Did you know that some rocks can be classified as metamorphic?

Really? I always thought they were just regular rocks.

Yeah, they change due to heat and pressure over time.

That's fascinating! I need to learn more about geology.

Root Explanation

Metamorphic → It is formed from "meta-" (meaning change) and "morphē" (meaning form or shape). The word describes a change in form or structure, particularly in geology where rocks undergo transformation.

Memory Tip

Think of 'change' ('meta-') in 'form' ('morphē') — that's why metamorphic refers to rocks that have changed their form.
