Questions Related to causes of greenhouse effect

Identify the correct matching combination.

I II III
(a) Chernobyl Accidental leakage Radioactive waste
(b) El Nino effect Global warming Causes climate changes
(c) Chlorofluorocarbons Ozone degradation Fluorine atoms released
(d) Snow blindness UV-B radiation Inflammation of cornea
  1. a, c

  2. a, d

  3. a, b, d

  4. b, d


Correct Option: C
Explanation:
  • The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986, in the No. 4 nuclear reactor at the Chernobyl Nuclear Power Plant, near the city of Pripyat, in the north of the Ukrainian SSR. Which resulted in accidental leakage of radioactive wastes into the surrounding atmosphere which caused a large number of loss of human life and many genetic disorders due to radioactive mutations.
  • El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean. El Nino is the “warm phase” of a larger phenomenon called the El Nino-Southern Oscillation (ENSO). It results in climate change.
  • Snow blindness is a painful, temporary loss of vision due to overexposure to the sun's UV -B rays. Its symptoms include inflammation of the cornea.
  • So, the correct answer is 'a,b,d'.

Which of the following sectors can possibly be affected by the onset of EI-Nino?
$1$. Food processing industries
$2$. Irrigation sector
$3$. Power sector
Choose the correct answer using the codes.

  1. $1$ and $2$

  2. $2$ and $3$

  3. $1$ and $3$

  4. All of the above


Correct Option: B
Explanation:

El Niño Southern Oscillation refers to the cycle of warm and cold temperatures, as measured by sea surface temperature (SST) of the tropical central and eastern Pacific Ocean. El Niño is accompanied by high air pressure in the western Pacific and low air pressure in the eastern Pacific. These changes in tropical rainfall affect weather patterns throughout the world, particularly for the national agriculture, fishing, forestry, and energy sectors.


So the correct option is '2 and 3'.

Multiple Choice Questions
Which one of the following is mismatched?

  1. Fossil fuel burning - Release of $CO _2$

  2. Nuclear power - Radioactive wastes

  3. Solar energy - Green house effect

  4. Biomass burning - Release of $CO _2$


Correct Option: C
Explanation:

The greenhouse effect is a naturally occurring phenomenon responsible for heating surface and atmosphere of earth. It is caused due to the presence of greenhouse gases like CO$ _2$, CH$ _4$ and CFCs etc. An excess amount of these gases cause global warming. The greenhouse gases are responsible for the greenhouse effect.

So, the correct answer is option C, solar energy - greenhouse effect.

At night, low clouds:

  1. Enhance the atmospheric greenhouse effect

  2. Weaken the atmospheric greenhouse effect

  3. Are often caused by the atmospheric greenhouse effect

  4. Have no effect on the atmospheric greenhouse effect


Correct Option: A

The planet with a strong greenhouse effect, whose surface temperature averages $480^{o}C$ $(900^{o}F)$ is :

  1. Earth

  2. Venus

  3. Mars

  4. Pluto


Correct Option: B

The heating of earth's atmosphere due to trapped radiation is known as

  1. Global warming

  2. Glass-House effect

  3. Thermal effect

  4. Green House effect


Correct Option: D

What can humanitarian be harmed by unmitigated greenhouse emissions?

  1. Severe weather

  2. Infectious diseases

  3. Food crises

  4. All of above


Correct Option: D

Fourier predicted the green house effect and it was coined by

  1. Fourier

  2. Tanseley

  3. Arrhenius

  4. Odum


Correct Option: C
Explanation:

The burning of fossil fuels leads to increase in the concentration of carbon dioxide levels in the atmosphere. Svante Arrhenius (1859-1927) was a Swedish scientist who was the first to claim in 1896 that fossil fuel combustion may eventually result in enhanced global warming. He proposed a relation between atmospheric carbon dioxide concentrations and temperature. He found that the average surface temperature of the earth is about $15^0$C because of the infrared absorption capacity of water vapour and carbon dioxide. This is called as the natural greenhouse effect. 

So, the correct answer is option C.

The best solution to combat greenhouse effect is

  1. To use diesel vehicles

  2. To stop infra-red from entering the earth

  3. Afforestation and grow abundant plants

  4. All of the above


Correct Option: C
Explanation:

The best solution to combat greenhouse effect is to plant trees. Trees absorb carbon dioxide and give off oxygen. A single tree will absorb approximately one ton of carbon dioxide during its lifetime.

CO$ _2$, CH$ _4$, N$ _2$O and CFCS are called as green house gases because they can absorb

  1. Ultraviolet radiation

  2. Long wave infrared radiation

  3. Visible light radiation

  4. X-rays radiation

  5. $\gamma$-rays radiation


Correct Option: B
Explanation:

Greenhouse gases are the gases which contribute to global warming. When the concentration of these gases increases in the atmosphere they form a layer which traps the solar radiation. Due to the trapped long wave infrared radiation, the temperature of the earth increases which leads to global warming. So the correct answer is option C.
