Final answer:
The effects of friction on the wind are strongest when the wind speed is high.
Step-by-step explanation:
The effects of friction on the wind are strongest when the wind speed is high. Friction is a force that opposes the motion of objects, so when the wind is moving fast, there is more contact between the air molecules and the surface it is flowing over. This increases the amount of friction and has a stronger effect on the wind's velocity and direction.
