Question

Explain with a diagram how sea and land breezes are set up

Answer 1

In the day, when the sun is up, the land heats up very quickly and the air above it warms up a lot more than the air over the water. The warm air over the land is less dense and begins to rise. Low pressure is created. 

The air pressure over the water is higher with cold dense air, which moves to occupy the space created over the land. The cool air that comes along is called a sea breeze.

In the night, the reverse happens. The land quickly loses its’ heat whiles the water retains its’ warmth. This means the air over the water is warmer, less dense and begins to rise. Low pressure is created over the water. Cold and dense air over the land begins to move to the water surface to replace the warmer rising air. The cool breeze from the land is called a land breeze.

Answer 2

Explanation:

during the day the air over the land become water and lighter and Rises up the air from the Sea which is cooler and heavier rushes to take the place created by hot rising air. therefore a sea breeze blows during the day

during the night land loses heat faster than water and become cooler the air over the sea is now warm it rise up the cooler air over the land rushes to take its place. thus observe a land breeze at night
