Put these time divisions in order, from longest to shortest.swap_vertEraswap_vertEonswap_vertEpochSUBMITarrow_backPREVIOUS

To order the time divisions from longest to shortest, we will examine the definitions of each term:

1. Eras: A significant period in history marked by distinctive characteristics, it typically encompasses multiple eons.
2. Eons: The largest division of geological time, consisting of multiple eras. Eons can span billions of years.
3. Epochs: These are divisions of time within an era and can last several million years but are shorter than eras.

Conclusion

Arranging these divisions from longest to shortest results in:

1. Eons
2. Eras
3. Epochs

Thus, the correct order is Eons → Eras → Epochs.
