answer must be between and ]
Scores

13. 76 996 2 23/ 73 0.25 What was the barometric pressure three hours ago?
$500 76
996 2
23/ 73
0.25
What was the barometric
pressure three hours ago?
Scores

14. 997.3 mb $500 The barometric pressure is 999.6 mb currently (996).
The barometric trend was +2.3mb over the last three hours.
Therefore, the barometric pressure has gone up.
Three hours ago the air pressure was lower than it is now.
Therefore, subtract the barometric trend from the pressure.
999.6 – 2.3 = 997.3
Scores

15. $100
The dew point and relative humidity when the dry-bulb is 24°C and the wet-bulb is 9°C.

16. $100
What is -18°C
and 4%?
[Find the difference first between the dry-bulb and the wet-bulb (24 – 9 = 15). Then go to column 15 on page 12 of the Earth Science Reference Tables and go down to the row for 24°C.]
Scores

17. $200
The relative humidity when the air temperature is 18°C and the dewpoint is 9°C.

18. $200
What is 56%?
[First go to the Dew Point Chart on page 12 of the Earth Science Reference Tables. Find the air temperature (dry-bulb) row for 18°C, then go across until you find the dewpoint temperature of 9°C (column 5).
Stay in column 5 and move down to the Relative Humidity Chart. Go down to the dry-bulb temperature of 18°C and the relative humidity is 56%.]
Scores

19. $300

24. The relationship between dew point and air pressure
$500
The relationship between
dew point and air pressure

25. $500
What is indirect?
(as the air becomes more moist (greater dew point),
the air becomes less dense)
Scores

26. The relationship between the ability of the air to hold water
$100
The relationship between
temperature
and
the ability of the air to hold water

27. (warm air can hold more water than cold air)
$100
What is direct?
(warm air can hold more water than cold air)
Scores

28. The relationship between
$200
The relationship between
air pressure
and
air density

29. What is direct? $200 (more dense air has a greater pressure and sinks
(high pressure, high density))
Scores

30. The relationship between
$300
The relationship between
altitude
and
air pressure

31. $300 What is indirect? (as you increase your altitude
(like going up on top of a mountain),
the air pressure decreases)
Scores

32. The relationship between
$400
The relationship between
air pressure
and
temperature

33. $400
What is indirect?
(as the temperature increases, the air becomes less dense
and therefore, a lower pressure)
Scores

34. The relationship between
$500
The relationship between
relative humidity
and
temperature

35. $500
What is indirect?
(as long as the actual amount of water in the air stays constant, the relative humidity will decrease as temperature increases)
