Preguntas del test (17)
1Why do you think we leave sedimentary rocks and limestone out of the carbon cycle simulation?(Use animation)
- Athey contain too much carbon
- Bthey have too many complex flows in and out
- Cconsidering their size, they really don't have any flows in or out.
- DThey just aren't important to the planet
2What is the largest reservoir that actually cycles some carbon?(use pie charts or animation)
- Asurface water
- Bdeep ocean water
- Cplants
- Dsoil
3How much of the deep ocean is actually cycled? (use animation)
- A100 gt
- B20000000 gt
- C37000 gt
- D570 gt
4What is the total amount of carbon that is released into the atmosphere every year? (use bar graph chart or slide 5)
- Aabout 100 gt
- Babout 150 gt
- Cabout 220 gt
- Dabout 400 gt
5How much carbon flows out of the atmosphere? (use charts or slide 6)
- Aabout 100 gt
- Babout 210 gt
- Cabout 55 gt
- Dabout 350 gt
6Which flow out of the atmosphere is the largest?(use pie charts or slide 6)
- AAtmosphere to ocean(diffusion)
- BPhotosynthesis
- CPrecipitation
- DRespiration
7Which of the following reservoirs is losing carbon to the atmosphere and not being refilled?(use animation)
- Aplants
- Bsurface ocean
- Cdeep ocean
- Dfossil fuels
8Which of the following flows into the atmosphere do not have a flow that balances it out? (use animation)
- Adiffusion
- Bphotosynthesis
- Ccombustion of fossil fuels
- Dplant respiration
9Why is there a difference between the flows into the atmosphere, and out of the atmosphere? (use charts)
- Aplants should be taking up more carbon dioxide
- Bhumans release about 5 gt of carbon to the atmosphere due to industry.
- Canimals respire too much
- Dhumans release about 10 gt of carbon to the atmosphere due to industry.
10Volcanoes 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)
- AHumans release much less carbon dioxide than volcanoes
- BHumans release about the same amount of carbon dioxide versus volcanoes
- CHumans release 2x the carbon dioxide of volcanoes
- DHumans release about 300x more carbon dioxide than volcanoes
11This reservoir makes up 80% of the carbon that moves actively through the carbon cycle?(use pie charts)
- Adeep ocean
- Bfossil fuels
- Csurface ocean
- Datmosphere
12Which of the following correctly describes how carbon moves between the ocean and atmosphere?(use animation)
- AThe ocean takes in more carbon than it releases to atmosphere due to diffusion
- BThe atmosphere takes in more carbon than it releases to the ocean diffusion
- CThey both exchange 90 gigatons of carbon per year
- Dthere is not enough information
13Which of the following flows only increases carbon dioxide concentrations in the atmosphere?(use slide 5 and 6)
- Aprecipitation
- Bphotosynthesis
- Cdiffusion
- Drespiration
14[blank_start]Coal[blank_end] is the largest fossil fuel reservoir left on the planet.
- ACoal
15Which human industry use increases carbon dioxide in the atmosphere the most?(use slide 5 or animation)
- Athe making of cement
- Bdeforestation or land use
- Ccombustion of fossil fuels
- Dvolcanoes
16Deforestation 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)
- Aburning trees is combustion and release carbon dioxide into the atmosphere
- Bfarms will absorb more carbon dioxide so it will help balance the cycle
- Cremoving trees means they can't perform photosynthesis...less trees means more carbon dioxide in the atmosphere
- Dboth A and C
17Which of the following might help rebalance the carbon cycle? ( Use brain)
- APlant more trees or stop deforestation so there is more photosynthesis
- BDecrease combustion of fossil fuels
- CIncrease photosynthetic sea life that sinks to the bottom when it dies
- DAll of the above
