Cards

Term
Abiotic
Definition
Characterized by the absence of life
Term
Biotic
Definition
Pertaining to Life
Term
Energy Transfer Mechanisms
Definition
Radiation, Conduction, Convection, Latent heat, High Energy chemical bonds (1-4 are abiotic, 5 is biotic
Term
Radiant Energy
Definition
Transfer of energy via electromagnetic spectrum. Direct (line of sight). Fast. Every object in the world transmits it.
Term
Three properties of Radiant Energy
Definition
Quality, Quantity, Duration
Term
Quality (Radiant Energy)
Definition
The relative mix of wavelengths in an energy source. Dictates how much energy and who can use it.
Term
which wavelengths have more energy. Smaller or Larger?
Definition
Smaller
Term
Conduction
Definition
Molecule to molecule contact through solids. Slow.
Term
Convection
Definition
Like conduction but through a moving medium. Molecular contact and movement of molecules. Faster than conduction, slower than radiation.
Term
Latent Heat Exhange
Definition
Energy involved in phase change of something (for us, water)
Term
What factors reduce solar energy on the earth?
Definition
Latitude
Season
Time of Day
Slope and Aspect
Stuff i the way (atmospheric reductions)
Term
Atmospheric Reductions
Definition
Every molecule of the atmosphere acts independently, scattering, absorbing, or transmitting E
Our atmosphere preferentially scatters short wavelengths (blues) and absorbs long wavelengths. (Why the sky is blue)
Term
Conductive Capacity
Definition
Calculate by Thermal Conductivity of an objece and specific heat of an object. Allows you to determine relative strength of two arrows in an E budget.
Term
Transpiration
Definition
Movement of water from liquid to vapor off a specialized surface- a leaf
Term
How to lift air
Definition
Cyclonic(non-front,frontal), orographic, convective
Term
Cyclonic
Definition
Cyclones (counterclockwise movement of air). Earths spin, differential heating and cooling = air movement
Term
Warm front
Definition
Shallow angle = greater intensity, less duration than frontal
Term
Cold Front
Definition
Steep angle = Even greater intensity and less duration
Term
Occluded front
Definition
Cold air more dense, so gets pushed faster (easier to push water than air)
Term
Water Balance Equation
Definition
PPT=ET+Q+DeltaS
Precipitation=Evapotranspiration+Discharge+Change in Storage
