Worksheets8 - 2 Relative Humidity and Dew Point; Adiabatics
Total questions: 21
Worksheet time: 14mins
Which type of air holds more water
warm
cold
hot
cool
Where can you find water vapor in the air?
only in clouds
only as rain
everywhere
As the air temperature increases, the air's capacity for water vapor:
increases
decreases
remains the same
is unrelated to air temperature and can either increase or decrease
What is relative humidity?
humidity that is related to other humidity
condensation
clouds
the amount of water in the air compared to the amount of water the air can hold - a ratio
The time of day when the relative humidity reaches a maximum value is usually
at the time when the air temperature is highest (mid/late afternoon)
in the evening (just before sunset)
at the time when the air temperature is lowest (just before sunrise)
just after sunrise
The temperature to which air must be cooled in order to become saturated is the:
Relative Humidity
Mixing Ratio
Dew Point Temperature
Wet-bulb Temperature
Sponge Analogy (holding water): Which sponge illustrates warm air?
Large Sponge
Medium Sponge
Small Sponge
All sponges would hold the same amount of water (so all the same)
If the air is only holding one-third as much moisture as it can possibly hold, what is the relative humidity?
50%
25%
33%
67%
What is happening to AIR TEMPERATURE when air is rising in the troposphere?
It is cooling
It is warming
It is staying the same temperature
Air pressure is decreasing
As a parcel of air rises upward in the troposphere, the AIR PRESSURE upon that parcel is:
Increasing
Staying constant
Decreasing
Is the air typically colder at the top or bottom of a mountain?
Bottom
Top
If the air temperature cools, but the TOTAL amount of water vapor in the air stays the same, what will happen to the RELATIVE humidity?
relative humidity will decrease
relative humidity will increase
relative humidity will stay the same
As an air mass moves over a mountain (orogenic boundary), the rising air will:
cool due to expansion
cool due to compression
warm due to expansion
warm due to compression
Compare the Lapse 'Rate' for arrows 1 + 2 in the picture. In which case do we find air cooling (losing temperature) of 10oC/1km?
Arrow 1
Arrow 2
Arrow 3
Arrows 1 + 3
As air FALLS when moving over a mountain (#3 in the picture), the descending air is:
warming due to compression
decreasing in its relative humidity due to warming
creating desert conditions
All answers are correct
Based on the numbers on the arrows, which of the following is FALSE?
1 shows air rising and cooling at the DALR
2 shows air rising and cooling at the WALR
3 show air falling/descending and warming at the DALR
We can find precipitation at ALL numbers 1, 2, and 3
Based on the arrows in the picture: Which scenario do we find air AT its Dew Point Temperature yet still moving?
Arrow 1 only
Arrow 2 only
Arrow 3 only
All of the arrows (1, 2, + 3)
