The carbon cycle is the exchange of carbon among three reservoirs or storage places: the land‚ the oceans‚ and the atmosphere The atmosphere has the least amount of carbon‚ followed by the land with it plants and animals‚ also

Chemistry Pg. 1 Carbon Dating Carbon dating is the most reliable‚ commonly used‚ and useful dating method‚ for what it can date. It is used to date late Pleistocene and Holocene artifacts and geologic events up to 50‚000 years decayed. Carbon dating has been very beneficial to the scientific world‚ because it is used in so many different fields of science‚ including archaeology‚ geology‚ oceanography‚ hydrology‚ atmospheric science‚ and paleoclimatology. The radiocarbon dating method was developed

Carbon steel is steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%. The American Iron and Steel Institute(AISI) defines carbon steel as the following: "Steel is considered to be carbon steel when no minimum content is specified or required for chromium‚cobalt‚ molybdenum‚ nickel‚ niobium‚ titanium‚ tungsten‚ vanadium or zirconium‚ or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0

Carbon Footprint briefly defined is the amount of CO2 left behind after any human activity. They can be classified into primary and secondary footprints. [ (McLean 2008) ] Primarily‚ it is the direct emission of CO2 from burning fossil fuels or any kind of fuels. They are considered the main and biggest source of CO2 emission‚ thus the having biggest Carbon Footprints. [ (McLean 2008) ] The CO2 emissions from all products and their life-cycles are considered as secondary footprints. The life-cycle

fuels‚ substandard emission techniques‚ and an ever growing population all play an intricate role of raising Earth’s overall temperature. Each can be linked through one key adversary‚ carbon dioxide. Rising CO2 levels are almost the sole reason temperatures are rising at such an alarming rate. Aside from water vapor‚ carbon dioxide is a chief ingredient in our Greenhouse Effect stew. It’s everywhere. It emits from our cars‚ it flies from our smokestacks‚ and it empties from our lungs. All of Earth is

"A carbon fiber is a long‚ thin strand of material about 0.005-0.010 mm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fiber. The crystal alignment makes the fiber incredibly strong for its size. Several thousand carbon fibers are twisted together to form a yarn‚ which may be used by itself or woven into a fabric. The yarn or fabric is combined with epoxy and wound or molded

Carbon Sink A carbon sink is a natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite period. The process by which carbon sinks remove carbon dioxide (CO2) from the atmosphere is known as carbon sequestration. Public awareness of the significance of CO2 sinks has grown since passage of the Kyoto Protocol‚ which promotes their use as a form of carbon offset. The main natural sinks are: Absorption of carbon dioxide by the oceans

Carbon Monoxide Carbon monoxide (CO) is a colorless‚ odorless‚ and tasteless gas that is slightly less dense than air. It is toxic to humans and animals when encountered in higher concentrations. Every year‚ at least 430 people die in the U. S. from accidental CO poisoning. It is also produced in normal animal metabolism in low quantities. In the atmosphere‚ it has a role in the formation of ground-level ozone. Carbon monoxide consists of one carbon atom and one oxygen atom‚ connected by a triple
