Burning forests release carbon dioxide, which reduces the amount of oxygen produced during photosynthesis. This can lead to a decrease in oxygen levels in the immediate area, particularly if the burning is extensive and long-lasting. However, the overall impact on global oxygen levels is minimal due to the Earth's large oxygen reserves.
What else can I help you with?
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.
Does forest area have more oxygen?
Forests do produce oxygen as a byproduct of photosynthesis, but they do not significantly increase the overall oxygen levels in the atmosphere. The main source of oxygen on Earth is the oceans, not forests. Forests are crucial for biodiversity, carbon sequestration, and climate regulation.
How do the oxygen (O2) and carbon dioxide (CO2) levels change over time?
Oxygen levels decrease and carbon dioxide levels increase over time due to activities like respiration, photosynthesis, and human activities like burning fossil fuels. This can lead to imbalances in the atmosphere affecting ecosystems and climate.
How do the oxygen and carbon dioxide levels change over time?
Oxygen levels tend to remain relatively stable over time due to the balance between oxygen production from photosynthesis and oxygen consumption by organisms. Carbon dioxide levels, on the other hand, can fluctuate due to human activities such as burning fossil fuels and deforestation, leading to an overall increase in atmospheric CO2 concentrations over time.
How does burning affect oxygen cycle?
When burning occurs, especially of organic materials like trees or fossil fuels, it releases carbon dioxide into the atmosphere. This can lead to an increase in carbon dioxide levels, which can affect the balance of gases in the atmosphere and impact the oxygen cycle. Increased carbon dioxide levels can also contribute to global warming and climate change, which can further disrupt the oxygen cycle.
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.
Is burning of sulphur with oxygen a physical or chemical change?
Burning sulfur, or burning anything, is a chemical change.
Does forest area have more oxygen?
Forests do produce oxygen as a byproduct of photosynthesis, but they do not significantly increase the overall oxygen levels in the atmosphere. The main source of oxygen on Earth is the oceans, not forests. Forests are crucial for biodiversity, carbon sequestration, and climate regulation.
How would the burning of forests affect your oxygen?
In the process of photosynthesis vegetation absorb carbon dioxide and release oxygen; less forests, more pollution, more green house effect, more acidic seas, less oxygen for us.
Why is a burning candel a chemical change and not a physical changes?
Burning is a chemical reaction with oxygen (oxidation).
How do the oxygen (O2) and carbon dioxide (CO2) levels change over time?
Oxygen levels decrease and carbon dioxide levels increase over time due to activities like respiration, photosynthesis, and human activities like burning fossil fuels. This can lead to imbalances in the atmosphere affecting ecosystems and climate.
How do the oxygen and carbon dioxide levels change over time?

Carbon dioxide levels, on the other hand, can fluctuate due to human activities such as burning fossil fuels and deforestation, leading to an overall increase in atmospheric CO2 concentrations over time.
Why is anything burning a chemical change?
Burning is oxidation, which means that the compounds in whatever is burning are being chemically combined with oxygen.
Is burns in the presence of oxygen physical or chemical change?
The process of burning in the presence of oxygen is that of a chemical change. It is a chemical change and not a physical change because the prodects do not have the same properties as the reactants.
How does burning affect oxygen cycle?
When burning occurs, especially of organic materials like trees or fossil fuels, it releases carbon dioxide into the atmosphere. This can lead to an increase in carbon dioxide levels, which can affect the balance of gases in the atmosphere and impact the oxygen cycle. Increased carbon dioxide levels can also contribute to global warming and climate change, which can further disrupt the oxygen cycle.
When magnesium is burning in the presence of oxygen what are some evidence that a chemical change is occurring?
Some evidence that a chemical change is occurring when magnesium is burning in the presence of oxygen include the formation of a white powdery substance (magnesium oxide), the emission of light and heat, and the change in physical properties of the magnesium (e.g., color change or formation of ash).
What would happen if the vast areas of forests are cleared?
Oxygen levels will decrease and species of animals will gradually disappear.
