Calculating the Carbon Cycle

Calculating the Carbon Cycle

Question 1 of 17

1

Why do you think we leave sedimentary rocks and limestone out of the carbon cycle simulation?(Use animation)

Select one of the following:

  • 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

Explanation

Question 2 of 17

1

What is the largest reservoir that actually cycles some carbon?(use pie charts or animation)

Select one of the following:

  • surface water

  • deep ocean water

  • plants

  • soil

Explanation

Question 3 of 17

1

How much of the deep ocean is actually cycled? (use animation)

Select one of the following:

  • 100 gt

  • 20000000 gt

  • 37000 gt

  • 570 gt

Explanation

Question 4 of 17

1

What is the total amount of carbon that is released into the atmosphere every year? (use bar graph chart or slide 5)

Select one of the following:

  • about 100 gt

  • about 150 gt

  • about 220 gt

  • about 400 gt

Explanation

Question 5 of 17

1

How much carbon flows out of the atmosphere? (use charts or slide 6)

Select one of the following:

  • about 100 gt

  • about 210 gt

  • about 55 gt

  • about 350 gt

Explanation

Question 6 of 17

1

Which flow out of the atmosphere is the largest?(use pie charts or slide 6)

Select one of the following:

  • Atmosphere to ocean(diffusion)

  • Photosynthesis

  • Precipitation

  • Respiration

Explanation

Question 7 of 17

1

Which of the following reservoirs is losing carbon to the atmosphere and not being refilled?(use animation)

Select one of the following:

  • plants

  • surface ocean

  • deep ocean

  • fossil fuels

Explanation

Question 8 of 17

1

Which of the following flows into the atmosphere do not have a flow that balances it out? (use animation)

Select one of the following:

  • diffusion

  • photosynthesis

  • combustion of fossil fuels

  • plant respiration

Explanation

Question 9 of 17

1

Why is there a difference between the flows into the atmosphere, and out of the atmosphere? (use charts)

Select one of the following:

  • 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.

Explanation

Question 10 of 17

1

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)

Select one of the following:

  • 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

Explanation

Question 11 of 17

1

This reservoir makes up 80% of the carbon that moves actively through the carbon cycle?(use pie charts)

Select one of the following:

  • deep ocean

  • fossil fuels

  • surface ocean

  • atmosphere

Explanation

Question 12 of 17

1

Which of the following correctly describes how carbon moves between the ocean and atmosphere?(use animation)

Select one of the following:

  • 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

Explanation

Question 13 of 17

1

Which of the following flows only increases carbon dioxide concentrations in the atmosphere?(use slide 5 and 6)

Select one of the following:

  • precipitation

  • photosynthesis

  • diffusion

  • respiration

Explanation

Question 14 of 17

1

Fill the blank space to complete the text.

is the largest fossil fuel reservoir left on the planet.

Explanation

Question 15 of 17

1

Which human industry use increases carbon dioxide in the atmosphere the most?(use slide 5 or animation)

Select one of the following:

  • the making of cement

  • deforestation or land use

  • combustion of fossil fuels

  • volcanoes

Explanation

Question 16 of 17

1

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)

Select one of the following:

  • 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

Explanation

Question 17 of 17

1

Which of the following might help rebalance the carbon cycle? ( Use brain)

Select one of the following:

  • 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
