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).
how long does as eon last i needit 4 school asap thanks
An eon.
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.
Eon, era, period. Our Earth Science teacher told us to remember it as MEEP: majors eon era period. MEEP.
No unless you use an a.r code. The eon ticket was in an event a long time ago.
An example of eon in a sentence is ' Dinosaurs existed many eons ago on planet Earth.' The meaning of the word 'eon' is a long time ago.
An eon is the longest division of geologic time, representing billions of years. Eons are further divided into eras, periods, and epochs to categorize Earth's history in more detail. The current eon that we are in is the Phanerozoic eon, which began about 540 million years ago.

An eon is an indefinitely long period of time, in which there exist noteworthy periods known as eras.
The opposite meaning for eon is a short period of time which can be calculated or measured.Note: The answer is based on the assumption that the questioner asked the antonym for the word eon meaning immeasurably long period of time.
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.
