Sore throat is a symptom, not a disease. In each case, there was a different cause that dictated a different treatment. The scratchy throat probably was a mechanical problem caused by dry, heated winter air and aggravated by my friend's tendency to breathe through her mouth when she sleeps.
Definition. Carbon-storing natural feature (such as a forest or the land mass) that exchanges carbon with other reservoirs. A reservoir from which no outflow of carbon compounds takes place is called carbon sink.
1 This is by far the largest reservoir. 2  The carbon dioxide is stored in the interior of the Earth in the form of carbonate rocks, such as limestone, dolomites, and chalk. 3  However, carbon from this reservoir is exchanged extremely slowly with the carbon in the ocean and atmosphere.
