Root Explanation

Diapir is derived from the Greek word "diapeirein" (meaning to pierce through) which combines "dia-" (meaning through) and "peirein" (meaning to pierce). A diapir refers to a geological formation where material rises through the surrounding rock, effectively piercing through it.

Memory Tip

Imagine material 'piercing through' ('dia-') the earth's crust, which helps you remember that a diapir is a geological feature that rises through surrounding rock.
