What problem besides pollution can threaten a Florida aquifer?

  • A permanent mountain snowpack
  • Volcanic ashfall everywhere
  • Overly high desert sand dunes
  • Excessive groundwater withdrawals
Correct answer(s):
  • Excessive groundwater withdrawals

How can saltwater intrusion affect coastal Florida communities?

  • It guarantees cleaner drinking water
  • It creates new mountain springs
  • It permanently removes ocean salt
  • It can reduce the usability of freshwater supplies
Correct answer(s):
  • It can reduce the usability of freshwater supplies

Why are mangroves valuable along sheltered South Florida coasts?

  • They produce drinking water directly
  • They grow only above the snow line
  • They provide habitat and help stabilize shorelines
  • They prevent every hurricane
Correct answer(s):
  • They provide habitat and help stabilize shorelines

Which statement accurately compares alligators and American crocodiles in South Florida?

  • They are the same species
  • Neither occurs in Florida
  • They may use different habitats in the Everglades region
  • Both live only in freshwater mountain lakes
Correct answer(s):
  • They may use different habitats in the Everglades region

Why must Everglades restoration involve land outside a national park?

  • Canals affect only fenced areas
  • The park includes the entire watershed
  • Water and wildlife systems cross park boundaries
  • Rain never falls outside the park
Correct answer(s):
  • Water and wildlife systems cross park boundaries

What can upstream changes around Lake Okeechobee influence?

  • Only the state of Alaska
  • No ecosystems outside a single canal
  • Downstream wetlands and water conditions
  • Only road traffic in Jacksonville
Correct answer(s):
  • Downstream wetlands and water conditions

Why does irrigation planning matter to Florida agriculture?

  • Soil never loses moisture in Florida
  • Only forests use freshwater
  • Crops need reliable and managed water supplies
  • Irrigation has no effect on crops
Correct answer(s):
  • Crops need reliable and managed water supplies

What exactly is storm surge?

  • Seawater pushed onto land by a storm
  • Freshwater pumped from an aquifer
  • The number of hurricane warnings
  • Rainwater collecting in a river
Correct answer(s):
  • Seawater pushed onto land by a storm

How should hurricane wind damage and inland flooding be understood?

  • As the same measurement in every case
  • As events unrelated to hurricanes
  • As separate hazards requiring different assessments
  • As risks only for coastal islands
Correct answer(s):
  • As separate hazards requiring different assessments

Can Atlantic tropical cyclones form outside June through November?

  • Only if Florida has snow
  • No, atmospheric laws forbid it
  • Only during leap years
  • Yes, occasionally
Correct answer(s):
  • Yes, occasionally

Which process forms karst features in Florida’s limestone?

  • Lava erupting from active volcanoes
  • Freezing of a permanent ice cap
  • Dissolution of soluble rock by water
  • Wind carving sandstone in a desert
Correct answer(s):
  • Dissolution of soluble rock by water

How can groundwater travel through Florida’s carbonate rocks?

  • Through solid rock with no pores at all
  • Through cracks and cavities
  • Only as surface ocean waves
  • Only across paved roads
Correct answer(s):
  • Through cracks and cavities

What is an aquifer?

  • Rock or sediment that stores and transmits groundwater
  • A high-altitude river source
  • A type of tropical storm
  • An artificial offshore reef
Correct answer(s):
  • Rock or sediment that stores and transmits groundwater

Which geographic statement about the Floridan aquifer system is correct?

  • It is a single surface lake
  • It extends into neighboring southeastern states
  • It exists only in Key West
  • It ends exactly at Florida’s political borders
Correct answer(s):
  • It extends into neighboring southeastern states

Why can groundwater pollution be hard to detect by looking at a river?

  • Pollution always changes river color immediately
  • All groundwater is naturally sterile
  • Contamination may occur underground even if surface water appears normal
  • Aquifers are completely separated from human activity
Correct answer(s):
  • Contamination may occur underground even if surface water appears normal

What must wetland restoration consider besides the total amount of water?

  • When and where water flows
  • The number of highways outside the watershed
  • Only the height of nearby buildings
  • Only the number of tourists
Correct answer(s):
  • When and where water flows

Why can different sources report different lengths for Florida’s coastline?

  • Florida changes continents each year
  • Coastlines have a fixed length under every method
  • They use different shoreline definitions and map detail
  • Islands are never counted in any method
Correct answer(s):
  • They use different shoreline definitions and map detail

What does saltwater intrusion mean?

  • A river becomes permanently dry
  • Freshwater freezes into a glacier
  • An ocean current turns into a river
  • Saline water enters a freshwater system
Correct answer(s):
  • Saline water enters a freshwater system
