what is difference between conduction ,convection advection
Answers
Answer:
Generally convection is reserved for fluids.In fluids:Convection=Conduction + Advection , which means Convection is the total effect of conduction and advection. Its quite simple. Advection is the transport of energy (say heat) by movement of bulk fluid.
Answer:
Conduction:
The air in interaction with the land gets heated gradually and the upper layers in touch with the lower layers also get heated. This process is called conduction.
This process takes place when two bodies of uneven temperature are in contact with one another, there is a flow of energy from the warmer to the cooler body.
The heat transfer continues until both the bodies reach the same temperature or the contact is interrupted.
This process is significant in heating the lower layers of the atmosphere.
Convection:
The air in contact with the earth upsurges vertically on heating in the form of currents and transfers the heat of the atmosphere.
This vertical heating of the atmosphere is known as convection.
The convective transfer of energy is limited only to the troposphere.
Advection:
The transfer of heat through the horizontal movement of air is called advection.
The horizontal movement of the air is comparatively more significant than the vertical movement.
Most of the diurnal variation in weather is caused by advection only in the middle latitudes.
During summer in tropical regions predominantly in Northern India, local winds called ‘loo’ is the result of the advection process.
