Did you know that some rocks are considered azoic?

Really? What does that even mean?

It means they’re from times before any life existed, just barren land.

That’s interesting! I never thought about how old some rocks could be.

Root Explanation

Azoic is formed from "a-" (meaning without) and "zoic" (from Greek "zoikos", meaning relating to animals or life). The word describes a condition or period that is without life or animals.

Memory Tip

Think of 'a-' meaning without and 'zoic' relating to life or animals — this helps you remember that azoic refers to a time or state without life.
