Questions Related to causes of greenhouse effect

Which of the following organisation was created concerning about global warming?

physics heat and energy causes of greenhouse effect global warming adaptation in animals

  1. WNO

  2. WHO

  3. UNO

  4. UFO

Show answer
Correct Option: A
Explanation:

The World Nature Organization (WNO) is dedicated to the protection of the environment at international level. Its main focus is on energy efficiency, climate protection, sustainable development and a sustainable energy supply. As a permanent platform, the WNO tries to build bridges between business interests as well as development and environmental protection while, at the same time, making the economic value of nature apparent.

Which among the following is/are incorrect?

physics heat and energy causes of greenhouse effect global warming adaptation in animals

  1. Methane is more potent green house gas than $CO _2$

  2. Ruminants produce 80 million metric tons of methane annually.

  3. Global warming does not effect in agriculture and farming

  4. Methane is nearly 20 percentage responsible for global warming and 2/3 of methane is produced by animals.

Show answer
Correct Option: C
Explanation:

Global warming could affect agriculture and farming in several ways.

  • Higher $CO _2$ levels can affect crop yields. 
  • More extreme temperature and precipitation can prevent crops from growing. 
  • Dealing with drought could become a challenge in areas where rising summer temperatures cause soils to become drier.
  • Many weeds, pests, and fungi thrive under warmer temperatures, wetter climates, and increased $CO _2$levels.
  • Though rising $CO _2$ can stimulate plant growth, it also reduces the nutritional value of most food crops.
  • Heat waves, which are projected to increase under climate change, could directly threaten livestock.
  • Global warming may increase the prevalence of parasites and diseases that affect livestock.
  • Drought may threaten pasture and feed supplies. Drought reduces the amount of quality forage available to grazing livestock.

What can we do to stop climate change?

  1. Turn off the lights when you leave a room.

  2. Drive less. Instead, walk, ride your bike, or use public transportation if you can.

  3. Recycle used paper, cans, bottles, and other materials.

  4. All of these.

Show answer
Correct Option: D
Explanation:

All the deeds which will reduce the emissions of greenhouse gases will stop climate change.All the given options, directly or indirectly affects the concentration level of greenhouse gases.

Which of the following is the advantages of global warming?
A. Fewer deaths or injuries due to cold weather.
B. Longer growing seasons could mean increased agricultural production in some local areas.
C. Increased emigration of those from poorer or low-lying countries to wealthier or higher countries seeking better conditions.
D. Earlier drying of forests leading to increased forest fires in size and intensity.

physics heat and energy causes of greenhouse effect global warming adaptation in animals

  1. Only A and B

  2. Both B and C

  3. A, B and C

  4. All of the above

Show answer
Correct Option: A
Explanation:
The advantages of global warming are;

  • The Arctic, Antarctic, Siberia, and other frozen regions of the earth might experience more plant growth and milder climates.
  • The next ice age could possibly be prevented.
  • The Northwest passage through the formerly icy Canadian Arctic Archipelago could arguably open up to transportation.
  • Fewer deaths or injuries would occur due to arctic conditions.
  • Longer growing seasons could mean increased agricultural production in some areas.
  • Previously untapped oil and gas reserves might become available.

The migration of people derived from global warming will undoubtedly facilitate the migration of these pathogens, directly influencing public health and the economy (costs in prevention, control and treatment) and will have a negative impact on the world population. Also, increases in average annual temperatures create conditions that dramatically elevate the risk and severity of forest fires.

Global warming 

physics heat and energy causes of greenhouse effect global warming adaptation in animals

  1. has same effect throughout the world

  2. effects varies in different regions

  3. increase with the increasing in pressure

  4. none of the above

Show answer
Correct Option: B
Explanation:

The world average temperature is rising due to the greenhouse effect caused by increasing levels of greenhouse gases, especially carbon dioxide. When the global temperature changes, the changes in climate are not expected to be uniform across the Earth. In particular, land areas change more quickly than oceans, and northern high latitudes change more quickly than the tropics, and the margins of boime regions change faster than do their cores.

The ozonosphere absorbs the

physics heat and energy causes of greenhouse effect global warming adaptation in animals

  1. Visible light

  2. Microwaves

  3. Infrared radiation

  4. Ultraviolet radiations

Show answer
Correct Option: D
Explanation:

The ozonosphere contains a layer of ozone gas which absorbs ultraviolet radiations and thus prevent us from harmful effects like skin disease.

Which of the following is/are the advantages of global warming?

  3. The green-house effect

  4. All of the above

Show answer
Correct Option: D
Explanation:

Which of the following effect is due to global warming?

physics heat and energy causes of greenhouse effect global warming adaptation in animals

  1. Water shortages in already water-scarce areas.

  2. Increased deaths from heat waves.

  3. Extinction of additional species of animals and plants.

  4. All of the above

Show answer
Correct Option: D
Explanation:

The effects of global warming or climate damage include far-reaching and long-lasting changes to the natural environment, to ecosystems and human societies caused directly or indirectly by human emissions of greenhouse gases. It also includes the economic and social changes which stem from living in a warmer world. Global warming stresses ecosystems through water shortages in already water-scare areas. increased deaths from heat waves, extension of additional species of animals and plants etc.
