During the sea breeze:
During the sea breeze: Correct Answer Pressure is lower but temperature is higher over the land compared to the sea
CONCEPT:
Methods of Heat Transfer:
Conduction:
- The heat transfer through direct physical contact is known as conduction.
- Heat transferred from the electric burner of a stove to the bottom of a pan is transferred by conduction.
- This method of heat transfer is applicable in
Radiation:
- When electromagnetic radiation is emitted or absorbed to transfer the heat or When heat is transferred in the form of electromagnetic waves is known as radiation.
- Electromagnetic radiation includes microwaves, radio waves, infrared radiation, visible light, ultraviolet radiation, gamma rays, and X-rays.
- The method does not require any medium so heat from the sun reaches us by this method.
Convection
- It is heat transfer by the movement of its molecules.
- It occurs only in fluids (liquid and gas) not in solids because solid particles can not move from one place to another.
- For example, in a pot boiling water on the stove, or in thunderstorms, where hot air rises up to the base of the clouds.
- The sea breeze and land breeze occur due to convection.

-
This process takes place for the duration of the day. Both the sea and the land surface are heated up by the sun.
-
The sea heats up slower than the land because it has a much higher heat capacity.
-
Thus, the temperature over the land surface increases, in turn, heating up the surrounding air.
-
Expansion occurs in the less dense warm air and an area over the land having low pressure is developed. At the same time on the top of the sea, a high-pressure area develops.
-
Due to the difference in pressure and the air flows from the high pressure over the sea to the low pressure over the land.
-
Hence, option 3 is correct.
