Multiple choice zoology global environmental change causes of greenhouse effect global warming adaptation in animals

Which is not correct approach to reduce global warming?

  1. Cutting down use of fossil fuel

  2. Reducing deforestation

  3. Improving efficiency of energy use

  4. Cutting trees and increasing growth of human population

  5. Reducing emission of greenhouse gases into atmosphere
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
To avoid Global Warming: 
1) By utilizing eco-friendly vehicles. 
2) Replace normal glowing light with conservative bright light (CFL) knobs. 
3)Plant more trees. By planting more trees helps in decreasing a dangerous atmospheric deviation as plants use carbon dioxide amid the procedure of photosynthesis, which is the primary driver of Global warming. 

So, the correct option is 'Cutting trees and increasing the growth of the human population'.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • As individuals, we can help by taking action to reduce our personal carbon emissions.
  •  But to fully address the threat of global warming, we must demand action and support and implement a comprehensive set of climate solutions:
  •  Expand the use of renewable energy and transform our energy system to one that is cleaner and less dependent on coal and other fossil fuels.
  •  Increase vehicle fuel efficiency and support other solutions Place limits on the amount of carbon that polluters are allowed to emit. 
  • Build a clean energy economy by investing in efficient energy technologies, industries, and approaches. 
  • Reduce tropical deforestation and its associated global warming emissions.
  • Hence, Increasing the use of air conditioners, refrigeration unit and production of plastic foams and propellants in aerosol spray cans is not a correct approach to reduce global warming. 
  • So, the correct answer is 'Increasing the use of air conditioners, refrigeration unit and production of plastic foams and propellants in aerosol spray cans'.

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.
Reveal answer Fill a bubble to check yourself
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.'

Multiple choice commercial applications management of natural resources unequal distribution of resources protecting our environment rules are for everyone

Advantage of energy plantations is

  1. Running nuclear plants

  2. To reduce pressure on fossil fuel

  3. To decrease soil erosion and pollution

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Energy plantation is the method in which there is the cultivation of certain species of the plants which can be used as the source of energy. They can be used as an alternative to the fossil fuels. This reduces the pressure on the fossil fuels. 

Due to the plantation, there is the decrease in the problems like soil erosion. The pollution caused due to the decrease in the number of trees is also reduced.
Thus, the correct answer is option D.

Which is not the possible solution for energy crisis?

  1. Wars and attacks

  2. Energy Simulation

  3. Perform energy audit

  4. Common stand on climate change
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

An electricity shortage is felt most acutely in heating, cooking, and water supply. Therefore, a sustained energy crisis may become a humanitarian crisis.

If an energy shortage is prolonged a crisis management phase is enforced by authorities. Energy audits may be conducted to monitor usage. Various curfews with the intention of increasing energy conservation may be initiated to reduce consumption.

Wars and attacks do not solve the problem of energy crisis, on the contrary they destroy the potential sources of energy.

Which one of these are not the reasons for energy crisis?

  1. Overconsumption

  2. Poor infrastructure

  3. Energy simulation

  4. Poor distribution system
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Energy simulation software can be used by big corporates and corporations to redesign building unit and reduce running business energy cost. Engineers, architects and designers could use this design to come with most energy efficient building and reduce carbon footprint. Hence it cannot be the reason for energy crisis, rather it is the solution to energy crisis.

What can be the solution of energy crisis?

  1. Wars and attacks

  2. Major accidents and natural calamities

  3. Poor distribution system

  4. Common stand on climate change
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Both developed and developing countries should adopt a common stand on climate change. They should focus on reducing greenhouse gas emissions through an effective cross border mechanism. With current population growth and over consumption of resources, the consequences of global warming and climate change cannot be ruled out. Both developed and developing countries must focus on emissions cuts to cut their emission levels to half from current levels by 2050.

If energy is conserved then why there are energy crisis?

  1. Energy can be lost through heat

  2. Different sources of energy can lost their efficiency with time

  3. Energy can neither be created nor destroyed, but it does change its form. And not all forms of energy are usable and it gets dissipated as heat energy and sound energy

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

Energy can neither be created nor destroyed, but it does change its form. And not all forms of energy are usable and it gets dissipated as heat energy and sound energy. The energy that is wasted cannot be recovered. Moreover, the current sources or energy such as fuels are non-renewable in nature and are rapidly consumed. That is why we are facing energy crisis.
