Answer:
The blue arrows in circles indicate that cool air is sinking
Explanation:
Warm air is less dense than cool air. For this reason, warm air rises, creating a low pressure region, and cool air, which is more dense than warm air, sinks creating a high pressure zone. In this description, the red arrows represent the hot air rising up to the sky, and the blue arrows represent the cool air sinking down. The reason warm air is less dense is because its molecules are further apart than when it is cold, making it lighter per cubed square foot.
So, we can conclude that option a) Warm air is rising is incorrect, because the warm air rising is represented by the red arrows pointing up form the land to the sky.
Options c) Cool air is less dense and d) warm air is more dense are also incorrect, because as mentioned before, cool air is more dense than warm air.
