Exam 1 CONT. Flashcards
Energy from the interior of the Earth drives the atmosphere and generates weather.
False
THe energy received at the earth is produced by nuclear fusion in the sun
True
Electromagnetic radiation requires a medium in which to travel
False
All wavelengths of electromagnetic radiation have the same amount of energy associated with them
False
GAmma rays are less energetic than visible light
false
Infrared radiation is often called “thermal radiation” because it is so effective at heating most forms of matter such as soil, water, and the atmosphere
True
Radio waves are dangerous forms of radiation becasue they are so long
False
The Farenheit scale defines the freezing point and boiling point of water as
32 degrees and 212 degrees
the Celsius scale defines these values as
0 degrees and 100 degrees
on the farenheit scale there are 180 degrees between
freezing and boiling water
celsius scale there are
100 degrees between freezing and boiling
celsius degrees are
larger than farenheit
F—->C
(f-32)/1.8
C—->F
(1.8 X c) + 32
Change in temp
F/1.8
Change in temp
c X 1.8
Absolute zero on the Kelvin scale
0
absolute zero on celsius scale
-273
absolute zero on farenheit
-459.4
normal body temperature is 98.6 in f
37 celsius
One EMR law states that all objects with a temperature above 0 degrees kelvin
emit some form of EMR
Stephen boltzman equation
E refers to the rate of energy emission per square meter
stephen boltzman equation
Kelvin is used to express T
What is the relationship between temperature and wavelength
as temperature increases, the dominant wavelength decreases (inverse relationship)
what is the relationship between wavelength and energy
as energy increases, the dominant wavelength decreases (inverse relationship)
the radiative equilibrium temperature of the ground is lower than that of the atmosphere
True
The greenhouse gases in the atmosphere absorb heat energy
True
Does the insolation received from the sun have the same dominant wavelength as that subsequently emitted by the earth
no
Wich portion of the spectrum is primarily responsible for directly heating the atmosphere
terrestrial longwave infrared
the atmosphere is heated
from the bottom up
day and night are caused by
the rotation of the earth
The sun is directly overhead north of 23.5 degrees north latitude
once a year
The sun crosses the equator
twice a year
the upward motion of air in response to heating is referred to as
convection
about 30 percent of the insolation reaching the earth is
reflected and not absorbed
insolation from the sun occurs primarily in th
UV region of the EM spectrum
when energy is absorbed and reradiated from the
earths surface it is reradiated as
longwave radiation
water has a higher specific heat than land and therefore heats
more slowly
because water has a higher heat capacity than land
it cools more slowly
cities in the interior of continents have
larger temp ranges than cities along the coast at the same latitude
the greater the albedo of a surface the less it is heated by insolation
True
the atmosphere is heated
from the bottom up, not directly by solar radiation
The visible portion of the spectrum constitutes a
small portion of the spectrum
the rate of change in temperature from the surface downward is more rapid in soil than water
true
london has warmer winters than new york
because of the ocean currents
vegetation, even when it is darker than the surrounding landscape
acts to cool the surrounding air temperature
on the summer solstice the sun never sets for positions north of the arctic circle
True
The ocean stores more heat energy than the atmosphere
True
ocean currents have little effect on coastal temps
False
