Final answer:
Temperature, wind speed, and air pressure are the primary factors that influence circulation.
Step-by-step explanation:
The primary factors that influence circulation are temperature, wind speed, and air pressure.
Temperature affects circulation because it determines the density of air. When the air is warm, it expands and becomes less dense, causing it to rise. This creates an area of low pressure, which leads to the movement of air.
Wind speed is another important factor that influences circulation. When wind blows, it creates areas of high and low pressure. Air moves from areas of high pressure to areas of low pressure, resulting in circulation.
Lastly, air pressure plays a crucial role in circulation. Changes in air pressure cause the movement of air and influence wind patterns.
