Question

Checking of re-radiation heat by atmospheric dust, $O_3,O_2$ and water vapours is

• A. Ozone layer effect
• B. Solar effect
• C. Radioactive effect
• D. Green house effect

Answer 1

The correct option is D Green house effect

The greenhouse effect can be defined as the trapping of radiations of the sun by the tropospheric gases and preventing these radiations from reflecting back to space. The tropospheric gases involved are atmospheric dust, Ozone, Carbon dioxide and water vapour. These gases are responsible for causing global warming.

A. Ozone layer effect occurs in stratosphere only because of ozone.

B. Solar effect is caused due to solar flares.

C. The radioactive effect is due to radioactive elements like uranium and plutonium.

D. The greenhouse effect is due to greenhouse gases.

Hence, the correct answer is 'Greenhouse effect.'
