Geologic time scale - Wikipedia

The geologic time scale is a way of representing deep time based on events that have occurred throughout Earth's history, a time span of about 4.54 ± 0.05 Ga (4.54 billion years). It chronologically organises strata, and subsequently time, by observing fundamental changes in stratigraphy that correspond to major geological or paleontological ...

June 13, 2019 at 5:30 am. Imagine the nearly unimaginable: 4.6 billion years. That?s how old the Earth is ? a mind-boggling length of time. And to measure it, scientists use special terms, most of which focus on the planet?s changing geology. That?s why, in fact, it?s known as geologic time.

Scientists have put together the geologic time scale to describe the order and duration of major events on Earth for the last 4 1 ? 2 billion years. Some examples of events listed on the geologic time scale include the first appearance of plant life on Earth, the first appearance of animals on Earth, the formation of Earth?s mountains, and ...
