Climate Change Quiz

Why is the survival of the polar bear population threatened by climate change?

• Warmer temperatures cause the ocean to be more salty preventing polar bears from being able to eat and digest their food.

• Climate change causes temperature to be colder but polar bears are adapted to warmer climate conditions.

• Polar bears live only in the Arctic where sea ice is rapidly increasing due to colder temperatures.

• Polar bears live only in the Arctic where sea ice is rapidly declining due to warmer temperatures.

Which of the following extreme weather events do scientists have the strongest evidence for being influenced by climate change?

• Earthquakes.

• Lightning.

• Heat waves and coastal flooding.

• Tornadoes.

How does climate change significantly impact coral reefs?

• Increased temperatures cause sea levels to drop, which expose coral reefs to the air, drying them out.

• Excess carbon dioxide in the atmosphere dissolves in the ocean causing ocean acidification, which decreases the growth rates and structure of corals.

• Excess carbon dioxide in the atmosphere dissolves in the ocean causing ocean temperatures to decrease which prevents corals from surviving.

• Increased temperatures cause coral reefs to expand in size.

Which of the following describes how seabird populations are affected by climate change?

• The beaches on which seabirds nest are in danger of being lost due to rising sea levels.

• Sources of food that seabirds prey on will increase as the ocean becomes warmer.

• Ocean acidification causes the eggs of seabirds to be thinner which makes them fragile and likely to crack.

• Increasing air temperatures prevents seabirds from flying and thus reaching new areas to find food.

How can climate change cause an increase in human diseases such as malaria and dengue fever?

• Melting ice releases the trapped spores that cause these diseases to spread into the atmosphere.

• These diseases are known to spread more widely with increased heat and humidity.

• The vectors that transmit these diseases are dependent upon ocean acidification to activate.

• Colder waters transmit these diseases more frequently to humans than warmer waters.

Which adaptation is working against the survival of koalas as global climate change causes Earth's temperatures to increase?

• Thick fur that keeps koalas warm.

• Lighter fur that reflects sunlight.

• Smaller body size to reduce heat absorption.

• Increased nocturnal activity to avoid daytime heat.

Which of the following human actions would help to improve the overall conditions of coral reefs?

• Eating more seafood.

• Reducing the use of lawn and garden chemicals.

• Eating less seafood by eating more red meat.

• Driving motorcycles instead of cars.

If the Greenland ice sheet melts completely due to warmer temperatures, which of the following describes the effect?

• Average global temperatures will continue to decrease rapidly.

• Carbon dioxide concentrations over Europe will increase.

• The water surrounding Greenland will become more salty.

• The city of Miami, Florida, would be underwater.

Which of the following describe how global climate change can threaten human health? Choose all that apply:

• Cases of diseases carried and transferred by mosquitoes like malaria and dengue fever will increase due to warmer temperatures and more humidity.

• Access to sources of clean drinking water will increase as water becomes warmer.

• Pollution and pollen seasons will increase leading to more cases of allergies and asthma.

• Hunger will increase due to droughts causing shortages of food and the inability to grow crops.

Which of the following statements describes the effect of increasing temperatures on the oceans?

• Salt content increases as ice caps melt.

• Tidal patterns change from 6 hours to 10 hours.

• Its overall volume increases as more water is added to the oceans from melting land ice.

• Waves become stronger due to the evaporation of water and lower sea levels.
