The amount of sunlight reflected by a surface due to its color.
Which one of the choices below is NOT a cause for global warming?
Raising huge numbers of farm animals in small spaces / CAFOs
Burning coal to generate electricity
Planting large numbers of trees
About 100,000 airplane flights a day
Riding a bicycle to school every day
Which of the following have been linked to climate change?
droughts
flooding
melting of polar ice caps
Increase in the number and severity of tropical storms/cyclones/hurricanes
all of the above
What is something that individuals could do to lessen the human impact on climate change?
Eat a vegetarian meal twice a week
Share rides in your car with 3 other co-workers (carpool)
Showering five times a day
Eating at McDonalds for dinner three times a week.
Conserving electricity by turning off lights when not in use, or switching to compact fluorescent bulbs.
Which of the following is the best conclusion that can be made from this graph?
atmospheric carbon dioxide levels have been decreasing since 1960
Hawaii has a lot of carbon dioxide
humans have been working hard to decrease carbon dioxide levels
atmospheric carbon dioxide levels have increased steadily since 1960
The greenhouse effect is beneficial as it helps to sustain life on earth by naturally trapping heat in the atmosphere.
False
True
What are greenhouse gases?
gases that keep energy from sunlight from escaping to space, thus making Earth warmer
gases that emit green smoke
gases that are used to make green colored glass
gases that are used to power transportation
The most common fuel source used to generate electricity worldwide is?
wood
natural gas
oil
coal
peat
Scientists predict that the hurricanes coming off the warming waters of the Gulf of Mexico will be less severe and less frequent.
True
False
Which of the following gases DOES NOT trap heat?
carbon dioxide
nitrogen
water vapor
methane
chlorofluorocarbons-cfcs
Over the past 200 years, the level of carbon dioxide in the atmosphere has
decreased slightly
increased until recently, and then decreased
increased steadily
stayed about the same
What does the term "anthropogenic" mean?
something that is NOT caused by human activity
a naturally occurring cause
originating from human activity
something that everyone should care about
Which of the following is the largest carbon sink ? (Note: this list does not include sedimentary rock -the largest of all)
The Amazon
The Oceans
The Deserts
The Forests
About 97% of the water on Earth is ...
fresh water
groundwater
salt water
ice
residential water
How does eutrophication affect other organisms in the aquatic environment?
Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.
The water becomes better able to support aerobic organisms.
The algae provide food for fishes and other organisms, leading to decreased algae populations.
The extra nitrogen provides additional food for the other organisms, increasing their population.
Why does the annual cycle of CO2 fluctuate up and down?
Because of uncertainties in the data collection
Because of the tilt of the Earth's axis.
Due to annual change in deciduous vegetation, new leaves in spring-summer and decaying leaves during fall-winter.
Because people use more electricity during winter.
What do you call a forest, ocean or natural environment that can absorb and hold large amounts of CO2 from the atmosphere?
Biomes
Albedo
Biodiversity
Carbon Sink
The total variety of different organisms that live in an environment.
Carbon cycle
Biodiversity
Water cycle
carbon sink
What does B.O.D. stand for?
Biochemical Oxygen Demand
Bowel Odor Demonstration
Big Old Dufus
Buy Only Dolce & Gabbana
What can we infer from this pop. pyramid?
Many people grow old in Somalia.
Somalia is rich and prospering.
Somalia has a growing population.
Somalia has low infant mortality.
Somalia has high child mortality.
