What is Ozone ? How and where is it formed in the atmosphere ? Explain how does it affect an ecosystem. |

Answer» Ozone is a molecule containing three atoms of oxygen (O3), a highly poisonous gas present in the upper layer of the atmosphere. Formation of Ozone : The UV radiations split molecular oxygen (O2) apart into free oxygen atoms (O + O). These atoms then combine with molecular oxygen to form ozone. O2 → O + O O + O2 → O3 Effect : Ozone layer shields the surface of the earth from damaging UV radiations of the sun. |
