What is the main role of the westerlies? question 6 options: forcing the cold air toward the poles provide ships with clear sailing around the equator carrying the warm, equatorial waters and winds to the western coasts of continents distributing even temperatures across continents save

The right option is; carrying the warm, equatorial waters and winds to the western coasts of continents  

The westerlies are the prevailing winds that blow at two regions on earth. The westerlies blow between 30 and 60 degrees latitude in both the northern and southern hemisphere. The wind usually comes from high-pressure regions in the horse latitudes and moves towards the poles. The westerlies perform a vital role in carrying the warm, equatorial waters and winds to the western coasts of continents, particularly in the southern hemisphere due to its broad oceanic region.
