Q.

1. The transfer of heat through vertical movement of air is called advection.
2. Horizontal movement of the air is relatively more important than the vertical movement for the heating and cooling of the atmosphere.
3. Seasonal local wind ‘Loo’ is the outcome of the advection process.

2. 2 and 3 only
3. 3
4. 1

Q. What is conduction?

1. The mechanism of transfer of heat between two adjacent parts of a body because of same temperature.
2. The mechanism of transfer of heat between two adjacent parts of a body because of difference in humidity.
3. The mechanism of transfer of heat between two adjacent parts of a body because of their temperature difference.
4. The mechanism of transfer of energy between two adjacent parts of a body because of their difference in state.

1. Longwave
2. Shortwave
3. Terrestrial wave
4. Electromagnetic
