What is the major driving force of the oxygen cycle?
the main two processes are plant photosynthesis, which takes carbon dioxide out of the air, and plant and animal respiration which put carbon dioxide back into the air.
How did oxygen come into the atmosphere according to evolutionists?
Scientists agree that significant amounts of oxygen were first put into the atmosphere by cyanobacteria which used and still use a process called photosynthesis to convert carbon dioxide and water into sugar and oxygen. The sugar is then used to build cell walls and in the metabolism. When plants evolved, they too carried out photosynthesis, putting even more oxygen into the atmosphere. Prior to the evolution of cyanobacteria, the metabolisms of organism relied on anaerobic processes.
What happened to increase oxygen levels in Earths atmosphere?
One would have to look at the grand scheme of things. If oxygen here increased, CO2 (carbon dioxide) would decrease, as well as Nitrogen. If that happened more plant would die off. Their oxygen giving would be cut off. More storms would occur, then something interesting would happen. Since we breath out carbon dioxide, we would put carbon dioxide back into the atmosphere! Oxygen would decrease, carbon dioxide increase, and nitrogen would increase due to lighting storms. Balance would come back in play, as long as mad scientists don't try to artificially pump back CO2 and nitrogen. Who knows? Perhaps plants would come back!
How does the ocean affect the rate of accumulation of CO2 in the atmosphere?
Oceans act as a carbon sink, in fact they are the largest carbon sink absorbing about 1/4 of the CO2 we put into the air. However, with global warming considering that CO2 dissolves better in cold water there is a worry that the oceans will not be able to hold as much CO2 and will begin to release it into the atmosphere
Why has carbon dioxide concentration risen?
because they is more and more cars,buses,train in the world and loads off gasses Such as fumes
What 2 processes put carbon back into your atmosphere?
The two main processes that put carbon back into the atmosphere are the respiration of living organisms, including plants and animals, and the combustion of fossil fuels. Respiration releases carbon dioxide as a byproduct, while the burning of fossil fuels, such as coal, oil, and natural gas, releases carbon dioxide that has been stored underground for millions of years. Both processes contribute to the accumulation of carbon dioxide in the atmosphere, leading to climate change.
What processes put carbon is found in most of earths atmosphere?
because i don't now by meni
What is the role of volcanic eruption in nitrogen fixation?
they put carbon dioxide back in the atmosphere
Carbon is removed from the atmosphere and put into food through?
the carbon cycle
Wow many tons of carbon do you put into the atmosphere annually?
I have no clue. How much do you put in the atmosphere annually?

How do living organisms return carbon to the atmosphere?
They can in many ways including: - just breathing(CO2 into the atmosphere) - decomposing after they have died - burning fossil fuels livestock like cows can also put carbon back into the atmosphere as they excrete methane gas.
What is the advantage of using wind turbines rather than burning fossil fuel to produce electricity?
When energy is created from wind turbines the energy is created from the atmospheres wind currents and no chemical processes are required. With no chemical processes(burning) involved the atmospheres chemical composition is not altered. Burning fossil fuel, simply put is the chemical process of changing a form of concentrated carbon into heat and carbon dioxide. Ancient life on the planet absorbed the carbon dioxide from the atmosphere and time and natural processes sequestered the carbon from the ancient life into coal and oil reserves. When you burn the fossil fuel you are placing the carbon, that was once sequestered through the millions of years Earth has had life, back into the atmosphere thus changing the composition of the atmosphere. The results of putting the carbon back into the atmosphere is debated. Example A: A pin-wheel is attached to a generator. The wind blows the pin wheels blades and the generator makes electricity. This electricity runs into a coil and the energy is transferred into heat and you warm your hands up. Example B: You have a dead stick from a tree in your yard that grew for a year and fell off the tree. During that year the tree converted energy from the sun and the carbon from the air to create the stick. You burn the stick and warm your hand.
How is a cow eating grass part of the carbon cycle?
The cow eats the grass; as the grass regrows, it takes carbon dioxide from the atmosphere into its growing leaves and roots (along with other nutrients) and stores the carbon molecules in the soil. The cow that ate the grass also has to excrete her wastes, which turns back into the soil through the act of decomposition. She also releases carbon into the atmosphere, but it is quickly put back into the earth by the plants that breathe it in and exhale oxygen through the act of photosynthesis.
Why does the combustion of biomass release no net carbon into the atmosphere?
Biomass is vegetable matter, like unwanted parts of sugar cane (bagasse), as well as residue from tree felling and other things. When vegetation grows, it removes carbon dioxide (CO2) from the atmosphere. When the same material is burnt as biomass, that same CO2 is put back into the carbon cycle.
How does get put back into the air?
Oxygen is a "waste" byproduct of photosynthesis. Plants use sunlight to combine water and carbon dioxide into sugar and "excess" oxygen molecules, which is then released into the atmosphere (or ocean, in the case of algae).
How does an ice age lead to global temperatures rising?
An ice age will put more carbon into the atmosphere. The increase in carbon captures the Sun's energy and the planet begins to warm.
