Look at the map of ocean currents and answer the following:

How does the Humboldt current affect the climate of the South American coast?

Ocean currents are the horizontal continuous flow of a mass of water from one place to another. They are of 2 types – warm and cold ocean current. Ocean currents flowing along the coastline have an impact on its climate. Humboldt current is a cold ocean current flowing towards the north along the west coast of South America from the southern part of Chile to northern Peru. Thus, it brings cold water into warm water areas of northern Peru having a cooling influence in the climates of these regions. There is also dryness in the region due to cold current because cool marine air has low moisture holding capacity causing little or no precipitation.
