Answer (1)
Upwelling is the process of deep, cold, and nutrient-rich water rising to the ocean surface, essential for marine ecosystems. This phenomenon takes place where winds push surface water away from the shore, allowing nutrient-rich waters to replace it. Areas like California and Peru are notable for their productive upwelling zones. ;
