Precambrian
The Precambrian Eon represents about 88 percent of geologic time on Earth. This eon includes all time prior to the Paleozoic Era and spans from the formation of the Earth about 4.6 billion years ago to the beginning of the Paleozoic Era around 541 million years ago.
The geologic time scale spans approximately 4.6 billion years, encompassing the history of Earth from its formation to the present day. It is divided into eons, eras, periods, epochs, and ages to categorize and understand Earth's geological history.
The geologic time scale spans millions to billions of years and is used to categorize Earth's history based on geological events. Time scales for human activities or accomplishments are much shorter and focus on events within human history, typically ranging from centuries to millennia. Additionally, human time scales are often culturally or socially defined, highlighting specific milestones or developments in human civilization.
The largest era in Earth's history is the Precambrian, which spans from the formation of Earth around 4.6 billion years ago to the beginning of the Phanerozoic eon around 541 million years ago. The Precambrian makes up about 88% of Earth's history.
The Precambrian era makes up about 90 percent of Earth's history. It spans from the formation of Earth around 4.6 billion years ago to the beginning of the Phanerozoic eon around 541 million years ago. It is characterized by the development of the Earth's atmosphere, oceans, and the emergence of life.
The division of geologic time that makes up about 88 percent of Earth's history is called the Precambrian eon. It spans from the formation of Earth around 4.6 billion years ago to the beginning of the Phanerozoic eon around 541 million years ago.
The Proterozoic Eon spans the largest percentage of Earth's history, accounting for about 42% of Earth's history. It lasted from around 2.5 billion years ago to 541 million years ago.

The Precambrian Eon represents about 88 percent of geologic time on Earth. This eon includes all time prior to the Paleozoic Era and spans from the formation of the Earth about 4.6 billion years ago to the beginning of the Paleozoic Era around 541 million years ago.
The geologic time scale spans approximately 4.6 billion years, encompassing the history of Earth from its formation to the present day. It is divided into eons, eras, periods, epochs, and ages to categorize and understand Earth's geological history.
The geologic time scale covers the entire history of Earth, which spans approximately 4.6 billion years. It is divided into eons, eras, periods, epochs, and ages to categorize and study Earth's history.
The existence of people on Earth is relatively short compared to the length of geologic time on Earth. Humans have been around for only a tiny fraction of Earth's history, which spans billions of years. Geologic time encompasses vast scales of time, with the history of humanity representing just a minuscule portion of it.
The Earth's geologic time scale spans about 4.6 billion years, from the formation of the Earth to the present day.
