Excellent work. Hmmm, red dwarf star? It would be orbiting close, and that might partially account for the lack of major continents- the world is 'boiling,' so to speak, and all those hot spots are convection in the mantle.

It orbits closer than Earth does to the sun, yes, but that doesn't make it "boiling," as red dwarf stars are cooler than the sun. It lacks major continents because it accumulated more water during its formation. In fact if it weren't for the volcanic activity this would likely be a complete water world with no land whatsoever. The volcanic hot spots are caused by tectonic activity, much like on Earth, except without continents the interaction of plates creates islands rather than mountains.

Well no, that was not what I mean. Look at Io orbiting Jupiter. It has a lot of volcanic activity due to being right down in the intense magnetic field of the gas giant. I was suggesting that a similar situation with close proximity to the red dwarf would cause a lot more convection in the mantle; it is only 'boiling' in the sense of that convection, which might explain why continental plates never formed.

Io has volcanic activity from tidal forces, it has nothing to do with the magnetic field. The gravity of Jupiter and the other moons pull on it from all directions, which creates enough friction to cause volcanism in Io's crust. The only thing the magnetic field affects is radiation. Continental plates did form on Calusa, but because there is so much more water on the planet only the mountain ranges formed by their interaction reach above water, forming islands.
