S-290 Intermediate Wildland Fire Behavior/quick
and easy pass 2025
A fire that advances through canopies of brush and trees is known as a - Crown fire
A fuel model is described as - A set of numbers that define fuel input for use in the
surface fire spread model
A ground fire has burned under a thick stand of pine reproduction. What potential problems
could occur - A reburn possibly involving the canopies
A slope wind is caused by - warm air rising and cold air settling
A slope wind is caused by - Warm air rising and cold air settling
According to the hauling chart, a Fire that can generally be attacked at the head or flanks by
persons using hand tools have flame lengths that are ____________. - 4 feet or less.
As air sinks it - Increases in pressure, warms and compresses
Aspect affects fuels and their availability to burn because - Southwest sites provide drier
sites
Vegetation type and fuel moisture changes by aspect
Shading on northern aspects can increase relative humidity
ALL OF THE ABOVE
, Aspect is an important factor regarding temperature - true
Available fuels are - All dead and live fuels that will ignite and continue to burn
Cloud cover has no affect on temperature - False
Cloudiness has little affect on relative humidity and temperature - False
Continuous fine fuels, heavy fuel loadings, ladder fuels, crown spacing, and special fuel
situations are fuel characteristics that should NOT be monitored - False
Crown fire development depends on crown flammability along with adequate surface to crown
and crown to crown heat transfer - True
Dry environments se larger or smaller temperature ranges than moist environments -
larger
East, Mono, Santa Ana, and Chinook are all examples of ________________________. -
Foehn Winds
En route to a fire you notice that smoke from a burning haystack rises straight up. What could
this indicate on a wildland fire - An unstable atmosphere may increase fire activity
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 -
Surface fire with torching and spotting
