  • Q1

    Ozone id one of the components of the Earth's atmosphere. Which is the following is TRUE about ozone in our atmosphere?

    Ozone is the same as oxygen we breathe

    Ozone is formed when an electric discharge is passed through molecular oxygen

    Ozone is created when a molecule of oxygen (O2) and another molecule of oxygen (O2) collide in the presence of a third, neutral molecule.

    Ozone is evenly distributed in our atmosphere

  • Q9

    For condensation to occur, air must be saturated. Saturation of air takes place when either of the following happens EXCEPT ___.

    there is downward movement of air

    there is a surface on which water vapor can condense

    when air is cooled to its dew point

    when water vapor is added to air

  • Q10

    Relative humidity depends on two factors: temperature and amount of moisture added to or removed from air. Which does NOT happen if temperature is changed? 

    When temperature is lowered relative humidity remains the same.

    When air is cooled beyond dew point more moisture is held, thus increasing relative humidity

    Cooling of air beyond dew point produces precipitation in the form of clouds, dew, or fog

    When temperature is increased, relative humidity is increased
