Correct Answer: Pressure gradient
Solution : The correct answer is Pressure gradient.
Differences in air pressure can cause air masses to travel from one point to another. Air masses tend to move from high-pressure locations to low-pressure locations. As a result, winds blow from high-pressure zones to low-pressure areas. Hence pressure conditions are one of the most important factors for blowing winds on Earth.
