eon w historii Ziemi

AI overview

The Proterozoic is the longest division of Earth's history, lasting roughly two billion years and occurring between the Archean and Phanerozoic eons. It matters because understanding this vast span of time helps scientists piece together the deep history of Earth before the emergence of most visible life forms that characterize the Phanerozoic eon.

Proterozoik (algonk, eozoik) * w sensie geochronologicznym: drugi eon w dziejach Ziemi, młodszy od archaiku a starszy od fanerozoiku. Proterozoik trwał około dwóch miliardów lat (od około 2,5 mld do 542 mln lat temu). Dzieli się na trzy ery: paleoproterozoik, mezoproterozoik i neoproterozoik. * w sensie chronostratygraficznym: drugi eonotem, wyższy od archaiku, niższy od fanerozoiku. Proterozoik dzieli się na trzy eratemy: paleoproterozoik, mezoproterozoik i neoproterozoik.
