upwelling zones

Upwelling zones are areas in the ocean where deep, cold, nutrient-rich water rises to the surface. This process occurs due to winds pushing surface water away, allowing the heavier, nutrient-laden water to take its place. These zones are vital for marine life, as they support high productivity and populations of fish and other sea creatures. Commonly found along coastlines, such as the Pacific coast of the Americas, upwelling regions contribute significantly to global fisheries, making them crucial for both ecological balance and human food supply.
