Earth oxygen cycle
Oxygen cycle refers to the movement of oxygen through the atmosphere (air), biosphere (plants and animals) and the lithosphere (the Earth’s crust). The oxygen cycle demonstrates how free oxygen is made available in each of these regions, as well as how it is used. The oxygen cycle is the biogeochemical … See more The atmosphere is 21% oxygen by volume, which equates to a total of roughly 34 × 10 mol of oxygen. Other oxygen-containing molecules in the atmosphere include ozone (O3), carbon dioxide (CO2), water vapor (H2O), … See more The biosphere is 22% oxygen by volume, present mainly as a component of organic molecules (CxHxNxOx) and water. See more The lithosphere is 46.6% oxygen by volume, present mainly as silica minerals (SiO2) and other oxide minerals. See more The presence of atmospheric oxygen has led to the formation of ozone (O3) and the ozone layer within the stratosphere: $${\displaystyle \mathrm {O_{2}+uv~light\longrightarrow 2~O} \qquad (\lambda \lesssim 200~{\text{nm}})}$$ See more The hydrosphere is 33% oxygen by volume present mainly as a component of water molecules, with dissolved molecules including free … See more While there are many abiotic sources and sinks for O2, the presence of the profuse concentration of free oxygen in modern Earth's atmosphere and ocean is attributed to O2 production … See more • Carbon cycle • Nitrogen cycle See more WebMost of our atmosphere is actually nitrogen, 78 percent, you don't talk a lot about it. And oxygen, 21 percent. And then a bunch of other, a bunch of other elements and molecules. But the very simple version of the carbon cycle is, okay, you have this atmospheric carbon dioxide, molecular carbon dioxide, hanging out in the air.
