Eon time length.

Geologic eon. A geologic eon is the largest unit of time for the geologic time scale (Figure 1). Geologic eons are also referred to as "eonothems" (the chronostratigraphic name) or simply "eons". Eons are hundreds, even thousands, of years in length. Eons are made up with shorter eras. [1] Currently the eons are: [1] Phanerozoic (the current eon) In geochronology, time is generally measured in mya (million years ago), each unit representing the period of approximately 1,000,000 years in the past. The history of Earth is divided into four great eons, starting 4,540 mya with the formation of the planet. Each eon saw the most significant changes in Earth's composition, climate and life.The term Phanerozoic derives from the Ancient Greek words φανερός ( phanerós ), meaning visible, and ζωή ( zōḗ ), meaning life; since it was once believed that life began in the Cambrian, the first period of this eon. The term "Phanerozoic" was coined in 1930 by the American geologist George Halcott Chadwick (1876–1953). Are the other names for lengths of time like year, decade, century, etc? Second, Minute, Hour, Day, Week, Month, Year, Decade, Century, and Millennium, and I know an Eon is around a billion years; but are there others for lengths like 10k, 100k, 1mil, 10mil, etc?

Sep 25, 2023 · Archean Eon, interval lasting from about 4.0 billion to 2.5 billion years ago, the first formal division of Precambrian time.

There are 24 hours in a day and 365.25 days in a year. This means that there are 86,400 seconds in a day and 31,536,000 seconds in a year. An eon would then be in the trillions of seconds. It would take almost 32 million years to count to one trillion! So an eon is a very long time indeed. Even in seconds.Is An Era Longer Than A Eon?
