Transcript of Carbon Cycle
What is the carbon cycle...
The carbon cycle is how carbon in all of its various forms moves between plants, animals, the oceans, and the atmosphere. Carbon is everywhere.
Long Term Carbon Sink
Short Term Carbon Sink
What is a short term carbon sink?
Short term carbon sink is a natural environment that traps carbon for a short term.
- Dead Organisms (plants and animals)
- Cow's fart
- Shell forming animals lock away CO2 in their shells
How is carbon removed from the atmosphere.
Photosynthesis- The process plants go to create there food. Carbon is removed because of the photosynthesis using co2
Creation of limestone. Limestone uses calcium carbonate which uses carbon
Acid rain (CO2+H2O=H2CO3) Again C02 is being used.

What is a Long term Carbon Sink?
A long term carbon sink is basically anything that stays for a long time even if it maybe forever which observes more carbon than it releases.
- Deep ocean (evaporation)
- Fossil fuel (volcano combustion)
How Carbon is added to the atmosphere
The Carbon starts in the atmosphere. Then it finds its way in a plant. This is called a photosynthesis.
Then the atom will transfer into a animal organism because at some time the animal will eat the plant.
Then the animal releases carbon as it respires.
Soon the animal will die and decompose. From there the atom goes back up in the atmosphere because of combustion.
Photosynthesis is the process of plants making their food.
Respiration is basically the action of breathing.
Carbonate rock formation
Carbonate rocks are a class of sedimentary rocks composed primarily of carbonate minerals
Animals and plants respiring
Rise of temperature on water
(because of evaporation)
Three ways human alter the carbon cycle
- Burning fossil fuels
Where is there less carbon and where is there more carbon due to human involvement?
Human activities are affecting the carbon cycle in many ways. The burning of the fossil fuels and deforestation release carbon dioxide into the atmosphere.
The government releases a policy that each company can only take a certain amount of carbon which is less amount than is being released now and if this amount is exceeded then there will be a large fine.
- I should start using more of the public bus and less of car and taxi.
- Make sure that all my lights and air conditioner off.
- Try to reduce the water use while in the shower
How we can make a difference
We already have the technology to capture the CO2 released and prevent it from going into the atmosphere. What we need is the technology to store these CO2 which has a long storage time and is cheap
