Final answer:
Something being carried by westerlies moves toward the east.
Step-by-step explanation:
When something is being carried by westerlies, it is moving towards the east. Westerlies are prevailing winds that blow from west to east in the middle latitudes of both the Northern and Southern Hemisphere. These winds are responsible for many weather patterns and can carry objects or particles in an easterly direction. For example, if a balloon is released in an area where westerlies are present, it will be carried eastward by the wind.
