How does deforestation contribute to the rise in carbon dioxide levels in the atmosphere?

Deforestation contributes to the rise in carbon dioxide levels in the atmosphere because trees absorb carbon dioxide during photosynthesis. When trees are cut down or burned, the stored carbon is released back into the atmosphere, increasing the overall amount of carbon dioxide present. This leads to higher levels of carbon dioxide in the atmosphere, which contributes to global warming and climate change.


What process of the carbon cycle is likely causing the increase in carbon dioxide levels in carbon dioxide levels?

The increase in carbon dioxide levels is primarily caused by the process of combustion, where fossil fuels such as coal, oil, and natural gas are burned for energy. This releases stored carbon into the atmosphere in the form of CO2. Additionally, deforestation contributes to rising CO2 levels by reducing the number of trees that can absorb carbon dioxide through photosynthesis. These human activities significantly enhance the natural carbon cycle, leading to higher atmospheric carbon dioxide concentrations.


How is carbon dioxide levels replenished?

Carbon dioxide levels are replenished through natural processes such as respiration by living organisms and volcanic eruptions. Additionally, activities like burning fossil fuels and deforestation release carbon dioxide into the atmosphere, adding to the overall levels.


What happened to the levels of oxygen and carbon dioxide?

Oxygen levels decreased while carbon dioxide levels increased due to human activities such as deforestation, burning of fossil fuels, and industrial activities. This has led to climate change and impacts on ecosystems.


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.


What has caused Carbon Dioxide levels to steadily increase since the 1800s?

The burning of fossil fuels (coal & oil) is the primary cause of the increase in carbon dioxide levels in the atmosphere.


What reasons are there for the recent changes in atmospheric carbon dioxide levels?

Well, there are Changes caused by People and by other causes; mostly by People burning fossil fuels (coal, oil and natural gas), and by Deforestation.


Which human activity might explain the change in carbon dioxide levels?

Our dependence on fossil fuels for electricity and transport is the main reason for the recent change in carbon dioxide levels. Also deforestation. Humans have cut down great forests all over the world.


Does carbon dioxide rise or fall in the atmosphere over time?

Carbon dioxide levels in the atmosphere have been rising over time due to human activities such as burning fossil fuels and deforestation.


Which is not a major source of carbon dioxide?

One major source of carbon dioxide is not deforestation, although it contributes to increased CO2 levels by reducing the number of trees that can absorb it. Instead, the primary sources of carbon dioxide emissions include burning fossil fuels for energy, industrial processes, and transportation. Deforestation is more of an indirect source, as it exacerbates the problem by limiting carbon uptake.


What effect does deforestation have on the levels of carbon dioxide oxygen and water vapor in the atmosphere?

Deforestation significantly increases carbon dioxide levels in the atmosphere, as trees, which absorb CO2 during photosynthesis, are removed. This loss of vegetation also reduces oxygen production, leading to lower oxygen levels. Additionally, deforestation disrupts local water cycles by decreasing transpiration, which can result in reduced humidity and altered precipitation patterns, ultimately affecting water vapor levels 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.
