question 54

Multiple Choice

The Keeling graph of Carbon Dioxide concentrations form a pattern that goes up and down each year. What is the cause of this oscillating pattern?

• A) More combustion of wood and fossil fuels occur in the winter than the summer contributing to the increased CO₂.
• B) In the summer of Hawaii, much of the snow melt on Mauna Loa and CO₂ is released.
• C) During the northern hemisphere summer, there are so many trees, that they reduce the amount of CO₂ substantially, but when northern winter occurs, there are not enough trees in the southern hemisphere to use all of the inputs of CO₂ in the atmosphere.
• D) During the southern hemisphere summer, there are so many trees, that they reduce the amount of CO₂ substantially, but when southern winter occurs, there are not enough trees in the northern hemisphere to use all of the inputs of CO₂ in the atmosphere.
