Root Explanation

Gradiometer → It is formed from 'gradus' (meaning step or degree) and 'metron' (meaning measure). A gradiometer is an instrument that measures the gradient or change in a quantity, often used in fields like geophysics to measure variations in gravitational fields.

Memory Tip

Think of 'gradus' as steps or degrees, and 'metron' as measuring — a gradiometer measures the steps or changes in a certain quantity.
