Final answer:
Trade winds are consistent winds that blow from the east towards the west, hence they are easterly in direction. They are particularly notable for their role in historical sea voyages.
Step-by-step explanation:
Trade winds are characterized by their consistent direction and are part of the global wind system that dominates the Earth's equatorial region. These winds originate from the subtropical high-pressure areas and blow towards the equator. They are named for their ability to quickly propel trading ships across the ocean. Trade winds are easterly in direction. This means that they generally blow from the east towards the west. The consistency and reliability of these winds were crucial for historical sea voyages and trade routes, which is how they received their name.
