The process of upwelling brings which of the following to the surface? freshwater, deoxygenated water, cold water, or warm water. *earth science*

 cold water

Explanation:

Upwelling is a oceanic phenomena. This involves the movement of the cold, dense and nutrient rich water to the oceanic surface. This water replaces the warm, and nutrient poor surface water. The process of upwelling promotes the growth of plants and phytoplanktons on the surface of oceanic water due to availability of nutrients that are necessary for growth.
