Combined albedo of Earth and the atmosphere is approx ____ %?

A

30%

18
Q

Clouds strongly emit infrared radiation back to the Earths surface, T or F?

A

True

19
Q

Suppose last night was clear and calm. Tonight’s forecast indicates that low clouds and fog will be present. From this you would conclude that tonight’s minimum temperature will be ?

A

Higher than last nights minimum temperature

20
Q

The heat energy released when water vapor changes to a liquid is called?

A

Latent heat condensation

21
Q

The albedo of the moon is 7%, this means that?

A

7 % of sunlight striking the moon is reflected

22
Q

Without the atmosphere greenhouse effect, the average surface temperature would be ___?

A

Lower than at present

23
Q

The amount of heat energy required to bring about a change in temperature in a substance is called?

A

Heat capacity

24
Q

Which principle bets describes why melting occurs first in snow around tree trunks?

A

Snow is a good absorber of infrared energy

25
Q

When water vapor evaporates, latent heat is reversed into the atmosphere, this provides a tremendous amount of heat in storms, such as thunderstorms and hurricanes. True or False?

A

False

26
Q

Earth emits radiation with greatest intensity at ?

A

Infrared wavelengths

27
Q

The atmosphere near earths surface is “heated from below” by heat energy from earths interior. True or false?

A

False

28
Q

The main process responsible for warming in the lower atmosphere is?

A

The absorption of infrared radiation

29
Q

The sun emits its greatest intensity of radiation in ?

A

The visible portion of the spectrum

30
Q

What determines the type (wave length) and amount of radiation an object emits?

A

Temperature

31
Q

Sunlight that bounces off a surface is said to be ——- from the surface

A

Reflected

32
Q

A vertical exchange of heat is called?

A

Convention

33
Q

As we apply Newtonian principles and analyze the way the suns energy travels through the atmosphere we can say that solar radiation reaches earths surface as?

A

Ultra violet, visible, and infrared

34
Q

Often before sunrise on a clear, calm morning, the temperature falls dramatically in the absence of parked cars, even when the air temperature is above freezing because the tops of cars are cooling by a loss of?

A

Radiation

35
Q

The rising air bubbles from convection are known as
