18. Wind speed on Earth is reduced by which?

A. temperature

B. friction

C. weather

D. convergence

your answer would be A. temperature

Explanation:

Wind speed on Earth is reduced by temperature, it depends on the temperature because let's say there is a nice sunny day, then obviously it will reduce the wind speed

Temperature reduces the wind speed on earth.

Explanation:

Wind speed is an atmospheric quantity that causes the wind to flow from high to low level due to a change in temperature. Wind speed is controlled by the pressure gradient factor and it increases the wind speed with increase in pressure gradient. Wind speed decreases with an increase in temperature value as it absorbs the heat developed in the system and wind gets slowed down. Wind speed is measured in velocity and anemometer is used to measure the rate of wind speed.
