Through conduction the atmosphere is heated up from the earth. The radiant energy that
is stored in the earth conducts to a mass of air and warms the gas molecules up.They expand
and move faster.
Radiation also plays a big part in heating the atmosphere. Radiant energy from the sun travels
through space in waves to heat the gas molecules in the atmosphere.
The mass of air that got its heat through conduction, rises, and then reradiates the heat to
other masses of air up in the atmosphere. These molecules also expand and move faster creating
a warmer atmosphere.
