Question

Which of these facts could you determine by reading the geologic time scale? Select the two correct answers.

Answer 1

I don’t see the answer choices — could you paste them? Without them I can’t pick two.

To help, here are the kinds of facts you can and can’t determine from a geologic time scale:

- You can determine (examples)
- the names and relative order of time units (eons, eras, periods, epochs)
- the approximate absolute ages (in millions of years) or ages of the boundaries (e.g., when the Cretaceous ended ~66 Ma)
- the durations of intervals (how long a period or era lasted)
- the timing of major events marked on the scale (e.g., major mass extinctions)

- You cannot determine (examples)
- details about specific species’ behaviors, anatomy, or ancestry
- local rock types, exact fossil occurrences at a specific site, or counts of species
- fine-scale climatic details or exact dates of individual volcanic eruptions (beyond what’s summarized as major events)

If you paste the four (or more) choices, I’ll pick the two correct ones.
