◉Of the three environmental factors that influence fire behavior,
which is the least variable. Answer: topography
◉What are the 3 Environmental Factors that influence Fire
Behavior?. Answer: 1) Weather
2) Topography
3) Fuels
◉The least critical form of heat transfer that influences rate of
spread in a running wildland fire is.. Answer: Conduction
◉The point to which a combustible material must be heated to
produce self sustaining combustion is known as the. Answer:
Ignition temperature
◉What factors primarily affect fireline intensity?. Answer: Fuel size
Fuel moisture
Fuel temperature
,Fuel compactness and arrangement
ALL OF THE ABOVE
◉T/F
Two requirements for long range spotting are wind and a well
developed convection column.. Answer: True
◉A fire that advances through canopies of brush and trees is known
as a. Answer: Crown fire
◉Fire is burning in litter on top of the ground, but occasionally
carries into the crowns of individual trees, which produces burning
embers that start new fires outside the fire perimeter. Answer:
Surface fire with torching and spotting
◉T/F
Upward moving air contracts and warms. Answer: False
◉As air sinks it. Answer: Increases in pressure, warms and
compresses
, ◉Foehn winds can adversely affect wildland fires because they can
produce. Answer: Strong winds, warmer temperatures, and very low
relative humidity
◉When stable air is forced over a mountain range, and then
descends the leeward slope as dry, warmed air, it is called. Answer: A
foehn Wind (look this up)
◉T/F
Bends in canyons are likely places for eddies to form. Answer: True
◉Local winds are best described as. Answer: Small scale convective
winds of local origin caused by differences in heating and cooling
◉East, Mono, Santa Ana, and Chinook are all examples of
________________________.. Answer: Foehn Winds
◉T/F
Air flows clockwise around low pressure systems and
counterclockwise around high pressure systems. Answer: False.
Counterclockwise in Low Pressures
