Question

why is the process of upwelling along the coast of south america important, and how does el niño disrupt it? upwelling brings cold, nutrient - rich water to the surface, supporting marine life; during el niño, warm water covers the area, stopping upwelling. upwelling brings warm water to the surface; during el niño, cold water flows in, increasing the amount of nutrients in the water. upwelling creates ocean currents, but el niño reverses those currents, causing flooding. upwelling allows deep - sea volcanoes to release heat; during el niño, the process stops, trapping heat in the atmosphere.

Explanation:

Upwelling along the South - American coast brings cold, nutrient - rich water to the surface which supports marine life. During El Niño, warm water covers the area, stopping upwelling. This is because El Niño causes warm water to flow to the surface, increasing the amount of warm water and reducing the upwelling of cold, nutrient - rich water.

Answer:

Upwelling brings cold, nutrient - rich water to the surface, supporting marine life; during El Niño, warm water covers the area, stopping upwelling.
