Web2.3.1 Photochemical Smog. Photochemical smog is a brownish-gray haze caused by the action of solar ultraviolet radiation on atmosphere polluted with hydrocarbons and oxides of nitrogen. It contains anthropogenic air pollutants, mainly ozone, nitric acid, and organic compounds, which are trapped near the ground by temperature inversion. WebEarth's atmosphere is made up of a combination of gases. The major components of nitrogen, oxygen, and argon remain constant over time and space, while trace components like CO 2 and water vapor vary considerably over both space and time.

WebThe second major constituent of the present-day atmosphere is Oxygen (O 2), but it was absent in the Primordial Atmosphere. Where did all the O 2 come from? Molecular Oxygen (O 2) comes primarily from photosynthesis in plants and algae. The O 2 content of the atmosphere has increased from 1% to 21% during the past 600 Myr. Ozone (O 3): WebAlthough much less abundant than nitrogen and oxygen in Earth's atmosphere, carbon dioxide is an important constituent of our planet's air. A molecule of carbon dioxide (CO 2) is made up of one carbon atom and two oxygen atoms. Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere. taran tekst
