प्रश्न
Explain the direction of air movement during the day and night in coastal areas.
उत्तर
Direction of air during day and night in coastal areas:
During daytime, the cool air flows from the sea towards the land, because at this time, the land gets heated faster than the water. It generates a low-pressure area above the land as compared to air over the sea. Hence, the air from high-pressure area moves towards the low-pressure area.
During night, cool air from the land flows back to the sea because the land gets cooled down rapidly at night and the pressure of air above the land becomes higher then the air above the sea. Hence, there is a reverse flow of air.
