The cold arrows in the image are correct. Because warm air rises and land breeze is air that travels towards the sea, only the cold arrow is right.
What is heat transfer?
The term “heat transfer” refers to the movement of heat. The flow of heat across a system's boundary is due to a temperature differential between the system and its surroundings.
The flow of hot and cold air is critical for transporting heat and energy throughout our globe. The density of hot air is lower than that of cold air.
Dense means that hot air is lighter and cold air is heavier. As a result, heated air rises while cold air falls.
Because warm air rises and land breeze is air that travels towards the sea, only the cold arrow is right.
Hence, the cold arrows in the image are correct.
