Have you ever heard of a diatreme?

I think so, isn't it a volcanic feature?

Yeah, it forms when gas-filled magma explodes through the surface.

Root Explanation

Diatreme is formed from "dia-" (meaning through) and "treme" (from the Greek "trēma", meaning hole or perforation). The word refers to a volcanic feature characterized by a hole or opening that extends through layers of rock.

Memory Tip

Think of something that goes 'through' ('dia-') a 'hole' ('trēma') — that's why diatreme refers to a volcanic opening.
