Question
Explain how the land and sea breezes blow.
Solution
During day-time, land absorbs heat and becomes hotter than water in the sea. This is because the heat capacity of water is more than that of land.
The air in contact with land becomes hot and it moves up. This sets up a region of low pressure on land. As a result, the air above sea moves towards the land. This is called sea breeze.

During night, the earth and water in sea lose heat. The heat capacity of water is more than that of land. Therefore, there is a drop in the temperature in the land. Now, the air above water being warmer goes up and creates a region of low pressure above sea water. As a result air above the land moves towards the sea.
This is called the land breeze.
