(d) How does ozone layer protect living beings on earth?
(a) The molecular formula of ozone is O3.
(b) It is formed by the action of ultraviolet rays of the Sun on oxygen.
O3 → O + O2
The ozone layer acts as a blanket in the atmosphere 16 km height above the Earth's surface.
It absorbs harmful ultraviolet rays (UV radiations) coming from the Sun and prevents them to reach the surface of the Earth.
(c) Excessive use of chlorofluro carbon: It is released by refrigerators and air conditioning systems.
It causes a reduction of the ozone layer that protects us from harmful ultraviolet rays (UV radiations) of the Sun.
The fuel of planes: The burning of fuels in planes emits a large quantity of nitric oxide and other gases in the atmosphere. Nitric oxide reacts with ozone and forms nitrogen dioxide and nitrogen trioxide. This causes depletion of ozone.
(d) Ozone layer acts as a blanket in the atmosphere 16 km height above the Earth's surface.
It absorbs harmful ultraviolet rays (UV radiations) coming from the Sun and prevents them to reach the surface of the Earth.
Ultraviolet rays have very harmful effects on living things. It causes skin cancer. It destroys many organic species which are necessary for life.
Thus it protects the life on earth from the harmful effects of Ultra Violet Rays. Which can cause
(a) Skin cancer
(b) destroy many organic species necessary for life.
