Question
Which of the following is TRUE about CO2 in the atmosphere?a.A large percentage of CO2 in the atmosphere comes from natural carbon cycleb.Deforestation leads to more CO2 in the atmospherec.CO2 can only come from natural sourcesd.CO2 in the atmosphere only comes from anthropogenic sources
Solution
The correct answer is:
a. A large percentage of CO2 in the atmosphere comes from the natural carbon cycle - This is TRUE. The natural carbon cycle does contribute a large amount of CO2 to the atmosphere. This includes processes such as respiration, decay of organic material, and volcanic eruptions.
b. Deforestation leads to more CO2 in the atmosphere - This is TRUE. When trees are cut down, they can no longer absorb CO2 from the atmosphere. Additionally, if the wood is burned or decays, it releases the CO2 it had previously stored back into the atmosphere.
c. CO2 can only come from natural sources - This is FALSE. CO2 can also come from anthropogenic (human-caused) sources, such as burning fossil fuels (coal, oil, and natural gas) and deforestation.
d. CO2 in the atmosphere only comes from anthropogenic sources - This is FALSE. As mentioned above, CO2 in the atmosphere can come from both natural and anthropogenic sources.
