PCB 3043C Exam 1 || 100% Faultless Answers.
Ecology correct answers Scientific study of interactions among organisms and between
organisms and their environment
Holism correct answers a concept that considers the whole person; the whole is greater than the
sum of its parts. Ecosystem
Reductionism correct answers the reduction of complex systems to simpler components that are
more manageable to study
statistical model correct answers a mathematical description of data used to predict the value of a
dependent variable on an independent variable
analytical model correct answers model that is created with mathematical formulas to solve
mathematically.
climate correct answers The average weather conditions in an area over a long period of time
Dependent on: temperature, moisture
weather correct answers the state of the atmosphere at a place and time as regards meteorology.
Considers extreme weather, dependent on unequal heating
unequal heating correct answers The way in which parts of Earth's surface get heated unequally
by the sun's radiation, causes winds by changing air temperature, density, and pressure
Causes of unequal heating correct answers Sun angle: axial tilt causes different areas of the earth
to be exposed to sun
Albedo
Albedo correct answers the proportion of the incident light or radiation that is reflected by a
surface vs absorbed
Forest have decreased reflectivity, while snow has increased reflectivity (in %)
solar radiation correct answers Transmission of energy from the sun in the form of
electromagnetic waves.
More absorbed, less reflected increases heating
Less absorbed, more reflected decreases heating
Transmission correct answers the passage of light through an object
greenhouse gases correct answers Gas in the atmosphere that absorbs energy and emits radiant
energy within the thermal infrared range. Caused by albedo
Water vapor is the most significant.
, high specific heat correct answers The ability of water to resist changes in temperature. Can store
large amounts. Important in weather and climate
high heat of vaporization correct answers The amount of heat necessary to cause a phase
transition between a liquid and a gas; Large a mount of heat is needed to vaporize liquid
Water properties correct answers High heat capacity; cohesive and adhesive; frozen water is less
dense then liquid water
humidity correct answers a measure of the amount of water vapor in the air
absolute humidity correct answers The mass of water vapor contained in a certain volume of air.
(g H2O m^3/air)
Relative Humidity (RH) correct answers the amount of water vapor present in air expressed as a
percentage of the amount needed for saturation vapor pressure. @ saturation vapor pressure,
RH= 100%
relative humidity equation correct answers (Absolute Humidity)actual vapor density/ saturation
vapor pressure x100%
saturation vapor pressure correct answers Maximum amount of water air will hold (warm air
hold more water than cold air)
Saturation vapor pressure ___ as temperature increases. correct answers increases (higher temp,
faster moving particles)
Saturation vapor pressure ___ as temperature decreases. correct answers Decreases (lower temp,
slower moving particles)
Density _____ as temperature increases. correct answers decreases
Density _____ as temperature decreases. correct answers increases
Humidity Dynamics correct answers Cold air cannot hold as much as water
If the air cools bellow the saturation vapor pressure, the moisture condenses, causing __ and __.
correct answers Clouds of precipitation
dew point temperature correct answers The temperature at which air becomes saturated; to which
a parcel of air would need to be cooled to reach saturation
latent heat of condensation correct answers the energy/heat released when water vapor condenses
to liquid water. Keeps temperature from going lower than possible
Ecology correct answers Scientific study of interactions among organisms and between
organisms and their environment
