Earth Systems & Cycles Vocabulary

If differences in air pressure produce winds, what can you conclude about temperature and air pressure based on the figure?

• As warm air rises, it creates an area of lower pressure, and cooler air flows in as wind
• Warm air is denser than cold air is, creating an area of high pressure the produces wind.
• Winds flow from areas of low pressure to areas high pressure when temperature is warmer
• Air pressure decreases at night because temperature is lower, producing land and sea breezes
