4. Wind moves because air above land is cooler than air above water
Explanation:
The land breeze is the movement of air from the land toward the sea. This air movement occurs during the night, when the land is quickly cooling off. As the land cools off, the air above it cools off quickly too. The air over the sea though cools off much slower and much less. The cooler air is denser than the air that is warmer, so it pushes the warmer air away, or rather the air from the land is moving toward the sea as a cool land breeze.
4. Wind moves because air above land is cooler than air above water.
Explanation:
Land breeze is a natural phenomenon that occurs in the night. This phenomenon occurs when the surface of the earth cools faster than the surface of the water causing the wind to move because the air above the earth is colder than the air above the water. This is because the thermal conductivity of water is less than that of earth. For this reason, during the day the water will be responsible for providing latent heat to the terrestrial surface and will be hotter than the earth at night.
