as a gas.....
Carbon Dioxide (CO2) from the air.
As fossil fuels are made up of Carbon and Hydrogen. This burns in oxygen (in air) to form Carbon dioxide and Water, so the carbon dioxide is released into the air
the cold air can change the carbon dioxide gas to a solid
Carbon dioxide dissolved in water form carbonic acid.
It gets the Carbon Dioxide form the air. It has holes in its leaves to set the air in called 'stomata'.
Carbon most commonly enters the air as a gas: carbon dioxide, volatile organic compounds, or carbon monoxide, but it can also exist in the air as a solid (soot) for long periods of time. Carbon is an element in a solid form. When it released in air, it remains in the same form. If it is burnt in air then it released carbon dioxide & carbon mono oxide.
Gas burns in the air to form carbon dioxide (CO2) and water (H2O).
There is no carbon in air but in the atmosphere there is 387 PPMV (parts per million by volume) present in the form of CO2 carbon dioxide.
Rocks typically react with carbon dioxide in the air to form carbonic acid, which contributes to weathering and erosion processes.
As fossil fuels are made up of Carbon and Hydrogen. This burns in oxygen (in air) to form Carbon dioxide and Water, so the carbon dioxide is released into the air
Carbon in the form of charcoal or graphite reacts with oxygen in the air to produce carbon dioxide when it burns.
When ethane burns in the air, it reacts with oxygen to form carbon dioxide and water. This process releases energy in the form of heat and light.
