The geologic time scale that represents the longest time span is the eon. It is a unit of time that is equal to a billion years.
The oldest division of geologic time is the Precambrian, specifically the Archaean Eon from which the oldest rocks and fossils date. (The Hadean Eon preceded the Archaean, but no geologic records date from this time because the Earth was cooling from a molten state.)
The period of Earth's time that would be considered longest is the Precambrian Era.
The Proterozoic Eon, which lasted from about 2.5 billion to 541 million years ago, was the longest geologic time era. It was a time of significant biological and geological evolution, including the emergence of early multicellular life forms.
Which of the following forces would take the longest amount of time to change the surface of the Earth
The geological time scale, divided into eons, eras, periods, epochs, and ages, is organized based on key events in Earth's history, such as mass extinctions and the appearance of significant life forms. Each division represents a period when particular types of plants and animals dominated the planet, leading to the classification of geological time periods based on the fossil record and evolutionary history of life on Earth.
Eons
Supereon is the longest classification of time in geology. The Precambrian period is a supereon comprised of the Hadean, Archean, and Proterazoic eons.
Cenozoic Mesozoic Paleozoic Precambrian
the longest division of geological time; an immeasurably long period of time; a divine power or nature emanating from the Supreme Being and playing various roles in the operation of the universe. Hope it can help you.
The oldest division of geologic time is the Precambrian, specifically the Archaean Eon from which the oldest rocks and fossils date. (The Hadean Eon preceded the Archaean, but no geologic records date from this time because the Earth was cooling from a molten state.)
Eon
The Precambrian is actually the longest block (division) of time in earth geological history. But the Paleozoic era is the longest of the three "eras". The paleozoic era started about 550 million years ago and is marked by the appearance of abundant invertebrate life in the oceans. The paleozoic era ended about 225 million years ago with the forming of the supercontinent Pangaea.
The longest in geological time is an Eon eg. Archeozoic Eon . Edit: there is also the supereon, which is usually composed of 2-3 eons.
The longest division of geologic time, containing two or more eras.Answer:Although usually taken to mean just a very long time, astronomy and geology use eon to mean a billion years.
The Precambrian.
The Archean Eon, which is part of the Precambrian period along with the Proterozoic Eon.
Geological time spans are broken down in different ways depending on the system used. See the link below.
