How is carbon dioxide produced 2 points?
Carbon dioxide is emitted when hydrocarbon fuels (such as wood, coal, natural gas, gasoline, and oil) are burned. Carbon from fossil fuels reacts with oxygen in the air to form carbon dioxide and water vapour during combustion or burning.
Where is carbon dioxide produced?
Carbon dioxide (CO2) comes from both natural sources (including volcanoes, the breath of animals and plant decay) and human sources (primarily the burning of fossils fuels like coal, oil and natural gas to generate energy).
Where is carbon dioxide most produced?
China is, by a significant margin, Asia's and the world's largest emitter: it emits nearly 10 billion tonnes each year, more than one-quarter of global emissions. North America – dominated by the USA – is the second largest regional emitter at 18% of global emissions. It's followed closely by Europe with 17%.Oct 3, 2019
How is carbon dioxide produced?
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.Nov 8, 2016
What is the largest source of carbon dioxide in the world?
At the global scale, the key greenhouse gases emitted by human activities are: Carbon dioxide (CO2): Fossil fuel use is the primary source of CO2.Feb 25, 2022
How is carbon dioxide produced Class 7?
Carbon dioxide is emitted when hydrocarbon fuels (such as wood, coal, natural gas, gasoline, and oil) are burned. Carbon from fossil fuels reacts with oxygen in the air to form carbon dioxide and water vapour during combustion or burning.
How is carbon dioxide produced in our body for Class 7?
Cellular respiration converts ingested nutrients in the form of glucose (C6H12O6) and oxygen to energy in the form of adenosine triphosphate (ATP). CO2 is produced as a byproduct of this reaction.Jan 4, 2022
What is CO2 and how is it produced?
Carbon dioxide (CO₂) is a colourless and odourless gas that is a natural component of our air and makes up part of the carbon cycle. Through the decomposition of organic matter, CO₂ is released into the atmosphere as part of this natural process.
What is the main producer of CO2?
The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.Aug 5, 2022
