Which is not a proper strategy to reduce global warming?

  1. Developing substitutes of chlorofluorocarbons.

  2. Increasing use of air conditioners, refrigeration units and production of plastic foams and propellants in aerosol spray cans.

  3. Minimising use of nitrogen fertilizers in agriculture for reducing nitrogen oxide emission.
  4. Increase vegetation cover, particularly forest, for photosynthetic utilisation of $CO _2$.

  5. Reducing green house gas emission by limiting use of fossil fuels.

B Correct answer
Explanation

Global warming refers to the overall increase in the tropospheric temperature reflected on the earth's surface. Developing substitutes for chloroform will not allow the build of chloroforms in the atmosphere. Minimal use of nitrogen fertilizers will not allow nitrogen oxides to cause secondary pollutants. Increase in vegetation like forests will make sure that carbon dioxide is used and so it will not cause the greenhouse effect. Limited use of fossil fuels will not add carbon dioxide, methane, oxides of sulphur etc and thus environment can be saved from their deleterious effects. On the other hand increase use of ACs, refrigerators, production of plastic forms and aerosol spray can propellants are harmful to the environment in a great deal because they cause ozone hole as well as global warming.

Hence, the correct answer is 'Increasing use of air conditioners, refrigeration units and the production of plastic foams and propellants in aerosol spray cans.'

Kyoto protocol is a multination international treaty for

  1. phasing out greenhouse gases

  2. controlling ozone destroying substances

  3. management of hazardous wastes

  4. conservation of biodiversity
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Kyoto protocol is an international treaty which extends the 1992 united nations framework convention on climate change (UNFCC) that commits state parties to reduce greenhouse gas emissions, based on the scientific consensus that global warming is occurring.

So, the correct option is Phasing out greenhouse gases.

Multiple choice physics energy production causes of greenhouse effect global warming adaptation in animals

The increase of carbon dioxide gas in atmosphere will cause

  1. decrease in temperature

  2. increase in temperature

  3. no change in temperature

  4. nothing can be said
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Carbon dioxide is main cause of green house effect. The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbondioxide, nitrous oxide, ozone, methane, for example) trap energy that comes from the sun.
Thus, increase of carbon dioxide gas in atmosphere will cause increase in temperature.

The average temperature of the Earth remains fairly steady as compared to that of the moon because of the

  1. atmosphere

  2. lithosphere

  3. biosphere

  4. hydrosphere
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The average temperature of the earth remains fairly steady as compared to that of the moon because of the earth's atmosphere. Atmosphere of earth absorbing ultraviolet solar radiation, warming the surface through heat retention (green house effect), and reducing temperature extremes between day and night. Moon has no atmosphere.

The global warming has resulted in :

  1. the increase in yield of crops

  2. the decrease in sea levels

  3. the decrease in human deaths

  4. the increase in sea levels
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The effects of an increase in global temperature include a rise in sea level rise (due to melting of snow and ice and because water above 3.98 C expands as it warms), widespread melting of snow and ice, increased heat content of the oceans, increased humidity, and the earlier timing of spring events.
Option D is correct.

Name the radiation which are absorbed by the green house gases.

  1. X-ray

  2. Ultraviolet

  3. Visible

  4. Infrared
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

    The short wavelength (high frequency) infrared radiations  come from sun to earth's surface and after reflection from surface , turn into long wavelength infrared radiations , these long wavelength radiations are absorbed by green house gases .

What is the best thing to do when strong winds are blowing over a hut having a weak thatched roof ?

  1. Open the doors and windows

  2. Close all the doors and windows

  3. Make holes in the roof

  4. Burn wood inside
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The correct answer is option(A).

High speed winds reduces the pressure above the roof. While the air pressure below the roof is high which pushes the roof upwards. To avoid this we have to open the doors and windows so that air is moving leading to lower pressure in the hut.

What will be the effect of global warming at the poles?

  1. Decreasing of temperature

  2. Increasing of temperature

  3. constant of temperature

  4. none of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Due to global warming the temperature of earth's atmosphere in increasing, and the temperature at poles is also increasing. This increase in temperature at poles will melt the ice on poles , and will melt the glaciers and after some time the poles will be iceless. This will result in increase in the level of oceans which in turn may sink the coastal land areas.
