Which effect intensifies coastal erosion during an El Niño event on the western coast of South America?

💡 Explanation

When El Niño occurs, warmer ocean temperatures off the west coast of South America lead to increased evaporation and rainfall, which saturate coastal soils and raise sea levels contributing to destructive erosion processes. Therefore increased temperature and rainfall intensify erosion, rather than altered currents, wave events, or nutrients which have secondary effects.
