  1. From experience we know that weather

    a)has no impact on our lives.
    b)does not change.
    c)varies only with time.
    d)varies from place to place and with time.
    Varies from place to place and with time

  2. A scientific model

    a)includes all the variables that operate in a system.
    b)is a precise representation of a real system.
    c)contains only the essential variables that operate in a system.
    d)is seldom used to make predictions.
    contains only the essential variables that operate in a system.

    A scientific model is an approximate representation or simulation of a real system. A model includes only what are considered to be the essential variables or characteristics of a system while omitting details considered non-essential.
  3. A scientific hypothesis

    a)is often an educated guess.
    b)may inspire few insights.
    c)is tested as part of the scientific method.
    d)All of the above are correct.
    is often an educated guess and is tested as part of the scientific method.

    State the educated guess in such a way that it can be tested, that is, formulate a hypothesis.
  4. Purdue University's Tornado Vortex Chamber is an example of a ________ model.

    a)numerical
    b)physical
    c)graphical
    d)conceptual
    physical

    A physical model is a small-scale (miniaturized) version of a system.
  5. Both ancient and modern volcanoes emit

    a)water vapor.
    b)carbon dioxide.
    c)nitrogen.
    d)All of the above are correct.
    All of the above are correct.
  6. Most atmospheric aerosols

    a)originate at Earth's surface.
    b)are products of photosynthesis.
    c)consist of meteorites.
    d)occur in the stratosphere.
    all of the above are correct

    Most aerosols occur in the lower atmosphere, near their sources on Earth's surface; they derive from wind erosion of soil, ocean spray, forest fires, volcanic eruptions, and industrial and agricultural activities. Also, some aerosols, such as meteoric dust, enter the atmosphere from above.
  7. The source of atmospheric nitrogen is

    a)decay of organic matter.
    b)ocean spray.
    c)photosynthesis.
    d)transpiration.
    decay of organic matter.
  8. All other factors being equal, higher concentrations of atmospheric CO2 will likely _______ the temperature of the lower troposphere.

    a)raise
    b)have no effect on
    c)lower
    raise

  9. Most water vapor occurs in the

    a)troposphere.
    b)stratosphere.
    c)mesosphere.
    d)thermosphere.
    troposphere
  10. The atmospheres of Mars and Venus are composed mostly of

    a)water vapor.
    b)ozone.
    c)nitrogen.
    d)carbon dioxide.
    carbon dioxide
  11. Normally within the troposphere, air temperature _____with increasing altitude.

    a)rises
    b)does not change
    c)falls
    falls
  12. The altitude of the tropopause is greater at the _____ than at the _____.

    a)equator....poles
    b)poles.......equator
    equator.....poles
  13. The transition zone between the stratosphere and mesosphere is known as the ________.

    a)thermopause
    b)stratopause
    c)mesopause
    d)tropopause
    stratopause
  14. Remote sensing of the atmosphere is by

    a)satellite.
    b)radar.
    c)radiosonde.
    d)all of the above
    radar and satellite
  15. A ________ is used to obtain sounding over the ocean.

    a)radiosonde
    b)rawindsonde
    c)dropwindsonde
    c)seasonde
    dropwindsonde

  16. Most clouds are confined to the

    a)troposhpere
    b)stratosphere
    c)mesosphere
    d)thermosphere
    troposphere
  17. A radiosonde monitors changes in _______with increasing altitude.

    a)temperature.
    b)air pressure.
    c)humidity.
    d)all of the above are correct.
    all of the above are correct
  18. The ionosphere is located primarily within the

    a)troposphere.
    b)stratosphere.
    c)mesosphere.
    d)thermosphere.
    thermosphere
  19. When the sun is active, solar flares become more intense and Earth's auroral ovals

    a)shrink.
    b)disappear.
    c)do not change.
    d)expand towards the equator.
    expand towards the equator

    Auroral acitivity varies directly with solar activity. When the sun is quiet, the auroral oval shrinks, but when the sun is active, the auroral oval expands toward the equator, and the aurora may be visible across southern Cananda and the northern United States or, rarely, further south.
  20. The greatest concentration of ions occurs in that portion of the atmosphere known as the

    a)troposphere.
    b)homosphere.
    c)stratosphere.
    d)ionosphere.
    ionosphere
