Root Explanation

Upwelling is formed from "up" (meaning in a higher position or direction) and "welling" (from Old English "wellan", meaning to spring or flow). The word describes the process of water rising from the depths to the surface, often bringing nutrients with it.

Memory Tip

Think of water 'springing up' from below — 'up' indicates direction, and 'welling' means to flow. This helps you remember that upwelling refers to water rising to the surface.
