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

What are the consequences of the Global Warming?

  1. Decrease in Earth's temperature have resulted in Ice Ages

  2. A rise in sea level

  3. Stronger storms and where they occur, a change in where foods can be produced, and stress on plants that will not have had enough time to adapt

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

Climate change could result in global, large-scale changes in natural and social systems.Examples include the possibility for the Atlantic Meridional Overturning Circulation to slow- or shutdown, which in the instance of a shutdown would change weather in Europe and North America considerably, ocean acidification caused by increased atmospheric concentrations of carbon dioxide, and the long-term melting of ice sheets, which contributes to sea level rise.

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

Which of the following is correct regarding the effect of global warming on human?

  2. An increase in temperature can result in a longer life cycle for diseases.

  3. Global warming can affect our future ability to obtain food.

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

Global warming has brought about possibly irreversible alterations to Earth's geological, biological and ecological systems. Global warming affect on climate can adversely affect humans. An increase in temperature can result in a longer life cycle for diseases. Global warming can affect our future ability to obtain food.

Multiple choice chemistry air and water pollution control environmental impact: global warming green house effect geobiochemical cycle

Increased level of greenhouse gases causes global warming which will result in:

  1. biomagnification

  2. eutrophication

  3. melting of glaciers

  4. ozone depletion
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The earth's atmosphere traps the heat from the sun, preventing it from escaping into space is the greenhouse effect. This is mainly caused by deforestation. This results in an increase in average temperature of the atmosphere due to which glaciers start melting and there is a rise in sea level. 

Multiple choice chemistry pollution of air and water environmental impact: global warming green house effect geobiochemical cycle

The progressive warming up of the earth's surface is mainly due to :

  1. automobile exhaust

  2. blanketing effect of carbon dioxide in atmosphere

  3. reforestation

  4. thickening of ozone layer
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

$CO _2$ goes in the atmosphere and make a thick layer, this layer allowes the light to enter into the atmosphere but do not allow it to exit, the heat get trapped into the atmosphere and leads to the warming up of the surface.

Multiple choice chemistry natural resources- air, water and land environmental impact: global warming green house effect geobiochemical cycle

Green house effect of global warming causes:

  1. rise in temperature of earth

  2. rise in pressure on earth

  3. decrease in oxygen content earths atmosphere
  4. decrease in $CO _{2}$ content
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere.

The progressive heating up of surface of the earth is earth is called green house effect or global warming.

CO$ _2$ and H$ _2$O block a part of the heat (IR) emitted by the earth & reflect back. Due to this earth surface gets heated up.
50% in CO$ _2$ content of air can increase the surface temperature of the earth by 3$^o$ C.
In addition to CO$ _2$ , the other green - house gases are CFCs (17%), O$ _3$ (18%), NO (4%), water vapour (2%).

Thus, the correct answer is option A. 
Multiple choice chemistry air and water pollution control environmental impact: global warming green house effect geobiochemical cycle

Greenhouse effect causes:

  1. melting of ice caps

  2. rise in the sea level

  3. submerging of low lying areas

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

The greenhouse effect causes the melting of the ice caps and releases other greenhouse gases, $CH _4$ which is heating up the environment and causing the greenhouse effect again. 

Option A is correct.

Multiple choice biology air and water pollution control environmental impact: global warming green house effect geobiochemical cycle

Global warming causes:
1) an increase in the sea level
2) the melting of ice at mountain peaks
3) a decrease in food production by plants

  1. I only

  2. I and II only

  3. II and III only

  4. I, II and III
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The global warming effect causes the rise in the global temperature resulting in melting of polar ice caps and rise in sea level.This rise in temperature changes the rain cycle and it decreases the crop production.

Multiple choice biology air and water pollution control environmental impact: global warming green house effect geobiochemical cycle

Cause:

Global warming
Effect:
Ice at North and South poles may melt causing sea-level to rise and floods to occur.

Which of the following can prevent the effect from happening?

  1. Deforestation

  2. Use of unleaded petrol

  3. Use of leaded petrol

  4. Both (A) & (B)
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Using unleaded petrol reduces the emission of harmful pollutants, though global warming is primarily driven by CO2. Among the choices, it is the only one that represents a move toward cleaner energy compared to deforestation or leaded petrol.

Multiple choice chemistry air and water pollution control environmental impact: global warming green house effect geobiochemical cycle

The greenhouse effect is useful because:

  1. it reduces water pollution

  2. it increases normal temperature of earth

  3. keeps the temperatures on our planet mild and suitable for living things

  4. reduces greenhouse gases
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The greenhouse effect is useful because trapping some energy keeps the temperatures on our planet mild and suitable for living things. Without its atmosphere and the greenhouse effect, the average temperature at the surface of the Earth would have been very low.

Multiple choice biology air and water pollution control environmental impact: global warming green house effect geobiochemical cycle

Global warming leads to:

  1. increase in actual temperature of earth

  2. decrease in actual temperature of earth

  3. no change in temperature

  4. change in pressure
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate.

Multiple choice evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources) fuel and conservation

An increase in content of carbon dioxide in environment will not cause:

  1. more heat to be retained by environment

  2. increase in photosynthesis of plants

  3. global warming

  4. abundance of desert plants
Reveal answer Fill a bubble to check yourself
B,D Correct answer
Explanation

An increase in content of carbon dioxide in an environment will not cause increase in photosynthesis of plants and abundance of desert plants.

Carbon dioxide is a greenhouse gas, so it traps the heat radiation and causes greenhouse effect.
Increase in concentration of green house gas will result in increase in average temperature of the earth. Thus it causes global warming.
