    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
