Why do you think we leave sedimentary rocks and limestone out of the carbon cycle simulation?(Use animation)
they contain too much carbon
they have too many complex flows in and out
considering their size, they really don't have any flows in or out.
They just aren't important to the planet
What is the largest reservoir that actually cycles some carbon?(use pie charts or animation)
surface water
deep ocean water
plants
soil
How much of the deep ocean is actually cycled? (use animation)
100 gt
20000000 gt
37000 gt
570 gt
What is the total amount of carbon that is released into the atmosphere every year? (use bar graph chart or slide 5)
about 100 gt
about 150 gt
about 220 gt
about 400 gt
How much carbon flows out of the atmosphere? (use charts or slide 6)
about 210 gt
about 55 gt
about 350 gt
Which flow out of the atmosphere is the largest?(use pie charts or slide 6)
Atmosphere to ocean(diffusion)
Photosynthesis
Precipitation
Respiration
Which of the following reservoirs is losing carbon to the atmosphere and not being refilled?(use animation)
surface ocean
deep ocean
fossil fuels
Which of the following flows into the atmosphere do not have a flow that balances it out? (use animation)
diffusion
photosynthesis
combustion of fossil fuels
plant respiration
Why is there a difference between the flows into the atmosphere, and out of the atmosphere? (use charts)
plants should be taking up more carbon dioxide
humans release about 5 gt of carbon to the atmosphere due to industry.
animals respire too much
humans release about 10 gt of carbon to the atmosphere due to industry.
Volcanoes are known as a destructive force because they can release tons of carbon dioxide every year? How does human releases compare to volcanoes?(use slide 5 or pie charts)
Humans release much less carbon dioxide than volcanoes
Humans release about the same amount of carbon dioxide versus volcanoes
Humans release 2x the carbon dioxide of volcanoes
Humans release about 300x more carbon dioxide than volcanoes
This reservoir makes up 80% of the carbon that moves actively through the carbon cycle?(use pie charts)
atmosphere
Which of the following correctly describes how carbon moves between the ocean and atmosphere?(use animation)
The ocean takes in more carbon than it releases to atmosphere due to diffusion
The atmosphere takes in more carbon than it releases to the ocean diffusion
They both exchange 90 gigatons of carbon per year
there is not enough information
Which of the following flows only increases carbon dioxide concentrations in the atmosphere?(use slide 5 and 6)
precipitation
respiration
is the largest fossil fuel reservoir left on the planet.
Which human industry use increases carbon dioxide in the atmosphere the most?(use slide 5 or animation)
the making of cement
deforestation or land use
volcanoes
Deforestation is a very common practice in the Amazon rainforest where millions of acres of trees are burned in order to clear space for farms. How might this affect the carbon cycle? (Use brain and animation)
burning trees is combustion and release carbon dioxide into the atmosphere
farms will absorb more carbon dioxide so it will help balance the cycle
removing trees means they can't perform photosynthesis...less trees means more carbon dioxide in the atmosphere
both A and C
Which of the following might help rebalance the carbon cycle? ( Use brain)
Plant more trees or stop deforestation so there is more photosynthesis
Decrease combustion of fossil fuels
Increase photosynthetic sea life that sinks to the bottom when it dies
All of the above
