Our understanding of the formation of an atmosphere, ocean deeps and mountain highs and the life that thrives on it, mostly relies on our understanding of tectonics on Earth.

Traces of the tectonic evolution of the Earth remain preserved in the geological archives of our planet, the continental cores, cratons.
