Final answer:
Ocean currents, such as El Niño, have a significant impact on climate and weather patterns.
Step-by-step explanation:
Ocean currents have a significant impact on climate and weather. An example of this is the warm ocean current off the west coast of South America known as El Niño. This current disrupts normal weather patterns around the world and can cause extreme weather events in certain regions. For example, during an El Niño event, the Pacific Northwest in the United States may experience warmer and drier winters, while parts of South America may experience heavy rainfall and flooding. These changes in weather patterns are a direct result of the influence of surface currents on climate.
