How old is the earth?
Earth is estimated to be 4.54 billion years old , plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date. In northwestern Canada, they discovered rocks about 4.03 billion years old.
What is today’s age called?
The Information Age , also called the Computer Age, the Digital Age and the New Media Age, is coupled tightly with the advent of personal computers, but many computer historians trace its beginnings to the work of the American mathematician Claude E.
What is the next era called?
Geological era
The next-larger division of geologic time is the eon .
What era are we in technology?
The Information Age (also known as the Computer Age, Digital Age, or New Media Age) is a historical period that began in the mid-20th century, characterized by a rapid epochal shift from the traditional industry established by the Industrial Revolution to an economy primarily based upon information technology.
What was the first era on Earth?
The first eon was the Hadean , starting with the formation of the Earth and lasting about 540 million years until the Archean eon, which is when the Earth had cooled enough for continents and the earliest known life to emerge.

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.
Which is the shortest era?
Quaternary Period
The Quaternary spans from 2.58 million years ago to present day, and is the shortest geological period in the Phanerozoic Eon. It features modern animals, and dramatic changes in the climate. It is divided into two epochs: the Pleistocene and the Holocene.
What is the last era?
The Cenozoic Era , meaning “new life”, is the current and most recent of the three Phanerozoic geological eras, following the Mesozoic Era and covering the period from 66 million years ago to the present. The Cenozoic is also known as the...
What will Earth be like in 1 billion years?
In about one billion years, the solar luminosity will be 10% higher than at present . This will cause the atmosphere to become a “moist greenhouse”, resulting in a runaway evaporation of the oceans. As a likely consequence, plate tectonics will come to an end, and with them the entire carbon cycle.
