Answer: Temperature, relative humidity, atmospheric stability, wind speed
and direction, and precipitation.
◍ What topographic factors are important to wildland fire behavior?.
Answer: Elevation, position on slope, aspect, shape of the country, and
steepness of slope.
◍ What fuel factors are important to wildland fire behavior?.
Answer: Fuel loading, size and shape, compactness, horizontal continuity,
vertical continuity, and chemical content.
◍ How is heat transferred via conduction?.
Answer: The transfer of heat from one molecule to another.

Answer: 1) Weather2) Topography 3) Fuels
,◍ How is heat transferred via convection?.
Answer: The transfer of heat from the motion of air.
◍ How is heat transferred via radiation?.
Answer: The transfer of heat by electromagnetic waves.
◍ The least critical form of heat transfer that influences rate of spread in a
running wildland fire is..
Answer: Conduction
◍ What are the three methods of mass transport for firebrands?.
Answer: Convection, wind, and gravity.

sustaining combustion is known as the.
Answer: Ignition temperature
◍ How many feet are in one chain?.
Answer: 66 feet.
◍ Define spotting in the context of wildland fire..
Answer: Fire producing sparks or embers that are carried by the wind and
start new fires beyond the main fire.
◍ What factors primarily affect fireline intensity?.
Answer: Fuel sizeFuel moistureFuel temperatureFuel compactness and
arrangementALL OF THE ABOVE
◍ T/FTwo 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
◍ What is a surface fire?.
Answer: A fire that burns surface litter, debris, and small vegetation.
◍ What is a running fire?.
Answer: A fire spreading rapidly with a well-defined head.
◍ What is a creeping fire?.
Answer: A fire burning with a low flame and spreading slowly.
◍ What is a smoldering fire?.
Answer: A fire burning without flame and barely spreading.
◍ What is a crown fire?.
Answer: A fire that advances from top-to-top of trees or shrubs
independently of the surface fire.
◍ T/FUpward 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
◍ What is a ground fire?.
Answer: A fire that consumes the organic material beneath the surface litter.
◍ What is a flare-up?.
Answer: A sudden acceleration of fire spread or intensity of relatively short
duration.
◍ 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)
◍ What is a fire-whirl?.
Answer: A spinning, moving column of ascending air rising within a vortex,
