What are two non-human activities by which carbon can enter the atmosphere as CO2 during the carbon cycle?
Volcanic eruption and animal respiration.
How is carbon reintroduced into the atmosphere?
It's part of the Carbon Cycle. By humans breathing in oxygen, your body stores complex carbohydrates internelly as a source of energy before converting the carbon back to Co2, via aerobic respiration.
What are four examples of bio geochemical cycles?
1. Biological Processes2. Geological Processes3. Chemical and Physical Processes4. Human ActivityThe biological processes like respiration, the geological processes like volcanic eruptions. Also there are the chemical/physical processes like rain, and lastly the human processes like the burning of fossil fuels.
What is one human activity that is thought to be a major contributor to global warming?
Burning of fossil fuels which releases long held carbon dioxide into the greenhouse gases in the atmosphere.Deforestation: cutting down forests all over the world that used to hold vast amounts of carbon within their wood.
How does muscular activity affect the amount of carbon dioxide produced by a human?
More Exercise=More demand for energy More demand for energy=More Respiration More respiration=More CO2
What human activities affect the carbon cycle positively and negatively?
The carbon cycle is the natural movement of carbon throughout the biosphere. There is no positive way that human activity affects it.Negative effects of human activity on the carbon cycle:Deforestation and combustion of fossil fuels are overloading the carbon cycle. By cutting down the forests we no longer have trees to remove the carbon from the atmosphere. By burning coal, oil and natural gas we are releasing age-old carbon from millions of years ago into the atmosphere.
At what point does human activity affect the natural cabon cycle?
Human Activities affect the carbon cycle at a huge rate. Release of toxins and other waste might alter the cycle.
Which human activity would have the most direct impact on the carbon cycle?
There are a few human activities that would have a direct impact on the oxygen-carbon dioxide cycle. Planting trees and other plants is one of these activities.
What are some reasons why the carbon cycle become unbalanced in the last milloin years?
Because how human activity
Does human activity have little or no impact on cycles?
No.Human activity (burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity) is having a serious effect on the carbon cycle, by adding extra carbon dioxide to the atmosphere.Human activity (pollution, overuse) is having a serious effect on the water cycle and the amount of fresh water available to our communities.
What is oxygen carbon dioxide cycle?
Oxygen-Carbon Dioxide Cycle- a continuous exchange of oxygen and carbon dioxide by plants and animals including human
What is carbon dioxide-oxygen cycle?
Oxygen-Carbon Dioxide Cycle- a continuous exchange of oxygen and carbon dioxide by plants and animals including human
How is carbon exchanged between humans and plants?
carbon is released by the human which is enhaled by the human n there fore the cycle moves on
What would happen to the temperature of the atmosphere if carbon dioxide increased due to human activity?
It will rise. The temperature of the atmosphere is rising already because carbon dioxide is increasing due to human activity.
What would happen to the temperature of the atmosphere if carbon dioxide increase due to human activity?
It will rise. The temperature of the atmosphere is rising already because carbon dioxide is increasing due to human activity.
What role do volcanoes play in emitting carbon dioxide?
They are part of the carbon cycle, and certainly are extremely important over the longest time scales. But in recent geological history volcanic activity has been very quiet, emitting an average of 0.25 gigatons annually (compared to about 35 gigatons emitted by human activity).
Humans breathing is a factor that causes an imbalance in the carbon cycle?
No, this is not true. Human breathing is part of the carbon cycle. We breathe it in, (and we take it in by eating and drinking) and we breathe it out.
