1. In January, off the west coast of California there is a
a. low pressure cell.
b. high pressure cell.
c. pirate ship.
d. no pressure cell.
2.
Which of the following best describes relative humidity?
Select one:
a. water vapor content divided by saturation mixing ratio times 100
b. water vapor content times saturation mixing ratio times 100
c. humidity divided by saturation mixing ratio times 100
d. saturation mixing ratio divided by water vapor content times 100
3.
Air is saturated when it contains all the water vapor that it can hold at a particular temperature. The temperature at which saturation occurs is called the
Select one:
a. saturation point.
b. maximum vapor capacity.
c. humidity.
d. dew-point temperature.
4,
When a solid turns into a liquid, or ice to water, we call this melting. What do we call solid turning into gas, or ice turning into vapor?
Select one:
a. deposition
b. sublimation
c. condensation
d. evaporation
Explanation / Answer
(1) In January, off the west coast of California there is a low pressure cell
Thus, the correct option is (a)
----------------------------------------------------------------------------------------------------------------------------
(2) Relative humidity is the ratio of actual pressure to saturation vapour presure.
That means relative humidity is water vapor content divided by saturation mixing ratio times 100
Thus, the correct option is (a)
-----------------------------------------------------------------------------------------------------------------------------
(3)
Air is saturated when it contains all the water vapor that it can hold at a particular temperature. The temperature at which saturation occurs is called the dew point temperature.
Thus, the correct option is (d)
----------------------------------------------------------------------------------------------------------------------------------------------
(4) The process solid turning into gas, or ice turning into vapor called sublimation.
Thus, the correct option is (b)
