In what ways have human activities contributed to the increase in atmospheric carbon dioxide levels?
Human activities have increased atmospheric carbon dioxide levels primarily through the burning of fossil fuels for energy, deforestation, and industrial processes.
Why are atmospheric carbon dioxide levels increasing while total carbon levels remain constant?
Atmospheric carbon dioxide levels are increasing because human activities, such as burning fossil fuels, release more carbon dioxide into the atmosphere than natural processes can remove. This imbalance leads to a buildup of carbon dioxide in the atmosphere, even though the total amount of carbon on Earth remains relatively constant.
Why are atmospheric carbon dioxide levels significantly lower in summer than in winter in a deciduous forest?
During the summer, deciduous trees undergo photosynthesis where they take in carbon dioxide to produce energy. This process helps to lower the atmospheric carbon dioxide levels. In winter, when the trees are dormant and not actively photosynthesizing, there is less carbon dioxide being absorbed, leading to higher levels in the atmosphere.
What describes seasonal changes in the levels of carbon dixode in the atmosphere?
Seasonal changes in carbon dioxide levels are driven by the Earth's natural processes. During the winter, plants go dormant and release less oxygen during photosynthesis, causing carbon dioxide levels to rise. In the spring and summer, plants become active and absorb more carbon dioxide, leading to a decrease in atmospheric levels.
What was the Carbon dioxide level in 1993?
Carbon dioxide levels in the atmosphere in 1993 were around 360 ppm (parts per million). Levels now (2013) are approaching 400 ppm.
Does cyanobacteria increase the levels of carbon dioxide in the atmosphere?
Yes, cyanobacteria can increase the levels of carbon dioxide in the atmosphere through the process of respiration. However, cyanobacteria also play a significant role in reducing atmospheric carbon dioxide levels through photosynthesis, where they convert carbon dioxide into organic compounds. Overall, the impact of cyanobacteria on atmospheric carbon dioxide levels depends on the balance between these two processes.
What is an increase in the atmospheric levels of carbon dioxide is the biggest contributor?
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to global warming.
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to What?
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to global warming.
What happens when carbon dioxide levels decrease in the atmosphere?
When carbon dioxide levels decrease in the atmosphere, it can lead to a cooling effect. This is because carbon dioxide is a greenhouse gas that traps heat in the atmosphere. A decrease in carbon dioxide levels could potentially impact climate patterns, biodiversity, and ocean acidity.
What is the increase of carbon dioxide in the atmosphere the biggest contributor to?
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to global warming.
In what ways have human activities contributed to the increase in atmospheric carbon dioxide levels?

This imbalance leads to a buildup of carbon dioxide in the atmosphere, even though the total amount of carbon on Earth remains relatively constant.
What effect does increase have on atmospheric levels of carbon?
An increased level of atmospheric carbon can have a massive impact on photosynthesis. It can boost photosynthesis in plants for example.
Would increases in atmospheric levels of carbon dioxide cause the atmosphere to become warmer?
Yes.
What aspects of urban development does NOT contribute to greater levels of atmospheric carbon dioxide?
The Use of cement
What keeps atmospheric oxygen and carbon dioxide at stable levels?
The balance of atmospheric oxygen and carbon dioxide is maintained through a combination of natural processes such as photosynthesis, respiration, and the carbon cycle. Photosynthetic organisms like plants and phytoplankton consume carbon dioxide and release oxygen, while respiration by living organisms and decomposition releases carbon dioxide back into the atmosphere. These processes work together to regulate the levels of oxygen and carbon dioxide in the atmosphere.
What keeps atmospheric oxygen and carbon dioxide at stable leves?
The balance of atmospheric oxygen and carbon dioxide levels is maintained through natural processes like photosynthesis by plants, which consumes carbon dioxide and produces oxygen, and respiration by animals, which consumes oxygen and produces carbon dioxide. Additionally, the oceans play a role in regulating carbon dioxide levels through absorption and release processes. Human activities such as burning fossil fuels and deforestation can disrupt this balance and lead to changes in these levels.
