Now, I can apply some math to this Snowball Earth for we know life exploded in the Cambrian, after the Snowball Earth, and we can calculate roughly how much oxygen was needed to allow this Cambrian life explosion. We can estimate how much life in the
seas existed to create that oxygen.
And with good calculations we can calculate how much water was in direct perpetual sunlight to create a Cambrian Life Explosion.
It maybe the case that the Oceans were on the perpetual sunlight face and Rodinia supercontinent was mostly all on the perpetual dark side of Earth.
Now I would like to, and wish to go far into that above calculation, but most of the numbers data are known by only a few experts if known at all, in remote fields of biology and geology, and chemistry. Such as how much oxygen does phytoplankton produce
per year?
How much oxygen per year is required for a animal of a certain size to live per year?
Then a enormous amount of data as to how much oxygen in the atmosphere in cubic density for animals to live per year.
Enormous number of assumptions to pick through. One in particular was whether oceans took up 70% of Earth surface with continents the rest-- 30%.
Is it possible in the end to form a reasonable table of numbers?
Then calculate if the Continents were on the perpetual sun side of Earth to render a Cambrian life explosion, or were on the perpetual dark side of Earth.
If history in past life in the age of dinosaurs is to go by-- the continents were on the perpetual sun side for dinosaurs lived near North pole and South pole and all in between in the warm perpetual sunlight.
But the question is, with no life on land, or little to no life on land, did the oxygen making phytoplankton in the oceans have the perpetual Sun side of Earth , or only the 50-30 = 20% of oceans on the perpetual sun side? If the phytoplankton were on
the perpetual Sun side, they could build up that oxygen atmosphere. But if the phytoplankton had only 20% ocean of perpetual sun side, much more difficult to make a oxygen atmosphere.
I am going to go out on a limb of guessing, that the Cambrian Explosion of life was because of the oxygen enriched atmosphere due to the oceans were in the perpetual sun side of Earth while the continents were in the dark, perpetual dark side of Earth.
And it would be easy to have a snowball Earth if the continents were on the perpetual dark side.
And then in Continental Drift of Rodinia to Pannotia supercontinent finally making its way back to the perpetual sun side of Earth ushering in the Cambrian Life Explosion.
