Eons. 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. As the Earth orbits the Sun, the Earth is pulled by the gravitational forces of the Sun, Moon, and large planets in the solar system, primarily Jupiter and Saturn. Over long periods of time, the gravitational pull of other members of our solar system slowly change Earth’s spin, tilt, and orbit. Over approximately 100,000 – 400,000 years, gravitational forces slowly …The Geologic Time Scale and a Brief History of Life on Earth The Geologic Time Scale is divided into four major units: Eons, Eras, Periods and Epochs. An Eon is the longest division of geologic time, so long in fact that there have only been four Eons. Collectively the first three eons are called the Precambrian, that stretch of

Relative time does not tell how old something is, all we know is the sequence of events. This book consolidates the latest research on the Hadean Eon - the first 500 million years of Earth history - which has permitted hypotheses of early Earth evolution to be tested, including geophysical models that include the possibility of plate tectonic-like behavior. These new observations challenge the longstanding Hadean paradigm – based ...
