Weekly Quiz Competition

Question 1
1 / -0

Chemical species present in the environment are either naturally occurring or generated by human activities. The study of their interaction with and effects on the environment is called as:

A
environmental pollution

B
environmental chemical interactions

C
Environmental chemistry

D
environmental studies

Solution

Environmental chemistry basically deals with the origin, transport, reaction and effects of various chemical species of natural or human origin in the environment. It is a part of environmental studies that deals with all other aspects and interactions of environment.
Question 2
1 / -0

The effect of undesirable changes in the environment causing harm to living beings is termed as:

A
Environmental biology

B
Environmental pollution

C
Environmental chemistry

D
Environmental studies

Solution

Environmental pollution is the harmful effect of undesirable changes caused by substances of chemical, biological or human origin.
Question 3
1 / -0

Dichloro-diphenyl-trichloro-ethane (DDT), plastic materials, heavy metals etc. belong to which of the following category of pollutants in environment :

A
Slowly degradable

B
Bio-degradable

C
Non-biodegradable

D
None of these

Solution

DDT, plastic materials and heavy metals like cadmium, mercury and arsenic are not degradable by natural biological processes by bacteria or any other microbe. Therefore they are non-biodegradable.
Question 4
1 / -0

Which of the following pollutants can degrade by natural processes :

A
Majority of chemicals

B
Refrigerant materials

C
Nuclear waste

D
Vegetables

Solution

Vegetables have cell walls made up of cellulose which is a natural polymer and thus is bio-degradable, so they breakdown by natural processes.
Question 5
1 / -0

Tropospheric and stratospheric pollution are actually the components of :

A
Environmental pollution

B
Soil pollution

C
Water pollution

D
Atmospheric pollution

Solution

Tropospheric and stratospheric pollution is the pollution associated with tropospheric and stratospheric layers of atmosphere so they are components of atmospheric pollution.
Question 6
1 / -0

Stratosphere is a region of the atmosphere which contains:

A
Plants

B
Air

C
Ozone layer

D
Water vapour and clouds

Solution

Stratosphere, which is the second layer of atmosphere, contains ozone layer that absorbs UV-radiation from sun's rays.
Question 7
1 / -0

Troposphere is a region of the atmosphere which contains:

A
Dinitrogen and dioxygen gases

B
Little water vapours

C
Human beings

D
Ozone layer

Solution

Troposphere is the lowest layer of the atmosphere where all living beings including humans live. It also has air, much water vapours, clouds and is turbulent in nature.
Question 8
1 / -0

Tropospheric pollution is caused by:

A
Oxides of sulphur, nitrogen and carbon

B
Cloud formation and turbulence

C
Dinitrogen and dioxygen gases

D
Chlorofluorocarbons (freons)

Solution

Various oxides of sulphur, nitrogen and carbon like SO_2,SO₃, NO, NO₂, CO and CO₂ cause tropospheric pollution and inflict harm to living beings.
Question 9
1 / -0

Acid rain is:

A
Much water vapours

B
Deposition of water polluted by toxic heavy metal residues on earth

C
Deposition of acidic gaseous pollutants on earth from the atmosphere

D
Deposition of organic wastes on earth

Solution

The acidic gaseous pollutants like oxides of sulphur and nitrogen react with water and come down to earth in form of acid rain.
Question 10
1 / -0

Sewage containing organic waste should not be disposed in water bodies because it causes major water pollution. Fishes in such a polluted water bodies die because of:

A
Large number of mosquitoes

B
Decrease in the amount of dissolved oxygen in water

C
Clogging of gills by mud

D
Increase in the amount of dissolved oxygen

Solution

Organic waste disposed in water bodies causes the death of fishes because bacteria present in them decompose the organic waste and consume oxygen in it leaving lesser oxygen for fishes and other aquatic animals for respiration.
