Question

passage 5001 directions: the diagram below shows how el niño occurs when pacific trade winds that are blowing east to west weaken. use the diagram and your knowledge of science to answer any questions that follow. the weaker trade winds cause a water off the coast of north america to become cooler b water off the coast of australia to become warmer c water off the coast of indonesia to become cooler d water off the coast of south america to become warmer

Explanation:

During El - Niño, the weakening of trade winds allows warm surface water to flow eastward. This causes the water off the coast of South America to become warmer as warm sea currents replace the cold water. In normal years, cold water upwells off the coast of South America due to the west - blowing trade winds. When these winds weaken in El - Niño years, this upwelling is disrupted and warm water moves in.

Answer:

D. water off the coast of South America to become warmer
