La formation des premiers continents a fait l’objet de débats. L’analyse des zircons au Canada et en Australie suggère que ces processus historiques sont similaires aux mouvements tectoniques actuels.
How the earliest continents formed has been a matter of debate. Analysis of zircons in Canada and Australia suggest that those historical processes are similar to current tectonic movements.
Layers of rock provide a historical record of variations in the Earth’s orbit, revealing information about the planet’s climate billions of years ago.
