Carbon Cycle Prezi
Transcript of Carbon Cycle Prezi
•Chemically transformed like nitrogen to ammonia in the nitrogen cycle
•Physically transformed like water vapor into liquid water (condensation) in the water cycle
•e.g. when clouds, which are produced in one geographic location, release the liquid water as precipitation in another geographic location. The most common form of carbon gas
is carbon dioxide. Below are some ways that are used to represent carbon dioxide. Natural Gas Coal Oil This lab is about the Carbon Cycle which is one of several matter cycles (water, oxygen, nitrogen are others)...
• The substance at the center of each cycle can be found in different forms (e.g., water vapor, water, and ice; nitrogen, ammonia, and urea)
• The substance is changed (transformed) from one form to another as it moves through the cycle (e.g., nitrogen is changed to nitrates by nitrogen-fixing bacteria)
• The substance is transported from one part of the Earth's environment to another (e.g., nitrogen moves from the air to the soil) Any cycle is made up of a complex set of interrelated processes...
•Something that affects one process within the web of a particular matter cycle will in turn affect other processes within the cycle
•Things that humans might put into the environment can affect the delicate equilibrium of these cycles
e.g. the effect of antibiotics in the nitrogen cycle in the picture that follows Source: http://toxics.usgs.gov/highlights/antibiotics_gw/ Source: http://eduspace.free.fr/ibbiology2007_14/13_opF_microbiol/nitrogen_cycle.htm 1. In the video they talk about carbon gas; what do you think they mean by this?
2. What is the difference between "young 'fast' carbon" and "old 'slow' carbon"?
3. What is important about this difference? Source: http://www.windows2universe.org/ One last bit of information before we start to focus on the Carbon Cycle...
1. Sources => These are parts of the environment that can release matter in a cycle in one of its forms.
e.g. the fossil fuels (natural gas, petroleum, and coal) in the movie you are about to watch.
2. Sinks => These are parts of the environments that can absorb matter in a cycle in one of its forms.
e.g. the plants that absorb carbon dioxide to form the fossil fuels in the movie you are about watch.
Think of an analogy: A job is a source of your money and tuition is a sink for your money. What is the carbon crisis that was mentioned in the video you watched? Watch this video
