Radiation Gains
1. As temperature at a location increases, the air pressure decreases .
2. As temperature at a location decreases, the air pressure increases .
3. Light rays pass through window glass by the process of radiation .
4. A dull, black surface absorbs most sunlight.
5. A shiny, white surface reflects most sunlight.
6. When ice is placed in a glass of room temperature water, the ice gains heat and the water loses heat.
7. The transfer of energy by air currents in the atmosphere is called convection .
8- 15: Circle the correct answer for each diagram:

Temperature: WARM / COOL
Tilt of the Earth: TOWARDS / AWAY
Angle of Insolation: HIGH / LOW
Season: SUMMER / WINTER
Temperature: WARM / COOL

16-17: Label each box with an
H or
L
to indicate which pressure system is represented:
D 18. Between which two letters will the wind speed be the fastest?
A
B
C
A and B
19. How can you tell?
It’s where the isobars are closest together .
20. What device is shown at the right? Mercury Barometer
21. What does it measure? Air Pressure Mercury
22. What happens to air pressure as altitude increases? Air pressure decreases, because at higher elevations there is less air pushing down from above.
23. What happens to air pressure as humidity increases? Air pressure decreases because water vapor takes the place of air molecules and is less massive than air.
24. What happens to air pressure as temperature increases? Air pressure decreases because the air molecules in warm air are far apart lowering the density.
25. Circle the description of vertical motion of air in a high pressure system: [ sinking air / rising air ]
26. Circle the description of vertical motion of air in a low pressure system: [ sinking air / rising air
]
28. List the characteristics of low pressure. 27. List the characteristics of high pressure.
-Cooler Temperatures & Dry Air -Warmer Temperatures & Humid Air
-Sunny, clear weather -Cloudy, rainy weather
-Rising Barometer -Falling Barometer
-Air moving down, clockwise and out -Air moving in, counterclockwise and up
