Carbon Cycle - Task card 10

..The carbon cycle..
1.
All living things are made up of carbon, it is part of the ocean, air, animals, humans and surprisingly even rocks. Because the Earth is a dynamic place, carbon does not stay still. It is always on the move!
- The full name for Carbon is Carbon Dioxide. -
The carbon dioxide molecule consists of one Carbon atom and two oxygen atoms.
The carbon cycle is the name given to the system in which carbon fits into our world. Basically, Plants use carbon and sunlight to make their own food to grow, The carbon becomes part of the plant. This is why tree's are important in our world because they are practically carbon eaters and oxygen distrabuters. However, when plants die and are decomposed, the carbon that was once trapped in the tree, is let out again and goes back into the earth. When deforostation takes place, a large amount of Carbon is released into the environment all at once which is bad because there is now more carbon and less oxygen being produced. When trees fall and get buried under the ground they slowly turn into fossil fuels made up of carbon like coal and oil, this process happens over millions of years. When humans burn fossil fuels, most of the carbon that has been buried under the ground for millions of years quickly enters the atmosphere as carbon dioxide. (and thats just the cycle for plants and trees)
Every living and non living thing in our world is or produces carbon.........(((will finish next lesson!!!)))
