Total questions: 15
Worksheet time: 8mins
A discrete event in time that disrupts ecosystem structure and changes resources, soil, or the physical environment is the definition of:
disturbance
drought
succession
diatom
proxy data
Proxy evidence or proxy data is:
preserved "clues" about what past climates were like
useful in determining past climates
useful in determining past fire history
All of these describe proxy data.
Of the 2 images displayed, which is likely the map of human-caused wildfire, and why do you think that?
the map on the left; there are large sections empty in SE Washington and western California where there aren't humans
the map on the left; the large areas on the west coast (in Washington and California) correspond to areas where there are burn bans in place
the map on the right; we see fires along the coast (in Washington, Oregon and California), where there typically aren't thunderstorms
the map on the left; Nevada has hardly any fires which only happens because no people live there
Which of the following is NOT a way disturbances are classified?
according to their spatial extent
according to their frequency
according to their intensity
according to the date in history on which they occurred
according to their severity
What 3 things make up the fire triangle?
fuel, carbon dioxide, heat
oxygen, fuel, heat
oxygen, fuel, vegetation
carbon dioxide, heat, trigger
____ succession is likely to take place after a wildfire.
Primary
Preliminary
Secondary
Artificial
Which of these is likely to be a pioneer species after a wildfire?
lodgepole pine tree
whitetail deer
gray squirrel
sugar maple tree
Which of the following is the correct pairing of a fire control with how it controls wildfires?
Fuel: the more people that live in an area, the less fuel the fire has to burn
Topography: the side of the mountain facing the sun is less susceptible to dry conditions
Weather: the wind direction, temperature and humidity will control where the fire moves
All are correct pairings.
Which of the following is NOT a secondary hazard related to wildfires?
loss of soil (erosion)
increased runoff
hunger
landslides
loss of vegetation
How can wildfire hazards be minimized?
through education campaigns like Smokey the Bear
through red flag warnings and burn bans
by reconstructing past fire histories using charcoal data
through use of prescribed burns to reduce the vegetation in an area
All of these are viable options for reducing wildfire hazards.
What are the 3 main types of drought?
meteorological, hydrological, agricultural
meteorological, agricultural, human-induced
short-term, long-term, intermediate
short-lived, extensive, devastating
Which of the following maps was the drought map for this November (when we looked at drought maps in class)?
When looking at drought forecast maps in class, were there any areas of the country that were likely to improve in drought conditions in the near future?
the west coast states (WA, OR)
the northeast states (MA, CT, ME)
the northern Plains states (ND, SD)
No, everybody was expected to get worse.
When we were looking at drought maps in class, who had elevated fire risk at that time?
small portions of California
the entire Central Plains of the U.S.
only northern Wisconsin
southeastern states, especially Florida
only a small portion of the central East coast (near Maryland)
Which of the following is NOT a negative effect related to drought?
agriculture loss
reduction in energy production
famine and war
disease
All are negative effects related to drought.
