Question

The geologic time scale is a system of chronological dating that relates
geological strata to time. In which portion of the Earth's history is embraced
by the geologic time scale?​

Answer 1

Answer: The geologic time scale was developed after scientists observed changes in the fossils going from oldest to youngest sedimentary rocks. ... Later, scientists used absolute dating to determine the actual number of years ago that events happened. The geologic time scale is divided into eons, eras, periods, and epochs.

Answer 2

The correct answer is The formation of earth which is depicted by geologic time scale.

This is because:

• The geologic time scale depicts a period of Earth's history based on the planet's rock strata.

• The geologic time scale categorises periods based on stratigraphy, which refers to the types of rocks existent at the time and how they transitioned to other types.
• It also displays events that occurred during the stone age, including which species appeared and vanished, as well as how species evolved till the present day.
• The fossils of species found in the rocks provided detailed information about the types of species that existed during the various stone ages.
• The geologic time scale began roughly 4 billion years ago and is still going strong today.
• It divides time into Eons, Eras, Periods, Epochs, and Ages, in descending order of duration.
