Question

What is the correct order of geological time scales from largest to smallest?

Answer 1

The correct order of geological time scales from largest to smallest is eon, era, period, epoch, age. Each division represents a different span of time and is based on significant events in Earth's history.

Step-by-step explanation:

The correct order of geological time scales from largest to smallest is as follows:

1. Eon
2. Era
3. Period
4. Epoch
5. Age

Each division represents a different span of time and is based on significant events in Earth's history. For example, an era is a subdivision of an eon, a period is a subdivision of an era, an epoch is a subdivision of a period, and an age is a subdivision of an epoch. These divisions help geologists organize Earth's history and understand the changes that have occurred over millions and billions of years.

Answer 2

This hierarchy comprises eons, eras, periods, epochs, and ages from the largest to the smallest

Step-by-step explanation:

This hierarchy comprises eons, eras, periods, epochs, and ages from the largest to the smallest. All of these are shown in the geological time scale page.

The Phanerozoic Eon reflects the period that most macroscopic species — bacteria, fungi, plants, and animals — lived through.
