INSOLATION, CONDUCTION, CONVECTION,RADIATION,ADVECTION AND COMPRESSION

HEY FRIENDS

I am Aryan and your welcome in my blog..

So in this blog you will learn these point:

INSOLATION:

The incoming solar radiation, which reaches the surface of the Earth is called insolation. The amount of insolation reaching the surface of the Earth and its effectiveness per unit area depends upon the following factors:

The inclination of the Sun ray's
The amount of atmosphere to be crossed
The during of sunshine or the length of the day
The transparency of the atmosphere
The distance between the sun and the Earth
The Sunspot

Radiation:

Radiation is the transmission of energy in the form of electromagnetic waves.
The sun radiates heat energy in the form of short waves, whereas the radiation from the Earth is in the form the long waves.
The atmosphere behaves like a transparent medium for the short wave solar radiation
After receiving insolation, the surface of the Earth is heated and becomes a radiating body.

Conduction:

When two bodies having unequal temperature come in contact with one another, the heat energy flows from hotter body to the cooler body.This transfer of heat is called conduction.

Convection:

When the air is heated, it rises upwards. It leaves behind a partial vacuum near the surface of the Earth.
The continuous upward movement of the heated air mass pushes aside the air at the higher levels.
This is how the convection current develops above the surface of the Earth. This is process of heating the atmosphere is known as convection.
It helps in the transfer of heat of various layers of the atmosphere.

Advection:

Sometimes the air masses move from one region to another along with the winds.These winds carry the temperature of one place to another. The air temperature of a place thus rises or falls depending upon whether the wind is coming from a warm or a cool area.

Compression:

When the air current descends, it presses the lower layer of the atmosphere. Due to this pressure and the increasing weight of the upper layers,the lower layer of the atmosphere gets heated.
