Read the following statements and select the correct option.


Statement 1: Ozone layer present in the stratosphere protects the living organisms from harmful UV rays coming from the sun by absorbing nearly all of them.

Statement 2: Ozone formed in the troposphere by photochemical reactions as a result of human activities which is harmful to all living organisms.

commercial applications global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

  1. Both statements 1 and 2 are correct.

  2. Statement 1 is correct but statement 2 is incorrect.

  3. Statement 1 is incorrect but statement 2 is correct.

  4. Both statements 1 and 2 are incorrect.

Show answer
Correct Option: A
Explanation:

'Good ozone' is found in the upper part of the atmosphere called the stratosphere and it act as a shield by absorbing ultraviolet radiations from the sun. UV rays are, highly injurious to living organisms. 'Bad ozone' is formed in the lower part of atmosphere called troposphere and it harms plants and animals.

The major ozone depleting substance out of the following is _____________.

commercial applications global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

  1. $ { CFC }{ s } $

  2. $ { O } _{ 2 } $

  3. Nitrogen

  4. All of these

Show answer
Correct Option: A
Explanation:

Ozone-depleting substances (ODS) are substances that react with ozone present in the stratosphere and destroy the same. The major Ozone-depleting substances are chlorofluorocarbons (14% of total depletion), nitrogen oxides (3.5% depletion), sulphur dioxide, halon, carbon tetrachloride, methyl chloroform, chlorine, etc.

Ozone depletion is occurring widely in ______________.

commercial applications global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

  1. Troposphere

  2. Stratosphere

  3. Ionosphere

  4. All of these

Show answer
Correct Option: B
Explanation:

Ozone depletion is occurring widely in the stratosphere, particularly marked over the Antarctic region.

So, The correct answer is (B)- Stratosphere.

Increasing skin cancer and high mutation rate are the result of _______________.

commercial applications global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

  1. Ozone depletion

  2. Acid rain

  3. $CO$ pollution

  4. $ { CO } _{ 2 } $ pollution

Show answer
Correct Option: A
Explanation:

Ozone depletion occurs widely in the stratosphere due to an increased amount of $ { CFC }{ s } $ which causes various types of skin cancer and mutations.

So, The correct answer is (A)- Ozone depletion.

Identify the harmful radiations emitted by the sun.

commercial applications global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

  1. Ultra violet

  2. Infra red

  3. Visible

  4. Radio waves

Show answer
Correct Option: A
Explanation:

The ultraviolet radiations are the harmful rays which are present in the sun rays. The radiations are emitted from the sun and are harmful to living organisms. The ozone layer prevents the entry of these radiations into the Earth's atmosphere. The depletion of the ozone layer allows the radiations to cause harm to the plants and animals on the Earth.

Thus, the correct answer is option A. 

The reduction in the amount of chlorofluorocarbons (CFCs) released into the air has had the greatest positive effect upon 

commercial applications global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

  1. Water pollution 

  2. Noise pollution

  3. Acid rain 

  4. The ozone layer

  5. Endangered species

Show answer
Correct Option: D
Explanation:

The presence of CFCs in the atmosphere results in the depletion of the ozone layer. They are used as coolants in refrigerators, coolers, etc. The CFCs causes the breaking of the ozone molecule which forms the oxygen radical and O$ _2$. The depletion of the ozone layer results in the penetration of the harmful UV radiations from the sun into the Earth's atmosphere. The reduction in the use of the CFC molecules will prevent the ozone thinning and have the positive effect on the ozone layer. 

Thus, the correct answer is option D. 

The stratospheric ozone depletion leads to

commercial applications global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

  1. Global warming

  2. Increase in the incidence of skin cancers

  3. Forest fires

  4. All of the above

Show answer
Correct Option: D
Explanation:
Thinning of ozone layer increases the amount of UV-B radiations reaching the earth. This may lead to incidences of cataract, skin cancers, photo burning etc. Decreased photosynthetic activity will increase carbon dioxide concentration of the atmosphere resulting in global warming. Increased exposure of radiations may also lead to forest fires especially during dry summers.
So, the correct answer is 'All of the above'

In coming years, skin related disorders will be more common due to:

commercial applications global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

  1. Pollutants in air

  2. Use of detergents

  3. Water pollution

  4. Depletion of ozone layer

Show answer
Correct Option: D
Explanation:

Thinning of ozone layer increases the amount of ultraviolet radiations reaching the earth surface. The increased UV-B radiation increases incidence of cataract, skin cancers herpes, dimming of eyesight, photo burning, snow blindness and deficient functioning of immune system.
