Quizplus · Accepted Answer

Carbon dioxide is the most abundant form of atmospheric carbon. It makes up approximately 0.04% of the Earth's atmosphere. While other forms of carbon exist in the atmosphere, they are present in much smaller quantities. Carbon monoxide, hydrocarbons, and carbon tetrachloride are all present in the atmosphere, but at levels that are much lower than carbon dioxide. Carbonic acid is not a gas and is not present in the atmosphere as such.
