Quizlet is a great flashcard site that helps you create your own flashcards, and provides you with some great ready-made flashcards as well. As an ESL teacher, I find it to be very useful, especially for students who are not native speakers and do not have anybody at home to help them with their vocabulary.
The atmosphere, the ocean, and the terrestrial biosphere. Carbon can be found in the earths oceanic and continental crust in different types of stones as well as in the soil from the decay of organic matter.
A carbon sink is anything that absorbs more carbon that it releases, whilst a carbon source is anything that releases more carbon than is absorb.Forests, soils, oceans and the atmosphere all store carbon and this carbon moves between them in a continuous cycle.This constant movement of carbon means that forests act as sources or sinks at different times. Not all stores of carbon are naturally cursed with such fluctuations however.In the context of climate change, the most important carbon stores are fossil fuel deposits as they have the unique benefit of being buried deep inside the earth, naturally separated from the carbon cycling in the atmosphere.ecause of this increase in atmospheric carbon, a lot of emphasis and hope has been put into the ability of trees, other plants and the soil to temporarily sink the carbon that fossil fuel burning releases into the atmosphere.
