Question

Sea breeze and land breeze
$\left(\text{A}\right)$ Are caused by currents set up in the air due to conduction
$\left(\text{B}\right)$ Are caused by currents set up in the air due to convection
$\left(\text{C}\right)$ Are caused by currents set up in the air due to radiation
$\left(\text{D}\right)$ Have no relation to conduction, convection, and radiation

Answer 1

Hint:
-The conduction generally takes place in solids.
-The conduction takes place in gas or liquid. If we keep some water in a pot and give heat then the upper portion of the liquid becomes hot by this convection process.
-The radiation process must need an inert medium to transmit heat from one place to another.

Complete step by step answer:
The land surface absorbs more heat from the sun than the sea surface. And in the day time the land becomes hotter than the water part due to the specific heat of water being greater than the land part. Hence, the air along the land surface rises, getting hot and light. To fill this blank space the cold air from the sea goes through the convection process of air to the land surface and this flow of air is called the Sea Breeze.

In the night time, the land surface becomes cool by emitting the heat very fast. Since the sea water radiates less heat than the land, it remains hotter than the land part. Hence the cold air from the land goes through the convection process of air to the seawater and this flow of air is called the Land Breeze.

The sea breeze and the land breeze is caused by the convection current of air.

The conduction or the radiation cant take place because The conduction generally takes place in solids and the radiation process must need an inert medium to transmit heat from one place to another.
Hence, the right answer is in option $\left(\text{B}\right)$.

Notes:
-The Sea Breeze flows in the day and by the evening it becomes more intense.
-The Land Breeze flows all over the night and becomes very fast in the dawn.
