The least critical form of heat transfer that influences rate of spread in a running wildland fire
is. - ANS Conduction
The point to which a combustible material must be heated to produce self sustaining
combustion is known as the - ANS Ignition temperature

ANS True
A fire that advances through canopies of brush and trees is known as a - ANS 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
- ANS Surface fire with torching and spotting
T/F
Upward moving air contracts and warms - ANS False
As air sinks it - ANS Increases in pressure, warms and compresses
Foehn winds can adversely affect wildland fires because they can produce - ANS 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 - ANS A foehn Wind (look this up)
