Answer 1

The correct answer is Convection.

Key Points

Convection is the process of heat transfer by the bulk movement of molecules within fluid such as gases & liquids.
Type of convection:
- Natural convection
- Forced convection
Natural convection:
- When convection takes place due to buoyant force there is a difference in densities caused by the difference in temperature it is known as natural convection.
Forced Convection:
- An external source such as fans & pumps is used for creating induced convection, known as forced convection.
One of the common examples of natural convection is Land & sea breeze.
This phenomenon occurs during the day as land gets warmer quickly than the sea, the temp above the land rises and heats the surrounding air.
Warm air is less dense, it expands and starts rising to create a low-pressure area over the land meanwhile there is relatively high pressure over the sea.
The difference in pressure causes the air to flow from sea to land known as the Sea Breeze and Vice-versa in the night is known as Land breeze.

Additional Information

Acclimatization	It is the process in which an individual organism adjusts to a change in its environment, allowing it to maintain performance across a range of environmental conditions.
Radiation	It is the emission or transmission of energy that travels in the form of waves or particles through a material medium.
Conduction	Heat transfer through matter by molecular activity is known as conduction.
