the life forms that lived in each era

the number of eras in Earth's history

Answer 1

The two correct answers you can determine by reading the geologic time scale are:

1. The events that ended major divisions of geologic time - The geologic time scale includes information about mass extinctions and other significant events that mark the boundaries between different geologic eras and periods.

2. The life forms that lived in each era - The geologic time scale provides details about the dominant life forms and significant biological developments that occurred during each era.

The other two options, "how old Earth is" and "the number of eras in Earth's history," are not directly determined from the geologic time scale alone. The age of Earth is known through radiometric dating, and while the geologic time scale outlines the divisions, the actual count may require specific interpretation.
