Fun facts about carbon dating
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.Allotropes are materials made from the same element, but their atoms fit together differently.Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere; the neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle: it is absorbed from the air by green plants and then passed on to animals through the food chain.Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.Once the organism dies, however, it ceases to absorb carbon-14, so that the amount of the radiocarbon in its tissues steadily decreases. This is an informational tour in which students gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.
Its trunk can hold up to 120,000 liters (32,000 US gallons) of water which is an adaptation to the harsh drought conditions of its environment. The cork-like bark is reddish brown to grey, soft and possesses longitudinal fibers.
French scientist Antoine Lavoisier determined that diamond was made of carbon in 1772. Carbon gets its name from the Latin word "carbo" meaning charcoal or coal.
Isotopes There are two stable naturally occurring isotopes of carbon, carbon-12 and carbon-13.
The bark is fire resistant and are used for making cloth and rope.
Leaves simple to digitate, with up to 9 green and glossy leaflets but usually 5.
