The trade winds are like a superhighway for air, circling the Earth between 30° north and south of the equator. They blow constantly from east to west, thanks to the Sun heating the air near the equator and the Earth's rotation giving it a slight tug. Imagine a giant conveyor belt of air, always moving west.

Some explanations:

Direction: East to west, slightly north or south, depending on the hemisphere.

Reason: The Sun heats the air near the equator, causing it to rise and create low pressure. Cold air comes in from the edges after being deflected by the rotation of the Earth. Speed: Typically 5-13 mph, but can be faster. Effects: Brings rain to the western coasts of continents, helps in quick sailing and influences global climate patterns.

That is why it was named trade wind because fast sailing helped in trade.
