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.
Carbon that is a part of rocks and fossil fuels like oil, coal, and natural gas may be held away from the rest of the carbon cycle for a long time. These long-term storage places are called âsinksâ. When fossil fuels are burned, carbon that had been underground is sent into the air as carbon dioxide, a greenhouse gas.
