Where was precambrian era?
The Precambrian era was a geological period that spanned from about 4.6 billion years ago to around 541 million years ago. It encompasses the earliest part of Earth's history, including the formation of the planet and the evolution of life forms. The Precambrian era was followed by the Paleozoic era, which marked the beginning of complex life on Earth.
What is the time range of Precambrian Era?
Precambrian time - The period in the geologic time scale from the formation of the Earth to the beginning of the Palezonoic era, from about 4.6 billion to 543 million years ago.
What part of the earth was formed during the Precambrian Era?
50% of Canada was created during this era. This part is called Canadian Shield.
Why is the PreCambrian era not divided into periods?
The Precambrian era is not divided into periods because the geological record from this time is more limited and less well understood compared to more recent eras. The lack of distinct fossils and rock layers make it challenging to establish clear boundaries for periods within the Precambrian. Instead, geologists have divided it into eons - the Hadean, Archean, and Proterozoic eons.
Early organisms in the Precambrian era converted what to oxygen?
Early organisms in the Precambrian era converted carbon dioxide to oxygen through photosynthesis. This process eventually led to the increase in atmospheric oxygen levels, paving the way for the evolution of more complex life forms.
What are two subdivisions of the Precambrian Era called?
The two subdivisions of the Precambrian Era are the Hadean and the Archean Eons.

Which describes the correct order of the geologic time scale from oldest to most recent?
ok im going to start off by saying this, the last answerer is stupid, and doesnt know what he is talking about. it goes from: PERIOD ERA EPOCH there you go ;)
