Question

How does heat travel in air? Explain the sea breeze and land breeze in coastal areas in this reference.

Answer 1

Heat travels in air through the process of convection. The air near the heat source gets hot and rises up. The cool air from the sides comes in to take its place. In this way the air gets heated up.
In the coastal areas, people experience an interesting phenomenon. The land gets heated faster than the water during the day. The air over the land becomes hotter and rises up. The cooler air from the sea rushes in towards the land to take its place. The warm air from the land moves towards the sea to complete the cycle.
The flow of cool air from the sea towards the land to replace the hot air on land, is called sea breeze. At night it is just the reverse: The water cools down more slowly than land. So the cool air from land moves towards the sea. This is called land breeze.
