What are the major sources of C in our atmosphere?
How long does co2 remain in the atmosphere
What evidence is there that plants make there own food using energy from the Sun?
The process called photosynthesis takes carbon dioxide from the atmosphere and energy from the Sun's rays to separate out carbon and oxygen. The carbon is used to form the long organic molecules that make up the body of the plant, while the oxygen is mainly released back into the atmosphere. That's how we have oxygen to breathe, and without plants mammal life would never have been possible. Later the plant tissue (e.g. wood) can be burned, and this reunites the carbon and oxygen atoms to produce heat and carbon dioxide. This can also happen after millions of years after the plants have decomposd and fossilised, and this is the origin of the term 'fossil fuel'.
How long has oxygen been fully present in the atmosphere?
500 million years
Do the percentages of gases in your atmosphere change?
Over long periods of time the concentrations of some gasses such as oxygen and carbon dioxide do change. Water vapor is even more variable, often changing on a daily or hourly basis.
Can you breathe on Mars?
Not without the aid of a breathing apparatus. Mar's atmosphere is nearly 96 % carbon dioxide.Humans cannot breathe on Mars. The atmosphere is thin and made almost entirely of carbon dioxide, a poisonous gas.Without being encapsulated with an oxygen supply? If you did it wouldn't be long before you were not breathing at all.The atmosphere is mostly carbon dioxide (what we breathe out), and very tiny amounts of oxygen (what we breathe in). So air there does not have what we need, to breathe it successfully, but that's not the entire problem. Mars is also very cold. In fact you'd freeze to death before realizing that you were suffocating.No you could not breath the air on Mars, first the atmosphere is very thin (it is at a very low pressure 0.6 kPa, compared to Earth's 101.3 kPa) and second the atmosphere contains no oxygen.The atmosphere on Mars consists of 95% carbon dioxide, 3% nitrogen, 1.6% argon. The atmosphere is also quite dusty, giving the Martian sky a tawny color when seen from the surface.
What two sources take CO2 out of the atmosphere?
The ocean removes carbon dioxide (CO2) from the atmosphere as part of the carbon cycle. This carbon recycles round and returns to the atmosphere again.Trees, forests and all growing vegetation remove CO2 from the atmosphere, release the oxygen, and store the carbon. If it is a long living tree, it can store that carbon for hundreds of years.
Is the atmosphere a carbon store?
yes the atmosphere is a long term carbon store
What are the major sources of C in our atmosphere?
How long does co2 remain in the atmosphere
Is there carbon in the earths atmosphere?
yes. carbon monoxide is one carbon and one oxygen carbon dioxide is one carbon and two oxygens methane is one carbon and 4 hydrogens any hydrocarbon is a long chain of carbon and hydrogen there are many other forms
What is carbon monoxide cycle?
Carbon monoxide is first produced by either human activities involving combustion or a variety of natural processes. From there on, it reacts with oxygen/hydrogen radicals in the atmosphere and become carbon dioxide. The fact that most carbon monoxide will become carbon dioxide when left in the atmosphere long enough can help explain why the carbon monoxide cycle is not taught in school.
Where does oxygen comes from?
Oxygen is chemically released through photosynthesis in green plants. The atoms of oxygen, however, were created in the cores of stars that exploded long before our Solar System began to form
How long does carbon remain in some stages of the cycle?
because
Chemical elements of fats?
Normally only Carbon, Hydrogen and Oxygen They are effectively hydrocarbon chains held together by ester bonds ("oxygen joints")
How is oxygen kept in the atmosphere?
Physically kept there? By gravity, same as all other atmospheric gases.Chemically kept there in spite of its reactive nature? It's not, really. Atmospheric oxygen readily reacts chemically with other substances all the time. However, plants are continually pumping new oxygen into the atmosphere via photosynthesis in opposition to that trend, and the two processes roughly cancel each other out. (Or did, before combustion of fossil fuels started increasing carbon dioxide concentrations since the dawn of the industrial era.)If it weren't for photosynthesis, a reactive gas like oxygen would not long remain a component of the Earth's atmosphere.
Why does air never fill up with carbon dioxide?
Ninety-nine percent of the atmosphere is already filled with nitrogen and oxygen, and carbon dioxide makes up less that 1% of the rest. So it will take a long time for the air to fill up with carbon dioxide.

How long does air take to form?
It is not entirely clear what you have in mind by this question. The planet Earth has had an atmosphere for the past four and a half billion years, but the composition of the atmosphere changes constantly, with everything that is added to it or subtracted from it. Plants release oxygen from photosynthesis, people release carbon dioxide from burning fossil fuels, volcanoes release various gases, etc. All of this happens all the time. If you want to know how long it would take an airless planet to develop an atmosphere, the answer would be, airless planets usually remain airless.
