The Carbon Cycle
Transcript of The Carbon Cycle
Carbon Fun Facts
Carbon is one of the most important elements to life on Earth
Humans are about 18% carbon
The word carbon comes from the Latin word carbo, meaning coal
Carbon has the highest melting point of all elements, around 3500 °C
Carbon is a nonmetal that can bond with itself and many other chemical elements, forming nearly ten million compounds.
Carbon is made in the interiors of stars, though it was not produced in the Big Bang.
The origin of the name 'carbon' comes from the Latin word carbo, for charcoal.
•Carbon is the basic component of all living organisms.
•Carbon can travel through the land, oceans and the atmosphere.
•Carbon does this over both the short and long term.
•A long term cycle is called geological carbon cycle.
•A short term cycle is called a biological/physical cycle.
•Human have been burning carbon-containing fuels like coal and oil (called fossil fuels) for artificial power since we first harnessed steam to power their engines.
•Over the last 150 years, the burning of coal, oil, and natural gas has released around 270 billion tons of carbon dioxide into the air.
•More than half of this carbon dioxide is absorbed by the oceans, by plants, and by soils.
•Many scientists believe that carbon dioxide is a "greenhouse gas."
•Greenhouse gases trap heat and prevent it from escaping the Earth.
•This trapped gas leads to global warming, a natural phenomenon known as the greenhouse effect
•The enhanced greenhouse effects can have a disastrous effect on Earth's environment.
