The Archean Eon was a period of time where the Earth was very hot and wet. The oceans were also very warm. Thousands of volcanic eruptions ejected volcanic ash that bombarded the earth and dust into the atmosphere causing violent lightning storms and continual rain. During this timeline the Earth atmosphere was polluted with enormous amount of Carbon and Sulfur dioxide concentration. Such levels of chemical content in the atmosphere would be very dreadful to the majority of living beings in the Earth today.

What is an eon?
In general speech, an eon can refer to a very long period of time. In science, an eon is the largest division in the geologic time scale. An eon is subdivided into two or more eras and lasts around a billion years or so. In Earth's history there are four eons in total: Hadean, Archean, Proterozoic, and Phanerozoic. We are currently in the Phanerozoic Eon.
What era was 3.5 billion years ago?
3.5 billion years ago was the Paleoarchean Era(3,600 - 3,200Ma). This was in the Archean Eon(3,800 - 2,500Ma) & during the Precambrian SuperEon(4,500 - 542Ma).

What is Archean Era?
The Archean era is the earliest Precambrian era, archean means "ancient" or "beginning". The Archean era starts with the oldest known rocks, about 4.6 billion years ago.
What eon is after the Hadean Eon?
archean eon
What plants lived in the Archean eon?
none
What happened at the end of the Archean Eon?
everything
What age is Archean?
the eon that constitutes the earlier (or middle) part of the Precambrian, in which there was no life on earth. It precedes the Proterozoic eon. Also called azoic .
How long did the Precambrain last?
Precambrian is an informal term for the time before the Cambrian Period, the first period of the Phanerozoic Eon. The Precambrian consists of three eons, the Hadean, the Archean, and the Proterozoic. The Hadean Eon is about 760,000,000 years long. The Archean Eon is about 1,300,000,000 years long. The Proterozoic Eon is about 1,960,000,000 years long This comes to a total of 4,025,000,000 years.
The largest division of geological time is called?
The Archean Eon, which is part of the Precambrian period along with the Proterozoic Eon.
The Archean Eon spans the time from the formation of the Earth until years ago?
2.5 billion years ago
During what era were the first one-celled organisms formed?
During the Archean Eon life started and was dominated by one-celled prokaryotic life forms. Eukaryotic one-celled organisms became dominant in the Proterozoic Eon. Multicellular organisms ruled the planet during the eon known as the Phanerozoic.
What was the era with no lifeforms on Earth?
The Hadean Eon, the earliest time interval, was when the Earth was cooling, and continents and oceans formed. Lifeforms are thought to have appeared in the following eon, the Archean Eon.(eras are a much smaller time interval, and the Hadean is not normally subdivided into these)
In science how long is an eon?
An eon is a made up of two or more eras. They are defined in terms of what was happening on the planet in biological and geological terms rather than in number of years. We are now 541 million yeras (Myr) into the current eon - the Phanerozoic eon. Before that was the Proterozoic eon which lasted 1959 Myr, the Archean eon (1500 Myr) and the oldest, the Hadean eon (500 Myr).
What period did the first prokaryotes appear?
In the Archean eon, precambrian era because the first prokaryote appeared around 3.5 billion years ago.
How long did the Proterozoic eon last?
The Proterozoic eon was the third eon in Earth history. It lasted from 2.5 billion years ago to 542 million years ago. Therefor, the Proterozoic was nearly 2 billion years long.Read more: How_long_did_the_proterozoic_era_last
