Explain, with the help of a diagram, how convection plays a role in the formation of land breeze and sea breeze.

Answer»

Sea Breeze:

  • In the morning, due to HEATING effects of the sun, the land becomes hotter MUCH faster as COMPARED to the sea.

  • As a result, the air over the land becomes warmer as compared to the air over the sea.

  • Warm air (over land) being lighter moves upwards due to convection. Cool air from the sea moves in towards the land to fill the empty space.

  • This is called SEA BREEZE.

Land Breeze:

  • In the night, the land becomes cooler much faster as compared to the sea.

  • As a result, air over the sea still REMAINS more hot as compared to the air over the land.

  • Hot air (over sea) being lighter moves AFTERWARDS due to convection. Cool air from the land moves in towards the sea to fill the empty space.

  • This is called LAND BREEZE.

Hope It Helps.
