E Correct answer
Explanation
  • Greenhouse gasses generally traps the radiations of the earth which leads to an increase in the temperature of the earth and global warming.
  • The greenhouse gasses include water vapor, carbon dioxide, methane, nitrous oxide, and ozone.

So, the correct answer is option E.

Which one of following pairs of gases is the major cause of greenhouse effect?

  1. $CO _2$ and $O _3$
  2. $CO _2$ and $CO$
  3. $CFC$ and $SO _2$
  4. $CO _2$ and $N _2O$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The major greenhouse gases responsible for greenhouse effect are carbon dioxide, ozone, methane and water vapour. These gases acts like a thick warm blanket outside that surrounds this planet and regulates climate control. Water vapour causes about 36-70% of the greenhouse effect on earth, carbon dioxide CO$ _2$, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%.

Therefore, the correct answer is option A.

Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect 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.

  1. Gulfstream

  2. Aye Aye

  3. El Nino

  4. Angox
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
El Nino is a climate cycle in the Pacific Ocean with a vast impact on global weather patterns. It begins when warm water in the western tropical Pacific Ocean shifts eastward along the equator toward the coast of South America more specifically Peru. This warm water pools near Indonesia and the Philippines. It recurs every 5-8 years. Thus, 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 growing abundant plants

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

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.

Thus, the correct answer is option C.

Greenhouse effect corresponds to 

  1. Water pollution

  2. Global warming
  3. $SO _2$ poisoning

  4. Production of green manure
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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. 

Thus, the correct answer is option B. 

Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect pollution and its effects

World climate is threatened by increase in the concentration of

  1. Oxygen

  2. Nitrogen

  3. Water vapours

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

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.

So, option D " Carbon dioxide" is the correct answer.

Which of the following is not a green house gas ?

  1. Methane

  2. Carbon dioxide

  3. Nitrous oxide

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

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.

Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect pollution and its effects

All of these will directly or indirectly reduce the contribution to greenhouse gases except 

  1. Encouraging the use of public transportation

  2. Walking

  3. Biking

  4. Increasing the cost of car ownership and fuel costs

  5. Creating car-free zones
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
A. Encouraging the use of public transport will reduce air pollution as this will lead to less use of cars and other personal transport vehicles. If many people instead of travelling by their personal transport vehicle, will use the public transport, then there will be less emission of green house gases.
B. Walking instead of using a vehicle for travelling can also reduce green house gases emission as no transport vehicle will be used and no harmful gases will be released.
C. Biking will contribute to air pollution as green house gases like carbon dioxide are released as the fuel is burnt in the engine of the bike.
D. Increasing the cost of car ownership and fuel costs will tend to decrease in use of less cars as people won't spend much money for this. So, this will also decrease the air pollution and the emission of green house gases.
E. Creating car free zones will make the people to avoid the use of cars and thus, this will also prevent the emission of green house gases.
Hence, all the options except biking, will directly or indirectly reduce the contribution to green house gases.
So, the correct answer is 'Biking'.

Which one of the following pairs in mismatched-

  1. Nuclear power radioactive wastes

  2. Solar energy green house effect
  3. Fossil fuel burning release of $CO _{2}$
  4. Biomass burning release of $CO _{2}$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Solar energy decreases greenhouse gas emissions. Generating electricity with solar power instead of fossil fuels can dramatically reduce greenhouse gas emissions, particularly carbon dioxide (C$O _2$). Greenhouse gases, which are produced when fossil fuels are burned, lead to rising global temperatures and climate change.

So, the correct answer is 'Solar energy green house effect'.
Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect pollution and its effects

The reason for green-house effect is

  1. Higher $CO _2$ concentration causing global warming

  2. Absorption of infra-red rays by gases and dust particles

  3. Both A and B
  4. Rarefaction of $CO _2$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
A minor but very important component of atmospheric carbon dioxide is released through natural process viz., Respiration, volcanic eruption. Humanly induced activities as deforestation, burning fossils, land use changes are major causes for the release of greenhouse gases in the atmosphere.
The greenhouse gases absorb infrared radiation from the sun and trap some of the radiation. Excess of these gases can force climate change drastically.
Hence, the correct answer is 'Both A and B'.
