What is the layer of atmosphere that we live our lives in?
Troposphere
Stratosphere
Ozone layer
A layer that is 100% oxygen
As a parcel of air rises upward in the troposphere, the AIR PRESSURE upon that parcel is:
Increasing
Staying constant
Decreasing
Air that is rising in the troposphere is:
Warming up (increasing in temp)
Cooling down (decreasing in temp)
Is immediately reaching its Dew Point Temperature
Staying at the same temperature (and pressure) as it rises
Cold air holds _______ water vapor than hot air.
less
more
the same amount of
As the air temperature decreases, the air's capacity for water vapor:
increases
decreases
remains the same
is unrelated to air temperature and can either increase or decrease
Hot air holds _______ water vapor than cool air.
less
more
the same amount of
If air is fully saturated with water and has reached its Dew Point Temperature, that means:
the air is full of water
the air is partially full of water
it's amount of water vapor in the atmosphere right now
how much liquid water it potentially can hold
A location with a RH of 95% has _______ water vapor than a location with 10% RH.
slightly less
the same amount of
significantly more
slightly more
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
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
Why does DEW form on grass and surfaces overnight and leave the surface damp?
It must have experienced heavy rain that night
Humid air contacts cold ground and condenses
Dry air contacts a warm surface/ground
Moisture is squeezed out of plants due to the air pressure
If a parcel of air has a temperature of 20oC and contains 7 grams of water vapor, what is its RH (Relative Humidity)?
50%
25%
75%
100%
If a parcel of air is warmed, what is happening to its RH as it is warming?
relative humidity will decrease
relative humidity will increase
relative humidity will stay the same
As an air mass moves upward (forced aloft), the air will:
cool due to expansion
cool due to compression
warm due to expansion
warm due to compression
Based on the numbers on the arrows, which of the following is TRUE?
1 shows air rising and cooling
2 shows air rising and cooling
3 show air falling/descending and warming
All answers are true
Based on the numbers on the arrows, which of the following is FALSE?
1 shows air rising and cooling at the DALR (10oC / 1000m)
2 shows air rising and cooling (10oC / 1000m)
3 show air falling/descending and warming (10oC / 1000m)
Air that is rising and falling is changing in its temperature and relative humidity
