What unpredictable wind is more likely to occur near intersecting drainages during the
afternoon with unstable air? - answer Wind Eddies
What can influence the curing of fuels as well as the intensity and spread of wildland
fires? - answer Shape of the country
List 2 methods to determine slope - answer1. Clinometer
2. Measurement (with a stick or on a topo map)
When will the WEST aspect expect slope temperature and slope winds be at their
greatest? - answer Evening
When will the EAST aspect expect slope temperature and slope winds be at their
greatest? - answerMidmorning
When will the NORTH aspect expect slope temperature and slope winds be at their
greatest? - answernoon
When will the SOUTH aspect expect slope temperature and slope winds be at their
greatest? - answernoon
True/ False
General winds cannot be modified by topography to form local winds that blow in
different directions. - answerFalse
What is the formula for percent of slope? - answerRise/ Run x 100
What is the percent of the slope for a ridge 1500 feet long with an elevation rise of 300
ft? - answer20%
True/False
The shape of the country can influence the curing of fuels - answerTrue
Can a fuel change be a barrier to fire spread? - answerYes; example: meadow
True/ False
Thunderstorms downdrafts are not a major concern for fires more than 10 miles from
the storm. - answerFalse
What will happen if the wet bulb is not read at its lowest point? - answerThe calculated
RH will be too high
