What is the name of the first super continent that formed at the end of the Proterozoic eon?
The first supercontinent that formed at the end of the Proterozoic eon is called Rodinia. It was formed around 1.3 billion years ago and eventually broke apart around 750 million years ago.
What was the longest era?
The longest era in geologic time is the Precambrian era, which lasted from about 4.6 billion years ago to 541 million years ago. It encompasses about 90% of Earth's history and is divided into several eons, including the Hadean, Archean, and Proterozoic.
What era did autotrophic prokaryotes enrich the atmosphere with oxygen?
Autotrophic prokaryotes enriched the atmosphere with oxygen during the Archean and Proterozoic eras, starting about 2.5 billion years ago and continuing into the early stages of the Proterozoic era. This process, known as the Great Oxidation Event, was a significant turning point in Earth's history, leading to the rise of oxygenic photosynthesis and the oxygenation of the atmosphere.

How did the Proterozoic era end?
The Proterozoic era ended with the Cambrian Explosion, which took place around 541 million years ago. This event marked a rapid diversification of multicellular life forms, leading to the development of many complex organisms that laid the foundation for modern marine ecosystems.
What are the subdivisions of the Precambrian era?
The Precambrian era is divided into three subdivisions: the Hadean, Archean, and Proterozoic eons. These subdivisions represent different stages in Earth's early history, from the formation of the planet to the evolution of complex life forms.
