Current Question (ID: 17836)

Question:

$\text{Ozone is a very toxic gas and a strong oxidizing agent. It is still useful for life on earth:}$

Options:

1. $\text{because it traps harmful UV-rays.}$
2. $\text{because it balances global warming.}$
3. $\text{because it traps harmful X-rays.}$
4. $\text{because it traps harmful } \gamma\text{-rays.}$

Solution:

$\text{The ozone layer in the stratosphere is a natural feature of the earth's environment.}$ $\text{The ozone layer exists between 20 \text{ to } 35 \text{ km above the earth's surface layer.}}$ $\text{This layer protects the earth from the harmful effects of the ultraviolet radiation of the sun.}$ $\text{Depletion of the ozone layer is considered a serious threat to all forms of life on the earth.}$ $\text{A 5\% decrease in ozone concentration could increase the incidence of skin cancer by 20\%.}$ $\text{Ultraviolet radiation is also the factor for the disease of the eye, including cataract formation.}$ $\text{It can cause genetic mutations and destroy crops and other forms of vegetation.}$ $\text{Aquatic animals and aquatic plants are generally affected by UV radiation.}$
