How long is a era?
An era in geology is a time of several hundred million years. It describes a long series of rock strata which geologists decide should be given a name. An example is the Mesozoic era, when dinosaurs lived on the Earth. An era is made up of periods, and several eras make up an eon.
What was the first era called?
HadeanThe primary and largest catalogued divisions of time are periods called eons. The first eon was the Hadean, when the Earth and moon were predicted to be formed, lasting over 600 million years until the Archean, which is when the Earth had cooled enough for continents and the earliest known life to emerge.
