Question

the process of upwelling brings which of the following to the surface? freshwater deoxygenated water warm water cold water

Explanation:

Upwelling is a process in which deep, cold, nutrient - rich water rises to the surface. It is not freshwater (oceanic upwelling is mainly in saltwater regions). Deoxygenated water is not typically what is brought up in a healthy upwelling (though in some cases with anoxic conditions it could be more complex, but generally not the main characteristic). Warm water is usually on the surface, and upwelling brings up cold water from the deeper layers.

Answer:

cold water
