1-5.
Which of the following
can affect atmospheric
conditions?
1.
Geographic height
factors
2.
Geographic location
3.
Changes in time
4.
All of the above
In what portion of the
atmosphere
does the majority
of weather phenomena take
place?
1.
Ionosphere
2.
Stratosphere
3.
Troposphere
4.
Hydrosphere
Because the stratosphere is a
relatively calm region with
little or no temperature
change,
it will have almost no
effect on radio wave
propagation.
1.
True

False
Variations in the ionosphere
resulting from changes in the
sun’s activity are known as
1.
regular variations
2.
irregular variations

In ionization, when an electron
is knocked free from a neutral
gas atom, what is the overall
charge of the atom?
1.
Negative

Neutral
4.
Inverted
1-7.
The frequency of ultraviolet
light passing through the
atmosphere has what
relationship to the ionospheric
layer it ionizes?
1.
It is inversely
proportional
2.
It is directly proportional
3.
It is inversely
proportional during the day
and directly proportional
at night
4.
It is directly proportional
during the day and
inversely proportional at
night
