Temperature increases with height due to gamma rays, X-rays, and UV radiation.
Molecules are converted into ions, which results in the Aurora Borealis
(Northern Lights) in the Northern Hemisphere and the Aurora Australis
(Southern Lights) in the Southern Hemisphere. The Aurora Borealis most often
occurs from September to October and from March to April.


WEATHER AND CLIMATE

Weather is caused by the movement or transfer of heat energy, which results
from the unequal heating of Earth’s surface by the sun, and influences the
following physical properties: temperature, air pressure, humidity, precipitation,
available sunshine determined by cloud cover, wind speed, and wind direction.
Climate describes the total of all weather occurring over a period of years in a
given place. Energy can be transferred wherever there is a temperature difference
between two objects. Energy can be transferred through radiation, conduction,
and convection.
Radiation is the flow of electromagnetic radiation. It is the method by which
Earth receives solar energy.


Weather  describes   whatever    is currently    happening   outdoors.   Climate
describes weather patterns in a place over a period of years.
