see above);

the Southern land masses are more properly called large islands;

otherwise, there are only smaller islands;

however, one gigantic feature is the Oronesian archipelago, a submerged range with peaks rising above the ocean surface, described in the next paragraph of "Who Knows Of Avalon?"
