S-290 FINAL EXAM A 2026 WITH
QUESTIONS AND ANSWERS
T/F Topography can directly and indirectly affect fuels and their availability
for combustion? - correct answer-True
Of the three primary environmental factors that influence fire behavior,
which is the least variable? - correct answer-Topography
The least critical form of heat transfer that influences rate of spread in a
running wild land fire is: - correct answer-Conduction
The point to which a combustible material must be heated to produce self
sustaining combustion is known as the: - correct answer-Ignition
temperature
Fireline intensity is dependent upon: - correct answer-All of the above
T/F Two requirements for long-range spotting are wind and a well
developed convection column: - correct answer-True
, 2 |Page
A fire that advances through canopies of brush and trees is known as a: -
correct answer-Crown fire
Fire is burning in litter on top of the ground, but occasionally carries into
crowns of individual trees, which produces buying embers that start new
fires outside the fire perimeter: - correct answer-Surface fire with torching
and spotting
Fire begins burning into the crowns and spreads through the canopy. There
is a sudden increase in fireline intensity where the fire controls it's
environment. At one point flames can be seen carried high into the
convection column with a whirling motion. - correct answer-Crown fire with
convection column and firewhirls
Fire is consuming the organic materials beneath the surface of the ground
after the main fie has passed through and is spreading on the surface
without flames. Occasionally the fire will ignite areas of unburned fuels on
the surface and short fire runs take place. - correct answer-Ground fire with
smoldering and flare ups
T/F Upward movie air contracts and warms: - correct answer-False
As air sinks, it: - correct answer-Increases in pressure, warms and
compresses
