Root Explanation

Microbarograph → It is formed from "micro-" (from Greek "mikros", meaning small) and "baro-" (from Greek "baros", meaning weight or pressure) and "-graph" (from Greek "grapho", meaning to write). The word refers to an instrument that writes or records small changes in atmospheric pressure.

Memory Tip

Think of 'small' ('micro-') changes in 'pressure' ('baro-') being 'written' ('-graph') down — that's what a microbarograph does.
