What is a geological reservoir of CO2?
Volcanoes or geysers
100
Process that plants utilize to make food and oxygen from CO2 and light
Photosynthesis-- Makes plants a carbon reservoir because they take in carbon from the atmosphere
100
What processes in the human/animal bodies produce CO2?
100
In what process does CO2 move from the atmosphere to the ocean?
100
What era in human history marked the beginning of increased CO2 emissions?
Ever since the Industrial Revolution.

What are the two reservoirs involved in ocean acidification (due to absorption of CO2)?
Ocean and Atmosphere

What is the main source of CO2 releasing processes from humans?
Transportation and combustion of fossil fuels.

How does carbon get released from ALL biomass to the atmosphere and/or geological formations?
Decomposition releases carbon into the air which can also get trapped in geological formations (this relates to carbon dating)!
200
Which celebrity single handedly brings the world closer to global warming?
Taylor Swift, with her annual carbon emissions 1000x larger than the average person.
300
What part of the geosphere is a significant reservoir for carbon?
The crust. This is where fossil fuels and carbon containing sediments like limestone are located.
300
Percentage of CO2 per year do plants absorb?
30%
300
How does deforestation impact the carbon cycle?
Trees serve as carbon sinks, so when there are less trees there are less sinks—as a result, more carbon is found in the atmosphere.

300
Describe the correlation of limestone with CO2 processes
Limestone is formed due to the CO2 process of compaction where carbon found in water sources becomes limestone sediment
300
Are electric cars better for the environment than gas combustion cars?
Not necessarily better for the environment because of the battery manufacturing processes, but much less CO2 emissions compared to gas cars.
400
What is the world's largest natural carbon sink?
The Congo Basin is the largest carbon sink in the world, absorbing more carbon than the Amazon.

400
Name 2 other biotic reservoirs for carbon that do not use photosynthesis
Prokaryotes (including bacteria) and Animals
400
How much of the world relies on fossil fuels?
80%
400
Largest naturally occurring CO2 releasing process (moves from the ocean to the atmosphere)?
Outgassing from the ocean. This occurs in warmer bodies of water and refers to removal of gas from the ocean due to higher metabolic activity.
400
What is the country with the largest CO2 emissions?
China, with 3x as much emissions as the second most CO2 emitting country (United States)
500
Ferb tells Phineas the percent of the atmosphere's CO2 absorbed by the ocean per year is 45%, evaluate the accuracy of this statement
False; The percentage of atmospheric CO2 absorbed by the ocean is 30%
500
What biome absorbs the largest amount of CO2 annually?
Rainforests (in general due to their large biomass)
500
What percentage of energy can renewable energy compensate for the energy fossil fuel produces?
Renewable energy and electrification alone can deliver 75% of energy-related CO2 emissions.
500
The burning of wildfires releases CO2– how many metric tonnes have they released since 2022?
5.3 billion metric tonnes
500
What is the most effective strategy to prevent CO2 pollution other than renewable energy?
Stop overpopulation
