GEOLOGY

Detailed explanation-1: -Upwelling is the natural process which brings cold, nutrient-rich water to the surface. A huge upwelling regularly occurs off the coast of Peru, which enjoys a large fishing industry as a result. Upwelling is a process in which currents bring deep, cold water to the surface of the ocean.

Detailed explanation-2: -Upwelling is a process in which deep, cold water rises toward the surface. This graphic shows how displaced surface waters are replaced by cold, nutrient-rich water that “wells up” from below. Conditions are optimal for upwelling along the coast when winds blow along the shore.

Detailed explanation-3: -Upwelling occurs when winds push surface water away from the shore and deeper water rises to fill the gap. During upwelling, wind-displaced surface waters are replaced by cold, nutrient-rich water that wells up from below.

Detailed explanation-4: -Upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water from deep water towards the ocean surface. It replaces the warmer and usually nutrient-depleted surface water.

Detailed explanation-5: -Because of the Coriolis Effect, most of the water within about 150 to 300 feet of the surface (depending on the speed of the wind) is actually moving away from shore. This allows deep, cold water to flow toward shore and eventually rise up toward the surface.
