Cards

Term
global warming
Definition
the increase in average global temperatures
Term
greenhouse gases
Definition
those gases capable of absorbing and re-emitting infrared radiation
(See page(s) 102)
Term
greenhouse effect
Definition
process by which atmospheric gases trap and return a major portion of the heat (infrared radiation) radiated by the Earth
(See page(s) 103)
Term
enhanced greenhouse effect"
Definition
process in which atmospheric gases trap and return more than 80% of the heat energy radiated by the Earth
(See page(s) 105)
Term
tetrahedron
Definition
four-cornered figure with four equal triangular sides
(See page(s) 111)
Term
wavenumbers
Definition
numbers often expressed in units of cm-1 and used on the x-axis of an infrared spectrum; inversely proportional to wavelength
(See page(s) 116)
Term
quantized
Definition
noncontinuous energy distribution that consists of many individual steps
(See page(s) 71, 118)
Term
carbon sink
Definition
natural reservoir that removes CO2 from the atmosphere
(See page(s) 121)
Term
atomic mass
Definition
average mass of an atom of an element compared with an atomic mass of exactly 12 amu for carbon-12 121; mass (in grams) of the same number of atoms found in exactly 12 g of carbon-12
(See page(s) 122)
Term
Avogadro's number
Definition
number of atoms in exactly 12 g of carbon-12
(See page(s) 122)
Term
mole
Definition
an Avogadro's number of objects
(See page(s) 123)
Term
molar mass
Definition
mass of one Avogadro's number, or "mole," of whatever particles are specified
(See page(s) 124)
Term
global atmospheric lifetime
Definition
time required for a gas added to the atmosphere to be removed. Also referred to as the "turnover time."
(See page(s) 126)
Term
anaerobic bacteria
Definition
bacteria that can function without the use of molecular oxygen
(See page(s) 127)
Term
albedo
Definition
ratio of electromagnetic radiation reflected relative to the amount of radiation incident on a surface
(See page(s) 131)
Term
forcings
Definition
factors that affect the annual global mean surface temperature
(See page(s) 131)
Term
sequestration
Definition
process of keeping some things apart. Chemically this is accomplished by forming stable bonds between the sequestering agent and the substance "trapped."
