Astronomers from the Technical University of Berlin, the German Center for Aviation and Cosmonautics and the Wilhelm University of Westphalia (FRG) have shown that on Earth and similar planets, under certain conditions, conditions suitable for life can exist without tectonics.
Scientists have modeled the processes that take place in the upper layer of the mantle, planetary crust and atmosphere. Experts were interested in the accumulation (over 4.5 billion years) of water and carbon dioxide on an earth-like celestial body in orbit around a sun-like star. If the planet is at a distance of one astronomical unit from the star, liquid water can be present on it even without active tectonics. The width of the habitable zone at the end of evolution was determined by the content of degassed water and carbon dioxide in the planet's interior.
Tectonic activity (the existence and movement of lithospheric plates) in the solar system is observed on Earth, some of its elements are allowed on Mercury. Also, analogs of tectonics, possibly, are found on celestial bodies with liquid or frozen subsurface oceans.
