Definition of carbon dating for kids
Radioactive carbon (Carbon 14) is formed in the upper atmosphere as a byproduct of cosmic radiation.
Cosmic rays are positively charged atoms moving at enormous speeds.
Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.
Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.
A carbon credit, then, is essentially a permit that allows the receiver to burn a specified amount of hydrocarbon fuel over a specified period of time.
Credits are granted to companies or other groups that take action to measurably reduce carbon emissions.
The premise of the system is that a government or another body can regulate the total tons of carbon dioxide emitted but is given some flexibility as to how exactly the regulation is accomplished.
Carbon credit systems place a cost on carbon emissions by creating credits valued against one ton of hydrocarbon fuel.
Each allotrope of carbon has different physical properties.
You probably have seen or read news stories about fascinating ancient artifacts.
At an archaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.
Carbon is the fourth most abundant element in the universe by mass and the second most abundant element in the human body.
Carbon is constantly cycled through the Earth's oceans, plant life, animal life, and atmosphere. Characteristics and Properties Carbon is found on Earth in the form of three different allotropes including amorphous, graphite, and diamond.
The radioactive carbon has six protons and eight neutrons in its nucleus, giving it a total atomic mass of 14.
