Detailed explanation-1: -During combustion or burning, carbon from fossil fuels combine with oxygen in the air to form carbon dioxide and water vapor. These natural hydrocarbon fuels come from once-living organisms and are made from carbon and hydrogen, which release carbon dioxide and water when they burn.

Detailed explanation-2: -Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.

Detailed explanation-3: -Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat.

Detailed explanation-4: -1 Carbon dioxide and water vapour. The combustion of hydrocarbon fuels yields Carbon Dioxide (CO2) from the combustion of the carbon and Water Vapour (H2O) from the Hydrogen content.

Detailed explanation-5: -Over the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.
