Name the two forms of oxygen element found in atmosphere. Which one among them grievuing depleted?state and explain the reason?

  • Science -

    I do not know what your word "grievuing" is supposed to mean.

    There are both O2 and O3 in the atmosphere. O3 (ozone) is present at very high altitudes (10-40 km) where is is produced by sunlight but simultaneosly depleted by chemical reactions involving byproducts of chlorofluorocarbons. Close to the ground, in polluted urban areas, it is also an ingredient of smog, causing eye and lung irritation.

    The ozone at high altitudes performs a beneficial role in greatly reducing the amount of harmful far-ultraviolet radiation that reaches the surface of the earth.
