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

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.

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 biology living world of animals causes of greenhouse effect global warming adaptation in animals

Many animals have physical adaptation of blending to the environments. This is known as

  1. Mimicry

  2. Behavioural

  3. Migration

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

  1. Mimicry is considered to be the copy of action or behavior of someone or something. It can be in the form of sound, smell, behavior etc.
  2. Behavioral adaptation is the one that organism adapts for the survival. It includes migration, hibernation etc.
  3. Migration is the process in which animal moves large distances in order to avoid seasonal stress. 
  4. Camouflage is a combination of material, colouration and illumination that helps organism either to hide or disguise itself. 
So, the correct option is 'Camouflage'.

Multiple choice commercial applications global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

Read the following statements and select the correct option.


Statement 1: Ozone layer present in the stratosphere protects the living organisms from harmful UV rays coming from the sun by absorbing nearly all of them.

Statement 2: Ozone formed in the troposphere by photochemical reactions as a result of human activities which is harmful to all living organisms.

  1. Both statements 1 and 2 are correct.

  2. Statement 1 is correct but statement 2 is incorrect.

  3. Statement 1 is incorrect but statement 2 is correct.

  4. Both statements 1 and 2 are incorrect.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

'Good ozone' is found in the upper part of the atmosphere called the stratosphere and it act as a shield by absorbing ultraviolet radiations from the sun. UV rays are, highly injurious to living organisms. 'Bad ozone' is formed in the lower part of atmosphere called troposphere and it harms plants and animals.

Multiple choice commercial applications global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

The major ozone depleting substance out of the following is _____________.

  1. $ { CFC }{ s } $
  2. $ { O } _{ 2 } $

  3. Nitrogen

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

Ozone-depleting substances (ODS) are substances that react with ozone present in the stratosphere and destroy the same. The major Ozone-depleting substances are chlorofluorocarbons (14% of total depletion), nitrogen oxides (3.5% depletion), sulphur dioxide, halon, carbon tetrachloride, methyl chloroform, chlorine, etc.

Multiple choice commercial applications global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

Increasing skin cancer and high mutation rate are the result of _______________.

  1. Ozone depletion

  2. Acid rain
  3. $CO$ pollution
  4. $ { CO } _{ 2 } $ pollution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ozone depletion occurs widely in the stratosphere due to an increased amount of $ { CFC }{ s } $ which causes various types of skin cancer and mutations.

So, The correct answer is (A)- Ozone depletion.

Multiple choice zoology global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

The maximum hole of ozone is found over ______

  1. Arctic zone

  2. Antarctic zone

  3. Tropical zone

  4. Subtropical zone
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Ozone-depleting substances are present throughout the stratospheric ozone layer because they are transported great distances by atmospheric air motions. The severe depletion of the Antarctic ozone layer known as the “ozone hole” occurs because of the special atmospheric and chemical conditions that exist there and nowhere else on the globe. The very low winter temperatures in the Antarctic stratosphere cause polar stratospheric clouds (PSCs) to form. Special reactions that occur on PSCs, combined with the relative isolation of polar stratospheric air, allow chlorine and bromine reactions to produce the ozone hole in Antarctic springtime. 
So, the correct answer is 'Antarctic zone'.
Multiple choice zoology global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

The ozone layer in earth's atmosphere is crucial for human survival because it

  1. Has ions

  2. Reflects radio signals

  3. Reflects ultraviolet rays

  4. Reflects infrared rays
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

An ozone layer, present in the stratosphere, reflects the ultraviolet rays emitted by the sun and thus it prevents us from skin diseases and mutation.

So, the correct answer is option C.

Multiple choice zoology global environmental change causes of resource depletion causes of greenhouse effect ozone layer depletion

The main factor responsible for the depletion of ozone layer is addition of _____in the atmosphere.

  1. $Mn$
  2. $Cl$
  3. $Na$
  4. $Co$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The main factor responsible for the depletion of ozone layer is addition of Cl in the atmosphere.
Each Cl atom can destroy as many as 100,000 ozone molecules. Cl atoms comes from chlorofluorocarbons.
