The various processes that occur during the cycling of water are illustrated in Figure 3. The processes include the following: evaporation and sublimation. condensation and precipitation.
WebThe carbon cycle is fully coupled to the oxygen cycle. Each year, photosynthesis fixes carbon dioxide and releases 100,000 megatons of oxygen to the atmosphere. Respiration by animals and living organisms … 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 oxygen and carbolic acids (HxCO3).
