The Precambrian Eon consists of three main eras: the Hadean, Archean, and Proterozoic eras.
Precambrian time is another name for the group of eons that includes the Hadean, Archean, and Proterozoic eons.
The two subdivisions of the Precambrian Era are the Hadean and the Archean Eons.
Precambrian time spans from about 4.6 billion years ago to around 541 million years ago. It represents roughly 90% of Earth's history and is divided into three eons: Hadean, Archean, and Proterozoic.
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.
The Precambrian era spans about 87 percent of Earth's history. It includes the Hadean, Archean, and Proterozoic eons and is characterized by the formation of Earth, the development of early life forms, and significant geological events.

The two subdivisions of the Precambrian Era are the Hadean and the Archean Eons.
There are four eons dividing the geologic scale. Three occurred during the Precambrian era.
These three eons form the Pre-Cambrian supereon.
The Hadean, Archean, and the protozoic eons.
The Precambrian time, which includes the majority of Earth's history, began approximately 4.6 billion years ago with the formation of the Earth. This time period encompasses about 88% of geologic time and is divided into the Hadean, Archean, and Proterozoic eons.

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.
Eons are the longest subdivision of geologic time. They are typically divided into eras, which are further divided into periods, epochs, and ages. Eons represent the largest time divisions in the geologic time scale.
• PRECAMBRIAN EON (noun)The noun PRECAMBRIAN EON has 1 sense:1. the eon following the Hadean time and preceding the Phanerozoic eon; from about 3,800 million years ago until 544 million years agoFamiliarity information: PRECAMBRIAN EON used as a noun is very rare.your lovely Chloe xxx
The Archean and Proterozoic eons make up the Precambrian era, which is the earliest and longest span of Earth's history, lasting from about 4.6 billion to 541 million years ago. These eons are characterized by the formation of Earth's continental crust, the development of life, and significant geological events that shaped the planet.
