Some people are surprised to learn that oxygen isn''t the most abundant gas in Earth''s atmosphere composition.
Based on the relative volumes of the gases in Earth''s atmosphere, nitrogen is actually more than 3 times more than oxygen.
Because the troposphere is the lowest atmosphere layer, it contains 75 percent of the atmosphere’s mass.
From largest to smallest, Earth''s atmosphere composition contains nitrogen, oxygen, argon, CO2, and trace gases. Because water vapor is highly variable geographically, it''s excluded from this total.
While nitrogen is the most abundant gas in Earth’s atmosphere, it only makes up 0.005% of Earth’s crust in weight (David Darling).
Nitrogen is incredibly stable and requires a lot of energy to change forms.
Even though its volume in Earth’s crust is relatively small, nitrogen plays an important role in the nitrogen cycle.
As part of this cycle, nitrogen constantly exchanges between the atmosphere and living organisms.
Earth has the conditions for life to flourish. Oxygen is essential to human life as our lungs respire oxygen and uses it in metabolism.
So even though nitrogen is plentiful, we need oxygen to drive chemical reactions that produce energy.
As an inert gas, argon doesn’t bond or do much in the atmosphere.
This is why there’s no argon cycle. But we have nitrogen and carbon because of their ability to bond with other elements.
When potassium radioactively decays, argon is one of the possible products. And the lithosphere has lots of potassium.
It’s not too exciting of a gas. But it’s up in the atmosphere at 0.93% of air volume.
Carbon is the most important element for building molecules essential for living things.
As you can see from the long-term carbon cycle, carbon takes up various forms such as carbon dioxide (CO2), methane (CH4), and glucose (C6H12O6).
In turn, gases like methane and carbon dioxide become air pollution in the atmosphere. In fact, carbon dioxide has nearly doubled since 1900.
The remaining portion of the atmosphere belongs to trace gases. For example, neon, helium, methane, methane, and krypton are some of the major trace gases that make up a small part of the atmosphere.
But humans can also cause some trace gases. For example, chlorofluorocarbons (CFCs) has damaged the ozone layer in the north and south pole.
When chlorine enters the troposphere and eventually the stratosphere, it reacts with ozone (O3) essentially depleting it. Similar to ozone, water vapor is a variable gas.
Water vapor has been removed from the 100% total because of its region variability. But it can make up large portions of the atmosphere. For example, it can make up 5% by volume in hot regions but much less in colder regions.
Water vapor regulates air temperature because it absorbs solar radiation. It evaporates from lakes and rivers on the surface of Earth. Once it’s in the atmosphere, water vapor condenses such as in the form of rain. It simply changes form from water vapor to a liquid.
As part of the hydrological cycle, water is always in motion. And it''s all driven by the sun''s energy.
The main focus is how water is stored – in the atmosphere, glaciers, oceans, plants, and humans. Most evaporation takes place in oceans. It''s the Coriolis effect that moves it away from the equator.
In this video, it displays a year in the life of Earth’s carbon dioxide. As you can see, carbon dioxide is the most important gas affected by human activity.
In the northern hemisphere, we see the highest concentrations of carbon dioxide from major emission sources. For example, carbon emissions are mostly focused around North America, Europe, and Asia. But the gas disperses, finding its circulation path with global weather patterns and ocean currents.
Even the seasonal patterns on Earth affect the amount of carbon dioxide in the atmosphere. During photosynthesis in spring and summer, plants absorb a substantial amount of carbon dioxide from the atmosphere.
As summer transitions to fall, photosynthesis begins to decrease as carbon dioxide accumulates back into the atmosphere. This effect is from the Earth’s metabolism or net primary productivity.
The Earth’s atmosphere is made up of many different gases. At the lower levels, nitrogen and oxygen are the most abundant gases.
One of the most important things to remember about Earth’s atmosphere is that it is dynamic, meaning what we see today may not be the same as what we see years from now.
With ‘TERROR’ of excessive CO2 what is today’s breakdown? Or is that information ‘CONTROLLED’?
earthhow wrote: “The greenhouse effect is what traps heat globally and causes more overall warming.”
Wrong. The “greenhouse effect” is a manifestation of the wholly-fictive “backradiation”, which is a manifestation of the misuse of the Stefan-Boltzmann equation in Energy Balance Climate Models (EBCMs), which I prove using the Kiehl-Trenberth ‘Earth Energy Balance’ graphic (which is a graphical representation of the results of the mathematics in their EBCM).
Climatologists use the idealized blackbody form of the S-B equation upon real-world graybody objects in their EBCMs. The idealized blackbody form of the equation assumes emission to 0 K and thus it inflates radiant exitance for all calculated-upon objects, which conjures “backradiation” out of thin air. This “backradiation” is claimed to cause the “greenhouse effect”, which is used to designate polyatomics as “greenhouse gases”, which is used to claim certain of those polyatomics cause CAGW (Catastrophic Anthropogenic Global Warming, due to CO2).
Except “backradiation” implies energy spontaneously flowing up an energy density gradient, in violation of 2LoT in the Clausius Statement sense. “Backradiation” violates the fundamental physical laws… and if a physical process violates the fundamental physical laws, it is physically impossible. All of the offshoots of CAGW (net zero, carbon credit trading, carbon capture and sequestration, etc.) are based upon a physical impossibility. We are literally chucking money into a fire with this nonsense.
IOW, CAGW is nothing more than a complex mathematical scam. I unwind that scam and irrefutably prove with mathematical precision that it is nothing more than a scam at the link below:
This Is a LIE That The Progressive Loony Left Wants You To Believe. When John D. Rockefeller got into the Oil Business, he wanted people to believe that Oil was scarce, it is in fact the second most available liquid in the world other than water, and there is a lot of it, it’s not scarce, and thus why there’s an oil cartel to make sure they don’t release too much at one time and cheapen it’s value.
