Q

normal body temperature is 98.6 in f

A

37 celsius

21
Q

One EMR law states that all objects with a temperature above 0 degrees kelvin

A

emit some form of EMR

22
Q

Stephen boltzman equation

A

E refers to the rate of energy emission per square meter

23
Q

stephen boltzman equation

A

Kelvin is used to express T

24
Q

What is the relationship between temperature and wavelength

A

as temperature increases, the dominant wavelength decreases (inverse relationship)

25
Q

what is the relationship between wavelength and energy

A

as energy increases, the dominant wavelength decreases (inverse relationship)

26
Q

the radiative equilibrium temperature of the ground is lower than that of the atmosphere

A

True

27
Q

The greenhouse gases in the atmosphere absorb heat energy

A

True

28
Q

Does the insolation received from the sun have the same dominant wavelength as that subsequently emitted by the earth

A

no

29
Q

Wich portion of the spectrum is primarily responsible for directly heating the atmosphere

A

terrestrial longwave infrared

30
Q

the atmosphere is heated

A

from the bottom up

31
Q

day and night are caused by

A

the rotation of the earth

32
Q

The sun is directly overhead north of 23.5 degrees north latitude

A

once a year

33
Q

The sun crosses the equator

A

twice a year

34
Q

the upward motion of air in response to heating is referred to as

A

convection

35
Q

about 30 percent of the insolation reaching the earth is

A

reflected and not absorbed

36
Q

insolation from the sun occurs primarily in th

A

UV region of the EM spectrum

37
Q

when energy is absorbed and reradiated from the

earths surface it is reradiated as

A

longwave radiation

38
Q

water has a higher specific heat than land and therefore heats

A

more slowly

39
Q

because water has a higher heat capacity than land

A

it cools more slowly

40
Q

cities in the interior of continents have

A

larger temp ranges than cities along the coast at the same latitude

41
Q

the greater the albedo of a surface the less it is heated by insolation

A

True

42
Q

the atmosphere is heated

A

from the bottom up, not directly by solar radiation

43
Q

The visible portion of the spectrum constitutes a

A

small portion of the spectrum

44
Q

the rate of change in temperature from the surface downward is more rapid in soil than water

A

true

45
Q

london has warmer winters than new york

A

because of the ocean currents

46
Q

vegetation, even when it is darker than the surrounding landscape

A

acts to cool the surrounding air temperature

47
Q

on the summer solstice the sun never sets for positions north of the arctic circle

A

True

48
Q

The ocean stores more heat energy than the atmosphere

A

True

49
Q

ocean currents have little effect on coastal temps

A

False
