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.
The Carbon Cycle. Where is most of the Earth's carbon located and in what form? Most of the world's carbon is found in the ocean as either carbon dioxide or calcium carbonate. Shells of most sea creatures are composed of calcium carbonate. Once these creatures die their shells turn into limestone and as limestone erodes the carbon is released into the atmosphere or bodies of water.
