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 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.
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.
The longest era lasting about 4 billion years was what era?
The longest era lasting about 4 billion years is the Precambrian era. It is divided into the Hadean, Archean, and Proterozoic eons and encompasses a vast span of time before complex life forms evolved.
What part of the earth was formed during the Precambrian Era?
The majority of Earth's continental crust, including many mountains and rocks, was formed during the Precambrian Era. This era lasted from about 4.6 billion to 541 million years ago.
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 ;)
When did the precambrian era begin?
The Precambrian Era began in the time period 4600 and ended in 570.
What are four divisions of geological time?
