7.2 Ionospheric Regions
Practice
B-007-02-01
What causes the ionosphere to form?
Lightning ionizing the outer atmosphere
Solar radiation ionizing the outer atmosphere
Release of fluorocarbons into the atmosphere
Temperature changes ionizing the outer atmosphere
B-007-02-02
What type of solar radiation is most responsible for ionization in the outer atmosphere?
Microwave
Ionized particle
Ultraviolet
Thermal
B-007-02-03
Which ionospheric region is closest to the earth?
The E region
The D region
The F region
The A region
B-007-02-04
Which region of the ionosphere is the least useful for long distance radio-wave propagation?
The F2 region
The F1 region
The D region
The E region
B-007-02-05
What two sub-regions of ionosphere exist only in the daytime?
Troposphere and stratosphere
Electrostatic and electromagnetic
D and E
F1 and F2
B-007-02-06
When is the ionosphere most ionized?
Dawn
Midnight
Midday
Dusk
B-007-02-07
When is the ionosphere least ionized?
Shortly before dawn
Just after noon
Just after dusk
Shortly before midnight
B-007-02-08
Why is the F2 region mainly responsible for the longest distance radio-wave propagation?
Because it exists only at night
Because it is the lowest ionospheric region
Because it does not absorb radio waves as much as other ionospheric regions
Because it is the highest ionospheric region
B-007-02-09
What is the main reason the 160, 80 and 40 metre amateur bands tend to be useful only for short-distance communications during daylight hours?
Because of auroral propagation
Because of D-region absorption
Because of magnetic flux
Because of a lack of activity
B-007-02-10
During the day, one of the ionospheric layers splits into two parts called:
D1 & D2
E1 & E2
A & B
F1 & F2
B-007-02-11
The position of the E layer in the ionosphere is:
below the D layer
below the F layer
sporadic
above the F layer
