what is convection and advection?
Answers
Answer:
the process in which heat moves through a gas or a liquid as the hotter part rises and the cooler, heavier part sinks
the transfer of heat or matter by the flow of a fluid, especially horizontally in the atmosphere or the sea.

Explanation:
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 horizontal movement of air is called advection.
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 advection process.
