what does it mean when contour lines are close together?
Give this one a try later!
the closer the line, the steeper the slope
inversions
Give this one a try later!
usual temperature structure of the lower atmosphere is characterized by a
decrease in temperature with altitude
what are the elements of proper size up and report on conditions?
,Give this one a try later!
size up is the development of a mental picture of what is happening--what
the fire is doing or will do. it is a continuous process that is only concluded
once the fire is controlled.
-what is the fire behavior and rate of spread?
-is the fire spotting?
-where did the fire start?
-what are the weather conditions?
-what is topography and fuel like?
-what are the values at risk?
-are there natural or existing behaviors?
What is the difference between the 10s and 18s?
Give this one a try later!
10s - address safety issues that are not meant to be compromised DO NOT
BREAK THEM
18s - Represent situations with specific hazards to be mitigated (someone
died for each of these situations)
general wind
Give this one a try later!
large scale upper level winds caused by high and low pressure systems
precipitation
,Give this one a try later!
liquid or solid water particles that originate in the atmosphere
mop up
Give this one a try later!
Extinguishing or removing burning material near control lines, felling snags,
and trenching logs to prevent rolling after an area has burned, to make a
fire safe, or to reduce residual smoke.
what drives horizontal movement of air?
Give this one a try later!
wind
methods of heat transfer
Give this one a try later!
conduction, convection, radiation
fuel types
, Give this one a try later!
Grass
Grass-Shrub
Shrub
Timber - Understory
Timber litter
Slash - Blowdown
point of origin
Give this one a try later!
The precise location where a competent ignition source came into contact
with the material first ignited and sustained combustion occurred.
air temperature
Give this one a try later!
the degree of hotness or coldness of the air

Give this one a try later!
The part of a fire's perimeter that is roughly parallel to the
main direction of spread.
