Questions Related to pollution and its effects
Warm ocean surge of Peru current recurring every 5-8 years or so in the East Pacific of South America is widely known as.

Gulfstream

The best solution to combat greenhouse effect is
-
To use diesel vehicles
-
To stop infra-red from entering the earth
-
Afforestation and growing abundant plants
-
All of the above
The greenhouse effect is the phenomenon in which the greenhouse gases trap the heat in the Earth's atmosphere which results in an increase in the temperature. Carbon dioxide is one of the greenhouse gases which is utilised by the green plants for the purpose of photosynthesis. This results in the reduction of the greenhouse gases and thereby, the global warming. So, the greenhouse effect can be reduced by growing new plants through the process of afforestation.
Greenhouse effect corresponds to
-
Water pollution
-
Global warming
-
$SO _2$ poisoning
-
Production of green manure
The greenhouse effect is the phenomenon in which the percentage of poisonous gas like sulphur dioxide, carbon dioxide, carbon monoxide etc. increases which traps the heat in the Earth's atmosphere. The greenhouse gases are NO$ _2$, methane, CO$ _2$, water vapour and ozone. The increase in the heat in the Earth's atmosphere results in the global warming.
World climate is threatened by increase in the concentration of
-
Oxygen
-
Nitrogen
-
Water vapours
-
Carbon dioxide
Level of carbon dioxide is continuously increasing in the air due to its constant release by burning of fossil fuels in automobiles, industries etc. As a result, the temperature of the earth is on a constant rise. This has led to global warming and the greenhouse effect. The ozone layer is getting depleted causing harmful UV rays to reach the earth and cause serious ill effects. Apart from this, glaciers are constantly melting due to increase in temperature.
Which of the following is not a green house gas ?
-
Methane
-
Carbon dioxide
-
Nitrous oxide
-
Ammonia
Ammonia is not a green house gas. Methane, carbon dioxide and nitrous oxide are all greenhouse gases. They contribute to the greenhouse effect. Ammonia has no effect on the green house effect. So, option D ammonia s the correct answer.
All of these will directly or indirectly reduce the contribution to greenhouse gases except
-
Encouraging the use of public transportation
-
Walking
-
Biking
-
Increasing the cost of car ownership and fuel costs
-
Creating car-free zones
Which one of the following pairs in mismatched-
-
Nuclear power radioactive wastes
-
Solar energy green house effect
-
Fossil fuel burning release of $CO _{2}$
-
Biomass burning release of $CO _{2}$
The reason for green-house effect is
-
Higher $CO _2$ concentration causing global warming
-
Absorption of infra-red rays by gases and dust particles
-
Both A and B
-
Rarefaction of $CO _2$
Green house effect is increasing due to
-
Increasing $CO _2$ concentration
-
Increasing $SO _2$ concentration
-
Increasing concentration of chlorofluorocarbons
-
Hole in ozone layer
The higher concentration of carbon dioxide in the atmosphere is likely to increase the temperature as carbon dioxide permits the short wavelength visible radiations to pass through it but traps the longer wavelength infrared radiation reflected by earth's surface. This is called the greenhouse effect and it results in the overall increase in the global temperature, called global warming. Carbon dioxide contributes to the 81% of the greenhouse gases because it tends to persist in the atmosphere.
Checking of re-radiation heat by atmospheric dust, $O _3, O _2$ and water vapours is
-
Ozone layer effect
-
Solar effect
-
Radioactive effect
-
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.
