tectonics

The oxygen event (initial uplift from near zero at 2.3Ga) is not directly related to plate tectonics.

Remember, in the 1950s the new theory of plate tectonics was only just coming into wide acceptance.

If there is no plate tectonics then all the CO2 gets locked up in carbonates and the temperature falls (e.g.

Underwater sounds can come from a wide range of sources, including tectonics, natural events and animals.

How would you create the conditions necessary for supercriticality given only plate tectonics, an atmosphere, multiple asteroid impacts, and liquid water?

It does not make much sense in terms our understanding of tectonics (or lack thereof) for other bodies in the solar system.

You could apply the same logic you're using for plate tectonics to the shape of the Earth, which is Asimov's main example.

It has been a warm time, when temperature has mattered as much as tectonics.

This is the same as the example Asimov gave thou, plate tectonics being that the surface of the earth moves at imperceptible rate.

It is plate tectonics that have kept earth in the habitable zone.

The cheapest clean energy is actually geothermal, but there are only so many places where the plate tectonics work with our current drilling technology.

I do not know why but volcanoes and tectonics were intrinsically linked in my thinking.

So it's not like the "plate tectonics" examples changes anything in his argument.
