Upwelling

The vertical movement of cold water from the deep ocean to the surface
Real World Example
Imagine being in a crowded room where the air feels stuffy, and opening a window allows fresh, cooler air to circulate and refresh the space. This is similar to the ocean's process of upwelling, where cold, nutrient-rich water from the deep ocean rises to the surface, rejuvenating the marine environment. Just like how opening a window brings in fresh air to replace the stale, warmer air, upwelling brings essential nutrients from the ocean depths, invigorating marine life and promoting biodiversity at the surface.
