Upwelling
The vertical movement of cold water from the deep ocean to the surface
Real World Example
Imagine trying to find your favorite sweater that's buried at the bottom of a messy, overstuffed drawer. Just like how you dig through layers of clothes to bring that sweater to the top, upwelling involves the movement of cold, nutrient-rich water from the depths of the ocean to the surface. In this analogy, the sweater represents the cold, nutrient-rich water, the layers of clothes are like the warmer surface waters, and your action of pulling the sweater up mirrors the upwelling process.
