Massive ice sheets covers whole or part of the Supercontinent. Supercontinental breakup creates the new plates with a severe global warming and rapidly melts the ice sheets, exiting the global ice age period. Breakup and joining of the plates in between two Supercontinental periods causes small scale global warming and ice ages. Mass extinction occurs in the ice age and global warming periods. Evolution takes place in the post global warming period.
Life thrives in the steady moving of the plates or in the period of oceanic plate subduction.
In my 1992 paper presenting the deep hot biosphere idea, I suggested that perhaps 10 planetary bodies in our solar system would provide suitable subsurface homes for fundamentally the same kind of life as we have within the earth. The work draws parallels between previous stages of dynamic development on Earth and those currently occurring at the larger planets. The serious scientist is assured of a stimulating read crossing astrophysics, geology, mathematics, and heat engines. The text is important reading for students researching alternate possible answers to old questions. I began to suspect that there was something wrong with the standard model of Mars a couple of years ago when excitement was building over the Pathfinder mission to Mars.
