Final answer:
The trade winds are affected by the Coriolis effect, causing winds in the Northern Hemisphere to be deflected to the right and winds in the Southern Hemisphere to be deflected to the left.
Step-by-step explanation:
The trade winds are affected by the Coriolis effect due to the rotation of the Earth. The Coriolis force causes winds in the Northern Hemisphere to be deflected to the right, while in the Southern Hemisphere, they are deflected to the left. This deflection leads to the formation of wind patterns such as the trade winds.
