GROUND COVER FIRE FIGHTING
EXAM 2025 QUESTIONS AND ANSWERS
Spinning vortex column of ascending hot air and gases rising from a fire and carrying aloft
smoke, debris, and flame. Range in size from less than one foot to over 500 feet in diameter.
(Ch 1) - ANS Fire Whirl
The distance between the flame tip and the midpoint of the flame depth at the base of the
flame, an indicator of fire intensity. (Ch 1) - ANS Flame Length
transfer of heat in straight lines through a gas or vacuum other than by heating of the
intervening space. (Ch 1) - ANS Radiation
The relative activity of a fire in extending its horizontal dimensions. It is expressed as a rate of
increase of the total perimeter of the fire. Usually it is expressed in chains or acres per hour for
a specfic period in the fire's history. (Ch 1) - ANS Rate of Spread
Behavior of a fire producing sparks or embers that are carried by the wind and which start new
fires beyond the zone of direct ignition by the main fire. (Ch 1) - ANS Spotting
Burning of the foliage of a single tree or group of trees or shrubs from the bottom up. (Ch 1) -
ANS Torching

, Fires that burn in the layer of dead organic matter that generally covrs the soil in forested
areas. Slow moving, smoldering fires that can go undetected for months before they enter a
flaming stage(Ch 1) - ANS Ground fires
The most common type of ground cover fire, burning on the soil surface consuming low-lying
grass, shrubs, and other vegetation. (Ch 1) - ANS Surface fires
Wind-driven, high intensity fires that move through the tree tops of heavily forested areas. (Ch
1) - ANS Crown Fires
Needles, duff, twigs, grass, field crops, brush up to 6 feet in height, downed limbs, logging slash,
and small trees on or immediately adjacent to the surface of the ground. (Ch 1) - ANS Surface
fuels
Suspended and upright fuels, brush over 6 ft, physically separate from ground and air can
circulate freely between them. (Ch 1) - ANS Aerial fuels
The most critical weather element affecting wildland fire behavior. (Ch 1) - ANS Wind
Local winds that develop in hilly and mountainous terrain where the differences in heating and
cooling occur. (Ch 1) - ANS Slope winds
Develope as air in the valleys, draws, and hillsides become warmer that the air at the top of the
slope and begins to rise. Speeds generally between 3 and 8 mph and can be gusty. (Ch 1) -
ANS Upslope winds
Generally occur after midnight and speeds range from 2 to 5 mph. (Ch 1) - ANS Downslope
